The following notes were taken from:

  • My chat log of the Content Creation User Group (CCUG) meeting of Thursday, January 29th, 2026 and my chat log of that meeting
  • Pantera’s video (embedded at the end of this article) and my chat log of the Open-Source Developer (OSD) meeting held on Friday, January 30th, 2026.
Table of Contents

Please note that this is not a full transcript of either meeting but a summary of key topics.

Meeting Purpose

  • The CCUG meeting is for discussion of work related to content creation in Second Life, including current and upcoming LL projects, and encompasses requests or comments from the community, together with related viewer development work.
    • This meeting is generally held on alternate Thursdays at Hippotropolis and is held in a mix of Voice and text chat.
  • The OSD meeting is a combining of the former Third Party Viewer Developer meeting and the Open Source Development meetings. It is open discussion of Second Life development, including but not limited to open source contributions, third-party viewer development and policy, and current open source programs.
    • This meeting is generally held twice a month on a Friday, at 13:00 SLT at the Hippotropolis Theatre and is generally text chat only.
  • Dates and times of meetings are recorded in the SL Public Calendar.

Official Viewer Status

  • Default viewer 2025.08 – 7.2.3.19375695301 – maintenance update with bug fixes and quality of life improvements – December 2 – No Change.
    • Notable addition: new VHACD-based convex decomposition library for mesh uploads.
  • Second Life Project Lua Editor Alpha version 7.2.3.19911032641, December 5 –  No Change.
  • Second Life Project Voice Moderation viewer 26.1.0.20139269477, December 12 – No Change.
    • Introduces the ability to moderate spatial voice chat in regions configured to use WebRTC voice.
  • Second Life Project One Click Install viewer 26.1.0.21295806042, January 26, 2026 – one-click viewer installation.

Upcoming Viewers

Viewer 2026.01 – One-click Installer / Updater

  • Now available as an alpha viewer (above).
  • As the name suggests, triggers a one-click install / viewer update process.
  • Is still being worked on, with a focus on ironing out some kinks in the one click install, including an uninstaller for old non-velopack viewers that can be triggered when required, the usual registry stuff for Windows, and so on.
  • Also includes improved monitoring / logging of viewer freezes and crashes, etc.

Viewer 2026.02 – “Flat” UI, Font Changes

Example of the upcoming flat UI. Via: Geenz Linden / Github #4681/2
  • This viewer is to be part of the Lab’s “first impressions” push to make SL resonate more with incoming new users and hopefully encourage them to keep logging in.
  • Will include a new “flat” UI (as seen in the Project Zero (viewer in a browser) version) which comprises things like a font change, a colour scheme change,  and generally giving the viewer a more “modern” look and feel. This is not a major UI overhaul in terms of overall look and feel, more an aesthetic one.
  • Font changes within this viewer are currently described as “experimental”.
  • Also looking like it will include a log-in landing refresh.

General Viewer Notes

  • Work on clearing viewer bugs and implementing smaller feature requests into the viewer is continuing, so users can expect more of this, allowing for other priorities in viewer work.
  • On the viewer development side:
    • There should be some vcpkg movement in the near future. A Pull Request for this work via a third-party developer is apparently in progress, but will not be shipped immediately on approval. Rather, it will be allowed “soak time” so other developers can assess impact on their build pipelines downstream and the like.
    • There will also be some CMake project changes, although these appear to be more of a “modernization” push, to bring CMake in the viewer into line current CMake project norms.
  • LL is contemplating bringing back viewer maintenance releases to try to encourage some TPVs to pick-up bug fixes and incorporate them faster into their viewers (rather than waiting for a major viewer update which includes bug fixes to get to release status and then merging them).
    • If this is done, the maintenance releases will be “much smaller in scope” than past maintenance updates (so a kind of taking bug fixes that are flowing into upcoming major viewer releases, cherry picking them and then QA’ing and releasing them as a small update to the viewer.
    • Those TPVs at the meeting indicated this could either add to their workload or that they would not alter their existing workflow due to overheads, but instead will continue to cherry-pick upstream fixes as a part of their own release cycles.
  • In response to questions on whether Kitty Barnett’s RLVa code contributions will be included in the official viewer (and which are currently pending fixes she has submitted for RLVa avatar appearance fixes anyway), Geenz Linden stated:
If we did, it’d likely be a very progressive and targeted thing that we do. And hopefully not in a way that significantly makes downstream more difficult to maintain. It’s a longer discussion that needs to be had basically. 
    • This led to concerns that LL could end up implementing a variant of  RLVa that is at odds with the current RLV/RLVa API, and effectively end up being ignored for being incompatible. In response, Geenz further noted:
I’d prefer one that everyone can participate in if we do go that route so we can be more targeted with others helping to guide that. Last thing we want to do is make it take 7 months to ship a TPV just because we made a change to RLVa. We also have to consider overall content compatibility and such.
  • Also as per the last meeting, official Linux support is aligned with the in-progress SLua viewer .

“First Impressions” Context

  • This work is focused on trying to ease that first experience for a lot of new residents to try and drive up retention numbers.
  • The work is seen more-or-less as experimentation at this point in time, but the goal is to drive up first day engagement among incoming new users to encourage them to continue to log-in to SL.
  • Work on this is on multiple fronts, and more will be shared on it in due course.

Grid-Wide WebRTC Deployment

  • The Lab is currently looking at a March deployment of WebRTC voice across the grid, but this is subject to possible change.
  • The viewer server is currently in a beta soak test (see: WebRTC Voice Open Beta is Expanding).
  • The last major server crash has been fixed, and there have been none since that fix went in.
  • There is an upcoming fix – see Pull Request #5322  (included in viewer 2026.01) – to address some of the issues with voice dropping. The recommendation is for TPVs to get this into their viewers for a good user experience.
  • An upcoming server-side update will hopefully address some of the issues with WebRTC spatialisation (e.g. voice volume varying greatly with even small camera position movements on the part of a listener).
  • Additional connection tweaks for WebRTC have been made to the 2026.01 viewer to help improve voice performance (e.g. to improve auto-reconnect).
  • Feedback on people’s experiences with WebRTC is still being sought (notably via the beta testing).

SLua Update

  • An update to the SLua project viewer is forthcoming.
  • As noted above, this will bring with it support for Linux
  • Still no confirmation as to when SLua will go live across SL

General Discussion

OSD Meeting

  • SSR and PBR water real time reflections and shadows: Geenz indicated that work is progressing on this and that when available, it will be given “a proper” alpha/beta/Release Candidate process.

  • The was noted that whilst improvements on SSR and PBR water reflections are being made, they will never 100% match pre-PBR views without a lot of work being put into optimisation, what would likely still result in mixed feedback without any significant win.
  • This led to a general discussion on addressing water reflections and shadows.

CCUG Meeting

  • PBR lighting: still on the list of potential updates, but requires “quite a few” server-side changes in order for it to happen.
    • The existing SL lighting system has a range of constraints dating back 20+ years, and so would require significant modification in order to enable PBR lighting support.
    • As such, this is currently viewed as being on the back burner for the foreseeable future, while other things are worked on.
  • A question was asked on whether it would be possible for an Animesh using only ten bones in total to have a lower Land Impact / rendering cost than one rigged to 10 out of the 110 bones of the default skeleton. Short answer: no, not without custom rigs.
  • Custom rigs themselves are acknowledged as something SL should have, but the work involved in enabling them is extensive and touches on multiple areas (e.g. re-targeting bones for clothing fits; re-targeting animations – and even a couple overhaul of the animation system -, etc.). There is also work to be carried out elsewhere that would yield benefits for things like quality of life which are of a higher priority. As such, custom rigs are not something currently on the roadmap.
  • In-world mesh creation tools: unlikely to be a thing, as the implementation would be costly in time and effort, and likely would not measure up to the capabilities of external tools like Blender.
  • It was asked if the import route for rigged meshes could be “streamlined” without the need for AvatarStar / MayaStar. Neither of these tool are actually a requirement for rigged mesh import / export, rather they are tools that can help with the process of rigging from within SL. Meshes that have been correctly rigged and weighted using external tools should import correctly through the current import mechanisms (COLLADA or glTF).
  • Overhauling the mesh import file format  / process through the support of something like OpenUSD is an idea that is being mulled over within the Lab. However, a) this is not something that is likely to be prioritised in the next 12 months; b) it is something that would require a lot more in the way of discussion before moving towards it; c) there is still work to be done in improving the import / export of currently supported formats before trying to add to them / replace them.
  • Materials import for meshes: this is something the Lab wanted to implement for glTF mesh import (rather than having to import materials separately).
    • However, due to the way in which asset uploads to SL work, it proved to be more a complex issue than first thought.
    • The hope is that the work can be returned to in the future, possibly using a new import flow that is more in line with other platforms and tools, but this is not something on the current roadmap.
  • PBR specular support: this is still something Geenz would personally like to get done, but it is currently sitting behind various other items which need to be completed / implemented in order to clear time for working on it. Also, this work does have impacts on things like the glTF upload validator, scripting, simulator support, managing glTF overrides (which are currently not well handled) etc., all of which would have to be factored into the work and which are outside of Geenz’s immediate responsibilities.
  • In terms of extending glTF support in general (PBR specular, IoR, etc.), the preference at the moment is to fix more of the existing issues / bugs within the existing PBR capabilities before adding further options.
  • The meeting was somewhat sidetracked by talk on the use of bots, ToS bot violations, Tiny Empires, etc., the majority of which are more of a Governance issue.

Time in the beauty of The Great Mother in Second Life

The Great Mother, January 2026 – click any image for full size

Benny Voxtex, whom I last wrote about in covering his (now closed) club, [Refuge]  – see: A [Refuge], a Deep Box, and a splash of absinthe in Second Life – recently invited me to preview his latest creation, The Great Mother. And all I can say is, “Wow!”

Fans of the Avatar franchise may recognise the term, given it is one of two “common names” (so to speak) by which Ewya, the globally distributed consciousness of Pandora is known; the other being the All-Mother. As such, it should come as no surprise that this is something of a personal homage to the Avatar movies whilst also being entirely unique as a setting in its own right; a place of infinite beauty; one that is utterly immersive.

Dive into the deep primordial forest, an ongoing passion project for Benny Vortex. Discover a lush, bioluminescent dreamscape of sights and sounds nestled below breath-taking floating islands under the silent gaze of a gas giant. May the spirits guide you.

– The Great Mother’s Destination Guide description

The Great Mother, January 2026

Occupying a Full region called – appropriately enough – Eywa, the setting captivates from the start. But before getting into specifics, there are some recommendations for enjoying a visit:

  • Preferably, visit using a PBR-enabled viewer.
  • Make sure you enable the local music stream to enjoy a soundtrack fully in keeping with the setting.
  • Use the shared region environment settings.
The Great Mother, January 2026

Also, make sure you have local sounds enabled – this is an absolute must, as Benny has created an immersive soundscape, covering everything from the deep, echoing sounds of Pandora’s forests and creatures through to the sound of your own footsteps rustling the moss and grass. That said, don’t expect to encounter any of Pandora’s beasts – or ioang – whilst you may hear them in the distance, this is a place of sanctuary and spiritual awakening. However, if you opt to visit in a Na’vi avatar, that would be both appropriate and welcome.

Finally, do be aware that The Great Mother is very much a work in progress: whilst now open at the ground level, Benny has plans for vertical expansion and more. In fact, the Landing Point itself is in the air and presents the first of the setting’s unique elements.

The Great Mother, January 2026

Forming a small island, the landing Point is marked by a number of rope slides. Each of these bares a symbol scratched into its wooden frame, indicating the area of the biome below in which you will arrive. Pick the one you fancy and ride it down to a smaller floating island, where a dive mat awaits.

Sit on the dive mat, select your preferred dive (and style, if offered), and take the leap! Whichever area of the biome you selected, you will land in water. As you do so, a dialogue box will be displayed with a couple of options – one being a return to the diving mat and going again, if you wish.

The Great Mother, January 2026

However, to explore, ignore the dialogue – but do not stand up. You are still running an animation tied to the dive mat, and you can use it to swim through the water and / or to shore, where upon the animation will release you and allow you to walk.

Whichever rope slide you take, it likely won’t be the last, within the forest and waterways below are ropes to climb and rope traverses pass through the higher boughs, and trails over land and across water to be explored, together with discoveries to be made.  Keep an eye out for seeds marking potential points of interest as you explore. Overhead, further off-region islands hang in the night sky whilst a massive Jupiter-like gas giant watches over the comings and goings of this living world.

The Great Mother, January 2026

Extensive use is made of Elicio Ember’s fabulous plants, their bioluminescent fronds and petals well suited to representing Pandora’s own rich mixture of plant life, and this further brings the setting to life. As with the ideals of Eywa as well, there is a balance of lands and water throughout the region, with water channels as much as dry land trails offering routes of exploration – indeed, as Benny noted to me, the entire region is navigable by canoe.

As to what drew him to create such an environment, ad his future plans for expansion, Benny had this to say:

I really love the concept of the film and as a biologist/mycologist RL I can’t get enough of bioluminescent organisms. The next mission will be above 1000m with floating islands and waterfalls, and as I’ve also put a deep channel running through the region, I will eventually make it mer-friendly, and such.

– Benny Vortex on developing The Great Mother

The Great Mother, January 2026

Merfolk per se might not be a formal part of the Pandora ecosystem – although the Na’vi clearly have a relationship with the seas of their world – providing such a merfolk environment within The Great Mother does, to me, fit, and further extends the inclusiveness of the setting as a whole.

While I could write far more on the region, the truth is, it doesn’t need explanation – it deserves exploration and time spent with in it. As such, I’m going to wrap this up with a thank you to Benny for the invitation and the chance to explore for myself, and to strongly urge all Second Life explorers to visit Eywa and The Great Mother.

January 2026 SL Mobile UG meeting summary

Campwich Forest grounds: location for the Monthly Mobile User Group (MMUG)
The following notes were taken from the Thursday, January 29th 2026 Monthly Mobile User Group (MMUG) meeting. These notes should not be taken as a full transcript of the meeting, which was largely held in Voice, but rather a summary of the key topics discussed.

The meeting was recorded by Pantera, and her video is embedded at the end of this summary – my thanks, as always to her in providing it.

Table of Contents

Meeting Purpose

  • The Mobile User Group provides a platform to share insights on recent mobile updates and upcoming features, and to receive feedback directly from users.
  • These meetings are conducted (as a rule):
    • The last Thursday of every month at 12:00 noon SLT.
    • In Voice and text.
    • At Campwich Forest.
  • Meetings are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Current Releases

SL Mobile (Beta) version 2025.1075 (A) / 0.1.1075 (iOS) – December 12, 2025 – Avatar loading improvements.

New Starter Experiences Update

[Video: 5:37-7:08]

  • SL Mobile is seeing new users signing-up and joining SL, this led to the creation of a series of New Start Locations for those coming in via Mobile to be able to easily reach, and which have been put together by the location creators specifically to be Mobile-friendly.
SL Mobile New Starter Experiences front-and-centre.
    • The range of available experiences is being expanded, with the latest being a Brazilian-based experience – the Brazilian Beach Hangout – offering Voice in both English and Portuguese.

SL Mobile Alpha

[Video: 7:13-8:53]

  • As many are aware (and a part of ), there is an invite-only SL Mobile Alpha group providing early access to users to help test upcoming Mobile features and updates prior to them being made publicly available through the main Beta programme on Android and iOS.
  • The app for this programme is entirely separate to the app available via the Apple and Google stores.
  • The most recent releases to Alpha include Bubble Chat and single-taps.

Bubble Chat

  • This is is response to complaints about having to switch views / trying to remain in contact with the in-world scene when using chat.
  • Allows chat and incoming IM’s to be viewed over the in-world scene, and allow tap-to-reply.
  • In the initial iteration, tapping a message to reply will still take a user back to the menu to show the keyboard.
  • However, as the feature is expanded, it is hoped that it will enable the keyboard overlay to be displayed over the in-world scene to allow for faster responses without having to switch away.
  • Bubble Chat is also seen as a means of encouraging greater use of Mobile rather than just a quick “checking in” tool.

Single Tap to Interact

[Video: 10:07-11:45]

  • Interactions with SL Mobile can be “tedious” in terms of the number of taps, etc., required to initiate an action – such as chatting, finding a person’s name  / profiles, etc., and even interacting with objects.
  • Single Tap to Interact replaces the current long press required to garner a response from objects in the world view (display the context menu). When tapping on an item, Single Tap will display the top items in the context menu as an overlay to the in-world view. So for example:
    • Tapping on an avatar will display the options to send an IM or Friend request or expand the menu to see more options – such as their Profile.
    • Tapping on an in-world object will similarly display the most common options in the context menu (e.g. “sit” if it is chair / seat), with an option to display the rest of the context menu.
  • Like Bubble Chat, Single Tap is seen as a means to increase on-going use of SL Mobile beyond being an adjunct to using the viewer, and allow greater opportunity for users to be active in SL when using Mobile.

Technical Notes on Both

[Video:  12:43-17:21]

  • Bubble Chat is seen as relatively “easy” to implement, outside of one or two quirks in how Unity handles uniformity of presentation of things like overlays, which does require a little additional work to solve.
  • Single Tap to Interact is a more complex subject, as it not only involves changes to the underlying touch functionality, it is also attempting to more accurately map on-screen taps to ensure the right focus and the the resultant correct menu is displayed.
    • On-screen interactions – touch, tap, etc., – can be seen as collisions, which require a degree of physics calculations. Generally in SL the vast majority of physics interactions and collisions are managed by the server – the viewer is essentially “dumb” to them.
    • With Mobile, this can lead to inaccuracies arising between where the screen is touched and where the simulator thinks it has been touched, simply because of the network latency involved in back-and-forth communications and calculations, resulting in the noted frustrations with long-touch, etc.
    • So as a part of the implementation of Single Tap, it was decided to incorporate some of the physics-related calculations into the app itself.
  • Incorporating physics calculations into the app has involved building a “mini physics simulator”, capable of loading all of the physics colliders into the app’s already constrained memory limits (so effectively pre-caching them), and providing a means for the colliders and calculations to be recognised by, and accurately passed between, two different physics engines  – Havok on the simulator, Unity’s own in the app.
  • Whilst complex, this has resulted in a significant reduction in latency between touch and response and in ensuring the relevant menu appears, and with little to no added latency resulting from the device hardware having to do all the pre-caching and calculations. the only appreciable impact is on networking bandwidth during the pre-caching process.
    • A further help here is that the Unity physics engine can be switched off excepted for when actually required, thus removing a continuous overhead for the app.
  • This work will also help with other physics-related interactions down the road.

Future Work

[Video: 29:41-34:39]

  • Stability: the Lab uses both their own internal metrics and those from the app stores to monitor SL Mobile’s overall stability.
    • There has been a steady decrease in Android crash rates, and a further fix is coming in the next production beta release of Mobile.
  • New work being initiated (no due dates / target release dates at present):
    • Persistent chat (i.e. chat histories persisting between Mobile and viewer, rather than being broken by using one or the other).
    • Chat logging.
    • More work on language localisation for Mobile.
  • Map and Search:
    •  Search: Web search is already Mobile responsive, but hard to use. To overcome this, this preferred route at present is to take Web Search and put it into Mobile as an embedded view. This requires a certain amount of work, which is in progress in terms of how to best present Web Search within the app and ensure its performance, prior to actually embedding it into the the app.
    • Map support: starting to be looked at as a facet of Search, with the hope that the two will be fairly well integrated with each other in the future and where relevant (e.g. toggling between Search and the Map when searching for places). Once this is in place, the Mobile team will look to build further viewer World Map functionality into the Mobile Map.

General Q&A

  • What is SL Mobile’s maximum Draw Distance?
    • Up to 250 metres can be selected (but not recommended), but the app currently defaults to 40-50 metres to reduce the memory load.
    • As a rule of thumb, every additional 10 metres of draw distance can result in 30%+ of the app’s memory allocation (determined by the OS / hardware) to rendering alone.
    • Higher distances can be set at the user’s discretion via settings, but these can impact performance., and many of the higher settings (100m+) are not recommended for general use, as noted here and in the app.
    • A danger with exceeding memory limits in an app is that the OS will simply drop it without warning.
  • Concern was expressed about content being suitable for Mobile consumption – LODs, Land Impact, etc., – and on the need to encourage content creators to think Mobile in their work.
    • The Mobile app does actually carry out a degree of object culling to lighten the load – small objects, for example, aren’t rendered unless directly focused upon.
    • There have been internal discussions at the Lab about Land impact and how it relates to Mobile, but no firm decisions have been taken.
    • The matter of LODs and content creation tools vis-à-vis Mobile has also been discussed, but again, no firm decisions have as yet been made. LOD models are a part of a wider discussion overall for SL, given they also impact lower-specification hardware running the viewer, and there are on-going talks (e.g. through the Content Creation User Group) on LODs, automatic LOD generation, decomposition tools, etc.
  • PBR, Shadows and EEP support:
    • PBR – not yet.
    • Shadows – yes, supported, but is device-dependent, as shadow rendering is expensive (e.g. can as much as triple the rendering complexity for a scene).
    • EEP – limited support, with two passes of integration carried out so far. More work is required on this (e.g. average scene lighting to bring Unity’s lighting more into line with how scenes appear on the viewer), but it is not an easy task in terms of future maintenance.
  • Will SL Mobile support:
    • In-scene dialogue menus (i.e. the blue menus displayed when touching scripted object in the viewer)? – Yes, possibly in the next couple of months.
    • A walk / run / fly toggle on the movement joystick? – This is something that LL would like to support down the road.
  • Alpha Texture support: there are two primary issues in managing alphas on Mobile:
    • Formats: the viewer uses JPEG2000 for textures, Mobile uses a variety of formats which are hardware-dependent, and so additional work such as switching out texture formats is required – which itself can be problematic (e.g. can invalidate texture caches and cause issues such as slow loading, etc.).  However, Adam Sinewave (Mobile Lead Developer) does have a potential fix for this in the works.
    • Tiled-based GPUs: these are common on mobile hardware and do not like overdraw (rendering the same texture multiple times, required for alphas).
    • Both of these mean that Mobile uses a mix of dithered alpha rendering and temporal anti-aliasing to achieve the desired result. This actually simplifies alpha rendering on Mobile, but does produce unwanted artefacts on transparency, some of which will be hopefully resolved, others of which might continue to result in differences in how alphas appear on Mobile compared to the viewer.
  • Will SL Mobile be made available through other mechanisms than Google Play Store? Possibly, the idea of providing Android Package Kits (APKs) has been discussed, but brings with it a distribution problem. Also, the idea of using Google’s update mechanism for apps has also been discussed, which would bind SL Mobile more to the Google Play Store.
  • Minimum requirements for Mobile: these are somewhat hardware constrained (CPU / GPU pairing). As a broad rule of thumb, SL Mobile requires a device with at least 4Gb of RAM, and preferably a more recently SoC combination of CPU/GPU.

Exploring the regions of Isola Sirena in Second Life

A view of Isola Sirena, Second Life - the main island summit village
Isola Sirena, January 2026 – click any image for full size

I came across Isola Sirena whilst perusing the Destination Guide. Comprising a pair of Full private regions, each leveraging the Land Capacity bonus offered by Linden Lab for such regions, it is an expansive, multi-faceted, multi-level setting with a lot to see and do throughout.

The work of Angel Kavanagh-Taylor (AngelWaldencork) and SL partner Kina Finest-Taylor-Kavanagh (Kina Amour), the setting also possesses several secrets worth discovering. The main starting point for explorations is located in the more westward of the two region, Isola Sirena – Sunkissed Cove Beach.

A sun-drenched Mediterranean-inspired sim offering sweeping coastal views and dreamy escapes. Explore a hilltop restaurant, mini golf in the clouds, a charming winery and farmers market, and a stunning beach, with beautiful beachside and villa rentals.

– Isola Sirena About Land description.

A view of the Isola Sirena, Second Life - Hidden Retreat
Isola Sirena, January 2026

It is here, perched on a high mesa, is a complex of Landing and Information point, offering teleport boards to reach the majority of the setting’s major locations, several of which are located within the complex itself: the Game Room, La Vetta d’Oro, Mixology Bar, and outside, via the terrace, the Summit Infinity Pool and the Plaza. However, the best way to explore and discover most of the locations is on foot (with one exception!).

On the south side of the mesa lies a small village reached by one of two routes from the Landing Point complex. This, like the mesa’s summit, offers clear views out to the off-region surrounds which give the impression both regions are part of a broader Mediterranean location. However, to fully appreciate the extent of this, Draw Distance will likely have to be raised.

Isola Sirena, Second Life - open view
Isola Sirena, January 2026

Parts of the village appear to be for rent as businesses or homes. How extensive these rentals might be wasn’t clear to me: many were empty; and without rental boxes, others were furnished as homes and include rental boxes. The village and its footpaths step down toward the region’s beach, passing by way of La Tavola di Eleanora Café, which can also be reached via the main teleporter boards, as can the beach below.

The beach itself offers a mix of public spaces and rental beach cabins, together with the hackney carriage ride, a jet ski rezzer, a swim assist board and the beach bar. At the south-western end of the beach can be found the Meditation Point and Beach Club, both reached via the Teleporter boards, and the former also by the Beach boardwalk.

A view of the Isola Sirena, Second Life - Cavern Baths
Isola Sirena, January 2026

A covered bridge provides access to the setting’s mid-point island, home to the stables and farmer’s market, and which also provides bridge access to an eat-point tongue of land extending out from the base of the mesa to connect with the second region of the setting. The appears to be largely given over to villas available for rent. However, it is also home to one of the setting’s secrets: the bathing cavern.

This is quite exquisitely done, the entrance offering something of a backstory to the cavern’s discovery. Offering, as its name suggests, a place to bathe in warm waters offering places to sit and cuddle around the edges of the pool all set within a location suggestive of great age. The main pool surrounded by tall statues, some of whom hold shells from which water falls to replenish the pool below. It is a place suggestive of a relaxed, hedonistic beauty.

Isola Sirena, Second Life - the beach
Isola Sirena, January 2026

Set to one side of the main pool is a blank cave entrance, a sign indicating it is the way up to the sun-based caverns.

These are equally magical in their design, and also entirely otherworldly. The path through them is well signed, and there are places here to pass the time alone or in company. Exploring them is an absolute must, whether via the bathing cavern (recommended) or the main teleporter boards. Nor are these the only caves to be found within the setting – but all let you find the others, accessible as they are from the ground and (again) the Teleport boards.

Isola Sirena, Second Life - the caverns
Isola Sirena, January 2026

Eastwards, past the villa the land flows into Isola Sirena – Winery and Countryside. This again appears to be given over to villas available for rent, together with the Vetta Oro Vinicola wine bar and the Winery itself. The latter has its own secret located on the shoulder of the hill to one side of it. Guarded by a stone carving of a young (weeping?) woman, lies a stairway leading down to the wine cellar.

And there is still more to be found – from bumper boats to picnic areas and seating – and of course, the pair of small islands held aloft by balloons and home to mini golf, as mentioned in the setting’s description and which gives it a little twist of the surreal.

Isola Sirena, Second Life - the winery
Isola Sirena, January 2026

I will confess to having some small niggles with Isola Sirena. The main caverns are at altitude, and so are ideal for their own dedicated EEP setting. Similarly, the cavern baths also look as if they could be placed in a parcel with its own EEP. This would avoid the need for sign posts asking people to change their setting locally, and make the experience of exploring more immersive with seamless transitions.

Another minor niggle is with the wine cellar – the stairs down / up could benefit with rotation. As it is, they are placed in such a position that the camera is placed of the wrong side f the walls surrounding it, which can make for difficult navigation when climbing. A final small point is that raising Draw Distance to view both regions can lead to texture discards – the first time I’ve encountered this since LL worked on refining texture provisioning and loading; but there is a lot going on in both regions , texture-wise.

These niggles don’t spoil the overall impact of the regions or the setting as a whole. And it has to be said, that taken individually or together in a single visit, the regions of Isola Sirena make for an engaging visit, one worth eschewing the Teleporter boards in favour of exploration on foot.

2026 week #5: SUG Leviathan Hour – Game_Control and bits

Whithermere, January 2026 – blog post

The following notes were taken from the Tuesday, January 2th, 2026 Simulator User Group (SUG) off-week meeting (the “SUG Leviathan Hour”). These notes form a summary of the items discussed, and are not intended to be a full transcript. They were taken from my chat log of the meeting, and Pantera’s video is embedded at the end of this article – my thanks to her, as always, for recording and providing it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
  • The “SUG Leviathan Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
  • Meetings are held in text in-world, at this location.

Simulator Deployments

  • There were no planned deployments for the SLS Main Channel.
  • Wednesday, January 28th might see the next simulator update 2026.01 (Kiwi) to one or more simulator RC channels. However, this is an assumption given the status of the release last week, and no confirmation was given at this meeting.

Game Control Update

  • Leviathan Linden has cut a pre-release of the new game-control viewer, thank to work by Rye of the Alchemy Viewer.
  • If anyone tests on Linux or MacOS, Leviathan would love to have direct feedback on success/failure, either via the SUG meetings or via IM in-world.
    • In this he noted that “MacOS does some silly proprietary checks and only supports a small set of officially sanctioned controllers” and LL are limited to whatever Apple support, as otherwise the viewer doesn’t even see see hardware detection events ton Mac OS.
  • He also noted that one feature of game-control is you can allow normal avatar control inputs (either from keyboard or the UI widgets) to be interpreted as game-control events that get sent to the server. But – that mode doesn’t provide access to all the possible buttons that a game controller has: just a few of the buttons, because the game-control feature is a work in progress (WIP) and he hasn’t as yet worked out how best to map everything.

SLua Mini-Update

  • General appreciation for the work Harold Linden has put into the project, and requests at LL keep him on for the future – although he has indicated he is happy working as a contractor.
  • No news on when the latest simulator-side updates to SLua will see the light of day, but they are not in the upcoming 2026.01 (“Kiwi”) release. They Might make the cut for the follow-on 202602 (“Loganberry”) update.
  • The SLua beta viewer is progressing, and will progress to release status in due course.

In Brief

  • Leviathan gave insight into some of his work remit, and those of other members of the simulator engineering team:
    •  Some of his work is visible to residents, but he also work on internal problems: things that are causing headaches for other developers, the support team, etc.
    • Currently, he working on an issue whereby simulator states (simstates) sometimes fail to save. These appear to be related to LL’s use of a new compression scheme for simstates: zstd. This should offer faster compression/decompression and smaller packages. However, it is reporting failures every once in a while. These, Leviathan believes, appear to occur during simulator rolls. He’s still investigating this.
    • Like other members of the simulator engineering team, he is on pager duty for the week. This occurs once every four weeks, and when on pager duty, the team member is typically working on maintenance issues: bugs and such.
  • In addition, Leviathan is continuing to investigate / fact-find about the whereby when sometimes rezzing an object on a mesh surface will fail and supply an incorrect or misleading message (e.g. not having parcel rez rights or something).
  • No work has been started on addressing the wrong-number-of-faces-on-old-mesh-uploads problem yet. However, Leviathan hopes that if he can find time to start looking at this again.
  • The search for a new Senior Vice President of Engineering is on-going, and the Lab is “see great candidates”.
  • There is a reported workaround for avatars becoming stuck on a region crossings when riding a vehicle:
    • It appears possible to escape from the broken state after a failed region crossing by deleting the sit target, forcing the simulator to recompute what’s sitting on what, and seems to unjam left-behind avatars. If this works, they should be able to walk to the vehicle and re-sit (or RLV potentially used for a re-sit, if available.
    • The workaround is described as “a horrible hack”, but appears to be the best temporary “solution”.
    • Leviathan indicated he will look at it as well.
  • A general discussion on the missing SIT_FLAG_INVISIBLE, which also included llSetLinkSitFlags, a working SETMASS() flag – and its workaround and avatar bounding boxes. Please refer to the video for details.
    • The request for a working llSetMass() script method was being requested by some race bicycle creators who wanted to eliminate some variance in vehicle performance.
    • The above rolled into more general discussions and WIBNIs (“wouldn’t it be nice ifs”).
  • General discussions on the discrepancy between avatar height and prim height as reported on most viewers and avatar movement (e.g. introducing mousewalking to the official viewer) – again, please refer to the video.
  • From comments passed at the end of the meeting, it would appear that the work on implementing RLVa into the official viewer, initiated by Kitty Barnett and Vir Linden (prior to his departure from the Lab) may have been stalled.
  • It was suggested that LL carry out a limited survey of TPV users and request then list their top X TPV features that prevent them from using the official viewer. These could then be collated in terms of common requests and used as an initial starting point for possible prioritisation  / integration.
    • Exactly how a good cross-section of TPV users could be found was an open debate.
    • Managing such a task might be problem for LL, as it would require input from all of the core engineering teams to offer their input – deflecting many of them (approx 45 LL employees) for core activities.
    • Contextual note: “approx 45” does not mean that this is the total number of developers work on SL – the Lab utilises contractors on and individual and company (ProductEngine) contractors, plus a lot of general operation on the server-side are now handled through AWS.

Date of Next Meetings

  • Formal SUG meeting: Tuesday, February 3rd, 2026.
  • Leviathan Linden: Tuesday, February 10th, 2026.

The floating beauty of Sable Hound Hollow in Second Life

Sable Hound Hollow – Romantic Reverie, January 2026 – click any image for full size
Sable Hound Hollow presents a sanctuary for dreamers and a haven for lovers. Here the first whispers of Spring and the enchantment of the Hollow invite you to linger awhile and let your heart rest and your worries fade. Be it alone or with that special someone, allow the quiet beauty of this place remind you the magic of love is real.

– Sable Hound Hollow About Land

So reads a description for Sable Hound Hollow – Romantic Reverie, a setting designed by Honey Heart (H0neyHeart) as a public space for people to visit and enjoy, and forming a part of the wider Sable Hound Hollow region.

Sable Hound Hollow – Romantic Reverie, January 2026

set as a pair of islands floating just over 500 metres in the sky, this is – as the description suggests – a romantic setting, one of considerable beauty and detail and offering much to appreciate and see. The Landing Point sits on the larger, western island, located on its highest level.

Here, within a large gazebo where visitors can join the local Group and – from now through until the end of February – join in a number of events centred on a celebration of Valentine’s Day. These include a hunt (group tag required), and the opportunity to obtain a daily gift when visiting from February 1st through 14th (again, Group membership required).

Sable Hound Hollow – Romantic Reverie, January 2026

Placed within a circular garden area, this upper reach of the setting offer two paths for visitors to follow as they explore. One of leads to a ladder draped over the edge of the plateau to offer a way down to a shoulder of rock arcing around the garden plateau. This forms another garden space with its own gazebo nicely separated form the rest of the setting to give a greater sense of intimacy / privacy, with treats and hot drinks available under its roof, exotic plants scattered among its flowers together with statutes, while trees provide shade and birds watch over the comings and goings of visitors.

The second path goes by way of steps to a larger garden space. this offers seating in the form of a bench floating under a cloud and a balloon holding aloft a seat for singles and couples (beware of the drop when standing up!), together with another table of treats and a Greco-Roman style gazebo where the 14 gifts for Valentine’s can be found, displaying the dates and times they will become available to Group members.

Beyond this area, another ladder descends to the second half (so to speak) of the lower shoulder of rock, which again offers companionable seating in two locations (and an easily missed swing if you are not paying attention!), together with a bridge spanning the gap to the smaller of the two islands.

Here, the setting is again split into various levels. Just off to the left on crossing the bridge, the island offers a curve of grass richly coloured by wildflowers, as it arcs its way to where water forms a curtain and pool as it drops from a rocky archway. As it does so, the path passes a table set for a tea party, although no individuals in hats or mice or caterpillars are in evidence –  just a pair of friendly rabbits :). Just before the waterfall and pool, a hint of magic is provided in the form of a bird perched on an upright post. Magical because if you wait just a few minutes, the bird will change its form and song.

The waters of the fall drop from the rocks forming the upper tier of this island, reached easily enough by a set of stairs. Here visitors can take a pony ride and receive a gift of said pony at the end. A trail winds around the plateau, passing all the points of interest, including statues, a pair of swings to ride, together with the opportunity for a picnic under the boughs of twisted trees and in the company of white peacocks. This trail ends in steps running down to another path and gazebo set at one end of another sweeping curve of garden.

A third ladder has been cast down from the north-eastern side of this upper space to offer a way down to perhaps the most secluded part of the gardens. This is where water drops down from the pool mentioned above to join with the flow of additional waterfalls as they combine into a large pool before tumbling over the edge of the island to fall away into the clouds below. Marked again by a colourful array of flowers and trees,  this area offers seating within another gazebo and a further swing suitable for solo sits.

Sable Hound Hollow – Romantic Reverie, January 2026

All of the above barely scratches the surface of all there is to be found here; Honey’s attention to detail means that everywhere are touches and details. These run from the mix of flower and plants – most conventional, some carrying a sci-fi or fantasy twist; the local wildlife, some of which might be easily missed (like the weasel peeping out of a hollow log); the floating lanterns, and more.

Both romantic and serene, the island of Sable Hound Hollow make for a relaxing and visually engaging visit.
