SL15B: fifteen years and counting!

The SL15B Cake Stage

The first part of the celebrations for Second Life’s 15th anniversary opened on Sunday, June 17th, when the SL15B Community Celebration regions opened to the public.

Events within the 24 regions will run from Sunday, June 17th through until Sunday, June 24th, with the Big Day, marking the original opening of Second Life to the public at large, far back in June 2003, taking place on Saturday, June 23rd. After the main celebrations, the regions will remain open for visitors from Monday, June 25th through Sunday, July 1st, although there will be no formal events during this period.

The SL15B (animated) Serpent Stage

As befitting a 15th anniversary, the theme for this year’s community celebration is crystal, so expect to see a good few builds within the regions reflecting this – and possible watches and timepieces as well, given these are often gifts associated with 15th anniversaries.

Throughout the week of festivities, there will be much going on: music, dancing and performances at the various stages found within the regions; talks and presentations within the auditorium – including the now-familiar Meet the Lindens events, of which more anon, and some of the exhibits built be SL residents and found within the regions may also play host to events of their own.

The SL15B Welcome Area 1 and Welcome Area 2

The festivities bring together the use mix of resident-build exhibitions and SLB infrastructure builds – with the latter this year being provided by Mikati Slade – Cake Stage; Walton F. Wainwright (Faust Steamer) -Serpent Stage; Anthony (ADudeNamed Anthony) – Auditorium; Ancient Mole – Crystal Rotunda Stage and Welcome Area: and City Builder (Lim Pikajuna) – Stage North.

As well as these, there are special features, such as the Tapestry of Time, tracing Second Life’s History from 2003 to the present; people can also pay a visit to the original Cornfield – the Sin Bin of early Second Life, and tour Bear Island, which makes a return to SLB celebrations for all lovers of Linden Bears. Plus the ever-popular SLB Big Hunt and the pod tours and very much a part of the festivities.

Meet The Lindens

This year, Meet the Lindens will talk place between Monday and Friday, at 12:00 noon SLT at the SL15B Auditorium. The participating Lindens this year include:

  • Xiola Linden – Monday, June 18th.
  • Patch Linden and Kiera Linden – Tuesday, June 19th.
  • Ebbe Linden – Wednesday, June 20th.
  • Grumpity Linden and Oz Linden – Thursday, June 21st.
  • Brett Linden  – Friday June 21st.

Appreciating the great outdoors in Second Life

Zion National Park; Inara Pey, June 2018, on FlickrZion National Park – click any image for full size

Zion National Park is an ambitious, two-region stretch of parkland designed by Alexxis Foxdale Judge Firecaster. It offers a look and feel of some of the great national parks of north America – most notably Yosemite, given the reproduction of the Mariposa Grove – and presents a lot to see and explore.

A visit starts on the north side of one of the two regions making up the park. This features a park lodge and a camping ground (parcels available for rent), looking to the north over open water and a distant range of mountains. A dirt track runs between the lodge and camp site, pointing west towards a narrow cleft between high shoulders of rock, and east to run almost parallel to the water’s edge and between the massive trunks of huge Sequoia-like conifers.

Zion National Park; Inara Pey, June 2018, on FlickrZion National Park

Which route you take is entirely up to you – but if you have a wearable horse, you might want to add that and take to riding while exploring (a riding horse rezzing system would be a nice addition to the park). The route west will take you through the rocky cleft to where another body of water await, overlooked on both sides by a rugged landscape that, to the south, climbs towards distant green peaks.

Here the track swings by a small lodge were visitors can take a log ride around the lake – just wait for a boat to automatically rez ready to depart as one returns and de-rezzes. The ride will take you east along the lake, under the tall trestles of a cliff-top bridge spanning the water, and back around to the west before returning you to the little lodge. Or, if you prefer, you can follow the track to where it climbs up into the hills, switching back on itself as it does so, to arrive at a high café abuts the steeper slopes of the (off-sim) mountains).

Zion National Park; Inara Pey, June 2018, on FlickrZion National Park

If you opt to go east from the landing point, the track will take you by twist and turn, passing the single permanent private residence to be found here, to where it again climbs up into the rocks and hills of the park. This leads the way past cliff-edge seating areas overlooking waterfalls, paths to hidden tunnels, and a climb up to a peak where a hang glider can be rezzed and you can take to the air to appreciate the park from overhead.

The high paths rise and fall, twist and turn, cross canyons and water by way of bridges, descend to the edge of bubbling streams  and pass through mine-like tunnels to link up with one another, allowing visitors to fully circumnavigate the park, often just a few short steps from where the regions end and the off-sim mountains begin – a relatively seamless join that gives Zion Park a huge amount of additional depth, vastly increasing its national park like feel.

Zion National Park; Inara Pey, June 2018, on FlickrZion National Park

Wild life is to be found here in abundance – the trees are rich in bird song, bears grumble and roam,raccoons raid litter bins and get up to other mischief, wolves bask in the sunlight and elk graze or drink cautiously from the banks of streams. Going by the chap out on the waters of the lake and the cormorants on the shoreline, fish are in abundance in the waters here as well. There could perhaps be a few more places to sit and enjoy more of the many views to be found within the regions, but this is a minor point; as noted, if you do have a wearable horse to ride, this is a place where you can put it to good use and appreciate the views.

All-in all, Zion Park is a rich environment which demonstrates just how much can be done when working with Homestead regions. The default Windlight settings perhaps don’t do the landscaping full justice – I’d certainly recommend playing around with any you have installed on your viewer to find something more suitable and warm. When exploring, keep an eye out for the information boards, and the way down to the subterranean lake. The former are a worthwhile read for those unfamiliar with American national park heritage, and the latter takes a little finding – but a visit cannot be said to be complete until you do 😉 .

Should you enjoy your visit to Zion National Park, please consider a donation at the lodge alongside the landing point to help ensure the regions remain for future visitors to enjoy – and for additional visits of your own as the mood takes you!

Scarlet studies, humans and aliens, and an invisible man

Seanchai Library

It’s time to highlight another week of storytelling in Voice by the staff and volunteers at the Seanchai Library. As always, all times SLT, and events are held at the Library’s home at Holly Kai Park, unless otherwise indicated.

Sunday, June 17th

13:30: Tea-Time at Baker Street

Caledonia Skytower, Kayden OConnell and Corwyn Allen return with a Seanchai favourite: Tea-time at Baker Street. This time they are going right back to the roots of the legend, and the case which first introduced the world to Doctor John Watson and the renowned Consulting Detective, Mr. Sherlock Holmes.

study-in-scarletA Study in Scarlet was written in 1886 as a full-length novel by Sir Arthur Conan Doyle and published the following year. It is actually one of only four novel-length stories Conan Doyle penned about Holmes and Watson in the original canon (the remaining 56 tales of their adventures are all short stories). As it was the first time the two had appeared in print, part of the story was used to establish each of them, and how they met.

It is 1887, and Doctor John Watson, invalided out of the British Army after being wounded in the Battle of Maiwand during the Second Anglo-Afghan War (1878-1880), has returned to London where he is seeking accommodation. After bumping into an old friend, Watson finds himself being taken to St. Bart’s Hospital, where he is introduced to a stranger carrying out a laboratory experiment. On shaking Watson’s hand, Sherlock Holmes immediately perceives that he has recently returned from Afghanistan, and thus Watson first experiences Holmes’ remarkable deductive abilities – although quite how Holmes came to his conclusion remains a mystery. After a short conversation, he agrees to join Holmes in moving into a flat (apartment) at 221B Baker Street, where they’ll split the rent.

In the story, it is actually several weeks before Watson learns of Holmes’ rather unusual chosen profession. When told, he remains initially dubious until Holmes gives a practical demonstration of his powers of observation and deduction, using a messenger from Scotland Yard as his subject. The messenger has come with a request for Holmes’ assistance; Holmes is at first reluctant to heed the call,  but Watson urges him otherwise. So it is that they set out on their first adventure together, one involving poison, a double murder in London and a bitter tale of love, loss and revenge from America.

18:00 Magicland Storytime – Mrs Piggle-Wiggle

Mrs. Piggle-Wiggle lives in an upside-down house and smells like cookies. She was even married to a pirate once. Most of all, she knows everything about children. She can cure them of any ailment. Patsy hates baths. Hubert never puts anything away. Allen eats v-e-r-y slowly. Mrs Piggle-Wiggle has a treatment for all of them.

The incomparable Mrs. Piggle-Wiggle loves children good or bad and never scolds but has positive cures for Answer-Backers, Never-Want-to-Go-to-Bedders, and other boys and girls with strange habits.

Join Caledonia Skytower at the Golden Horseshoe in Magicland Park, as she reads from Betty MacDonald tales of Mrs. Piggle-Wiggle.

Monday, June 18th 19:00: Protector

Phssthpok the Pak had been travelling for most of his thirty-two thousand years. His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years previously.

Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days — Brennan figured to meet that ship first…

He was never seen again. At least not by those alive at the time.

Wednesday, June 20th 19:00: Written in the Sand

Images and Thoughts from the Seashore with Ktadhn Vesusino.

Thursday, June 21st: The Invisible Man

Oh! – disillusionment again. I thought my troubles were over. Practically I thought I had impunity to do whatever I chose, everything – save to give away my secret. So I thought. Whatever I did, whatever the consequences might be, was nothing to me. I had merely to fling aside my garments and vanish. No person could hold me. I could take my money where I found it. I decided to treat myself to a sumptuous feast, and then put up at a good hotel, and accumulate a new outfit of property. I felt amazingly confident, – it’s not particularly pleasant to recall that I was an ass.

– Griffin, the Invisible Man

Join Shandon Loring as he delves into the classic tale by H.G. Wells of Griffin, a man already consumed by a desire to have power and fame, who finds a way to make himself invisible to the rest of the world – but not the way to become visible again.

The results do not go in his favour, heightening his bitterness and encouraging him to think only in terms of wreaking havoc as his bitterness grows deeper and his desire to revel in the absolute lack of conscience, to commit crime and instil terror, grows to the point of fanaticism… Also presented in Kitely (hop://

2018 SL project updates 24/3: TPVD meeting

Woods Club; Inara Pey, June 2018, on FlickrWoods Clubblog post

The majority of the following notes are taken from the TPV Developer meeting held on Friday, June 1st 2018. A video of the meeting is embedded below, my thanks as always to North for recording and providing it.

SL Viewer

  • The Pálinka  Maintenance RC updated to version on Friday, June 15th.
  • The Bakes on Mesh project viewer updated to version on Thursday, June 14th.

The rest of the current SL viewer pipelines remain as follows:

  • Current Release version, dated May 31, promoted June 1 – formerly the Love Me Render Release Candidate – No Change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • 32-bit Windows Unloop RC viewer, version, dated June 5 – specifically for 32-bit Windows users caught in the 64-bit install loop (see here for more). Otherwise, the viewer is functionally identical to release version
  • Project viewers:
  • Linux Spur viewer, version, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

[13:07-13:30] The 360 snapshot viewer has been stalled pending other work (such as support for uploading 360 images to Second life Place Pages) and for resources to work on it – but it has not been forgotten.

Upcoming Viewers

  • [4:15-4:36] Voice update: there should be a new Voice RC viewer arriving, hopefully in the next two weeks. This will contain a new SL voice updated from Vivox.
  • [5:56-6:26] Texture caching: a project viewer re-working texturing caching should be appearing soonTM. This viewer (and the work related to it) is currently on hold pending the Environment Enhancement Project (EEP). When it does appear, the Lab is confident it will make a noticeable improvement to viewer performance.

Animesh Mini-Update

Please refer to my CCUG meeting summary for more on the status of Animesh.

[0:24-2:46] The Lab is aiming to try to get Animesh deployed to a release candidate channel on Agni (the Man grid) during week #25 (week commencing Monday, June 18th, 2018). It is not 100% certain there will be a deployment but, according to Oz, if it does go ahead, it will likely be a part of the RC deployment to the BlueSteel channel. Region holders wishing to test Animesh can request their region be moved to the required RC via a support ticket.

Note that the viewer supporting Animesh will remain at project release status for the time being.

[38:28-42:40] discussion – voice and chat of the Animesh 90-degree rotation issue. Again, all see my CCUG meeting notes, linked to above.

Region Crossings

[4:42-5:50] Work on trying to improve region crossings on the simulator side of the equation is continuing. The messaging changes as a result of this work  are being ported to the SL viewer, and should appear in a future Maintenance branch of the viewer, although the messaging updates themselves are not expected to have any real effect on improving region crossings from a viewer perspective.

The simulator changes are being handled one at a time, and will be appearing in simulator RC updates over the course of the next few months.

In the meantime, and as reported in my Simulator User Group updates (see here for an example), user Joe Magarac (animats) has developed a viewer-side update to help correct some of the region crossing issues within the viewer, particularly in relation to “partial unsits”. His work is likely to be featured in the upcoming Firestorm release, and I’ll have more on that in my review of that release. It’s not clear if these changes have been contributed to the Lab (or if they would be accepted if they have).

Global Experiences

[14:58-17:45] There have been concerns that the roll-out of grid-wide experiences will mean automatic opt-in to such activities, rather than consented opt-in. This will not be the case: grid-wide will function the same as current region / parcel experiences – consent will need to be granted via a dialogue box. Only experiences developed by Linden Lab may have automatic opt-in, although none of the Lab’s experiences to date use this, and there are currently no plans to deploy any that do.

The only difference with grid-wide experiences and current experiences is that the land owner doesn’t have to explicitly allow grid-wide experiences (it will – I understand – instead be a case of land owners opting out of grid-wide experiences if they don’t want them on their land).

There has also been a request to make experience dialogues when requesting the ability to take control to be friendlier  / more informative on the grounds that people are scared of them.

[23:30-37:00] There is an extended discussion (mostly text) over unintended consequences of experiences when combined with tools such as avSitter (and / or RLV), and the potential for abuse. This includes a discussion on how to make it easier for users to discover what is acting on their avatar through the viewer UI (and the problems in trying to do so).

In Brief

  • [3:28-3:58] https move – work is progressing on moving all of the SL web services to https: – however, this work has been more of a background task of late while the web services team work on other projects. So, not time frames on when the various services still to be moved will do so.
  • [8:44-9:58] SL wiki edit rights / JIRA comments rights: because of issues with spam bots, etc., both the SL wiki and the SL JIRA has been locked from casual editing (wiki) / making comments on reports (JIRA).
    • If you have a valid need to edit SL wiki pages, submit a support ticket with a request for edit rights. All requests are reviewed and access granted on the outcome of said review.
    • If you have a valid reason to want to comment on SL JIRA reports, you should e-mail a request with your SL user name and why you are requesting access to
    • Note that the JIRA lock does not prevent people from raising JIRA bug reports and feature requests.
  • [22:48-23:28] The Read Off-Line Messages Capability: there have been a couple of issues in handling Friend and Group requests received while off-line. These are being addressed server-side, and it is hoped the code will be with QA in week #25 (commencing Monday, June 18th, 2018), and will hopefully be deployed shortly thereafter.


3D surrealism in Second Life

Classical and Surreal Sculpture

Quite by chance I stumbled across Classical and Surreal Sculpture, an open-air exhibition of works of surrealism taken from famous exponents of the genre and rendered as 3D models by MADD (maddomxc Umino). It’s a small place, and the setting a simple parcel field covering just 3072 square metres.

Within this space, MADD has reproduced surrealist works of art by some of the more famous exponents of the genre, including Constantin Brâncuși (1876-1957), Umberto Boccioni (1882-1916), Max Ernst (1891-1976), René Magritte (1898-1967), Walter Mac Mazzieri (1947-),  and Masaru Shichinohe (1959-), together with assorted reproductions of a number of sculptures,- most notably perhaps Prométhée (Prometheus) by Nicolas-Sébastien Adam (1705-1778).

Classical and Surreal Sculpture

Some of the more famous pieces by these artists are offered: Magritte’s The Lovers, for example, or Ernst’s L’Ange du Foyer (Angel of the Hearth) and Surrealism and Painting. Despite the small space, all of the pieces on display are set out such that the field doesn’t feel at all crowded, and a couple are presented with copies of the original 2D art on which they have been based. In the case of Surrealism and Painting, this has been done quite humorously – the sculpture is painting the image upon which it is based (rather than the piece the original is painting).

All of the pieces on display are offered for sale – a point that did admittedly leave me a little twitchy around issues of copyright, notably – but not exclusively – around the pieces based on Mazzieri and Shichicohe’s work.  However, and particularly in the case of the reproductions of the 2D art pieces, these are very well executed pieces, and while I’m not exactly a huge lover of surrealism (although I do admire Magritte’s work), this little corner of Second Life makes for an interesting visit.

2018 SL project updates 24/2: CCUG meeting summary w/audio

MindPillars, a Scottish themed Sim; Inara Pey, May 2018, on FlickrMindPillars, a Scottish themed Simblog post

Updated on June 15th: to include planned RC channel for Animesh deployment – see notes below. 

The following notes are taken from the Content Creation User Group (CCUG) meeting, held on  Thursday, June 14th, 2018 at 13:00 SLT.  These meetings are chaired by Vir Linden, and agenda notes, etc, are usually available on the Content Creation User Group wiki page.

Note that the audio presented here may not be in the exact order of discussion during the meeting; as subjects were at times returned to following their initial discussion, I have attempted to bring together key points of discussion by topic / subject matter. Also, please note that audio drop-out when Vir is speaking appears to be an ongoing problem at his end.


Project Summary

The goal of this project is to provide a means of animating rigged mesh objects using the avatar skeleton, in whole or in part, to provide things like independently moveable pets / creatures, and animated scenery features via scripted animation. It involves both viewer and server-side changes.


Current Status

It now appears that Animesh could be arriving on the server-side release channels on the main (SLS) grid as early as week #25 (week commencing Monday, June 18th, 2018). There are caveats to this: the status of issues with the viewer being one of them – there are certain issues the Lab is focused on, which they would ideally like to have some fix / workaround in place for prior to deploying the Animesh simulator code to Agni.

Update: At the TPVD meeting on Friday, June 15th, Oz Linden indicated that if the Animesh simulator code is deployed to an RC in week #25, it will most likely go to BlueSteel.

Current Viewer Issues

Encroachment / Position / Offsets: this is to ensure that the visual position of an Animesh object is not too far offset from its position as calculated by the simulator (e.g. using things like animation offsets to alter the visual position of all or part of an object). The fix for this is to force the bounding boxes for all joints and the meshes attached to them to remain within a specified distance – most likely 3 metres, although this is still TBC – from the location where the simulator has calculated the object should be.

This update should be in the next update to the Animesh project viewer, and will also utilise new infrastructure on the back-end to allow smarter tracking of the bounding boxes for rigged meshes. This be being done by tracking bounding boxes on a per joint basis, and then transforming them. While it can take a “noticeable” mount of time to do this, Vir’s belief is that it doesn’t unduly impact performance, although if it does become an issue, it may be re-thought.

Concerns were expressed that this would limit the scaling of Animesh creations. Vir states this shouldn’t be the case – the restriction is not ties to scale, but to position. So, for example, a dragon could still be 60 metres in length / height,  but the encroachment fix would mean where it appears in people’s viewers cannot be offset more than 10 metres from where the simulator calculates its actual position to be as a static mesh.

Z-Offset Height Setting: until now the z-offset height setting that can be specified when uploading a mesh to Second Life has been ignored when using meshes with it set to Animesh objects (the offset only works when the mesh is attached to and avatar).

It is hoped an update to fix this will be in the next project viewer update, which should appear before the server-side Animesh code arrives on an Agni RC channel.

Rigged Mesh Level of Detail / Bounding Box Issues: (BUG-214736) – Essentially, attachments on avatars swap their LOD models as if they were scaled to the overall avatar bounding box.

This is a long-standing issue which Graham and Vir Linden are working on, but a fix is unlikely to be available prior to Animesh arriving on Agni.

Broken Rotations Issues:

  • In one (BUG-139251), when some static mesh objects are converted to Animesh, the visual mesh is rotated through 90 degrees when seen in the Animesh viewer, but the physics mesh isn’t, leaving it perpendicular to the model. This is possibly an orientation issue, with the viewer expecting the mesh to be aligned to +x=forward – which not all mesh modelling tools follow.
  • The second problem is that when linking a series of objects into a single Animesh, then are visually located where the avatar skeleton supporting them is located, but the physics shapes remain in the original location of the objects prior to linking / converting.

The recommendation here (for the time being) is that Animesh objects should have a non-mesh root object, and associate any physics representation to that non-mesh root object.  This should hopefully eliminate the current issues and help ensure that any mesh being propelled via scripts in the root object will move in a predictable manner (.i.e. moves forward when driven forward by a script).

Other Issues

Additional bugs: the above are not the only bugs being looked at, but they are the ones causing the most concern due to the risk of behavioural issues / changes they might cause, together with perceived content breakage, when Animesh starts being deployed to the Main grid. Other issues, which are not seen as having so direct an impact will continue to be looked at ad hopefully resolved as Animesh is tested on the Main grid, together with any other issues which may come to light.

GLOD: there is concern that the global LOD values set by the mesh uploader when creators don’t specify their own custom LODs incorrectly encourages poor optimisation, by rewarding those so decrease the calculated LOD values with lower LI post-upload. The feeling is that the reverse should be true. It’s anticipated that Project ARCTan should help to address this.

Bakes On Mesh

Project Summary

Extending the current avatar baking service to allow wearable textures (skins, tattoos, clothing) to be applied directly to mesh bodies as well as system avatars. This involves server-side changes, including updating the baking service to support 1024×1024 textures, and may in time lead to a reduction in the complexity of mesh avatar bodies and heads.

This work does not include normal or specular map support, as these are not part of the existing baking service.


Current Status

A new Bakes on Mesh project viewer arrived on Thursday, June 14th. Version includes the new “universal” wearable types corresponding to the 5 new bake channels. These are:

  • LEFT_ARM_TATTOO – bakes to the mesh left arm.
  • LEFT_LEG_TATTOO – bakes to the mesh left leg.
  • AUX1_TATTOO – creator definable layer / channel.
  • AUX2_TATTOO – creator definable layer / channel.
  • AUX3_TATTOO – – creator definable layer / channel.

Note that none of these additional wearables can be applied to the system avatar mesh; which continues to use the original six bake channels.

It’s also not clear if alpha layers can mask these new channels at present. If not, that Vir agrees it is something that should be looked at.

Other points of note:

  • There are no plans to extend Bake on Mesh to allow the use of wearable on non-wearable objects. This is because Bakes on Mesh uses the avatar bake service, which is not geared to apply wearables to in-world objects sans an avatar shape.
  • There is no time frame for Bakes on Mesh deployment at the moment; the project is still in the process of being developed, tested and refined with the help of content creators.
  • There is no updated on any form of scripted control for Bakes on Mesh. It hasn’t been ruled out, but no work is currently being done for scripted support.

In Brief

  • Mesh uploader cost formula / calculations: there have been requests to offer a clearer explanation of mesh cost calculations through something like a clarified wiki page. In terms of Animesh, providing guidelines on potential cost is difficult, as the actual conversion of a mesh to an Animesh takes place post upload.
    • One suggestion to help estimate Animesh costs is to add an Animesh model type to the drop-down list of object types in the mesh uploader.
  • Bento .BVH animation issue: the .BVH format allows for custom joint names for animations in addition to the default joint names. One such custom schema is to prefix joint name with “avatar_”. However, it has recently come to light that while the use of “avatar_” on pre-Bento joints works, trying to upload animations using any of the Bento bones prefixed with “avatar_” results in either an error message on upload (the SL viewer) or the animations uploading, but then being ignored on playback (tested with Firestorm). A JIRA bug report has been requested for this.
