Kirsten’s Viewer 1725: delving into the Arcane

Thursday, September 28th, 2022 saw the release of Kirsten’s Viewer S23 Build 1725 (what a pity build 1701 was a preview – it would have been Enterprise-ing to have a full release like this with all that is packed into it, go out with that ionic number! 😀 ).

While there was an earlier preview release, Build 1725 (initially 1705) – code-named Arcane – marks the first full release of Kirsten’s viewer in over a year – and brings to culmination a lot of hard work on Kirsten’s part in completely overhauling the viewer from stem-to-stern as well as incorporating the latest updates from Linden Lab.

Linden Lab Updates

Given the span of times between this release and the last, there have been numerous de facto viewer releases from the Lab such that listing them all here would simply read as a telephone directory of viewer version numbers and names. However, among that list there are some significant releases worth referencing as now being reflected in Kirsten’s Build 1725:

  • LLModalDialog() crash hotfix viewer, version, September 2022
  • Profiles Viewer, version, August 2022.
  • Performance Improvement viewer, version, May 2022.
  • Multi-Factor Authentication (MFA) viewer, version, May 2022.
  • Cache+ 360 Capture viewer, version, December 2021.
  • Viewer UI updates, version, June 2020.

All of which means that Kirsten’s viewer is bang-slap up-to-date with the Lab’s official release viewer code-base at the time of writing this overview.

For many, the chief updates in the above list will be the Performance Improvements, which (as with other viewers incorporating the Lab’s improvements) bring a significant FPS boost to most systems – notably with ALM enabled, but frequently with ALM+Shadows enabled); together with the 360-degree snapshot capability.

Performance Improvements / Changes

The Performance improvements contained within Kirsten’s 1725 actually break down into two categories:

  • The primarily under-the-hood improvements from Linden Lab which come via the Performance Improvements viewer as defined above,
  • The Graphics Improvements developed by Beq Janus and first released in Firestorm 6.5.3 in March 2022. These were submitted to Linden Lab and have been incorporated into the Performance Floater / Auto FPS t viewer, which at the time of writing this article was at project viewer status, and from which they have been pulled into Kirsten’s S23 1725.

Those wishing to take a deeper look at the Graphics Improvements floater and its options can do so via my Firestorm 6.5.3 review – but please note that while the functionality present within Firestorm is largely the same as for the official viewer /Kirsten’s viewer, the layout of the floater is slightly different. For completeness, the following is just a brief outline of the floater and its panels as found within the official viewer / Kirstens viewer:

The Firestorm-developed Graphics Improvements floater, as found with Kirsten’s Viewer (and the Lab’s Performance Floater / Auto FPS viewer)
  1. Your current frame rate, which can be adjusted through changes in the Graphics Settings panel. Note that my FPS is shown as running at a maximum of 60 FPS as I have Vsync enabled, which limits frame rates to the screen refresh rate (60 Hz).
  2. Displays the most commonly-used graphics settings (but not all – the Vsync option, for example, is absent and must be accessed via Preferences→Graphics) which can impact frame rates.
  3. Lists all the avatars your viewer is currently rendering, and presents the time is takes to render them in microseconds (”s – a millionth of a second).You can use this panel to select individual avatars and select whether or not they are always fully rendered or never fully rendered.
  4. Provides a breakdown of your avatar’s attachments and their render time / cost, and allows you to remove “laggy” items.
  5. Provides a breakdown of your avatar’s HUD attachments and their render time / cost, and allows you to remove “laggy” items.
  6. Presents the “Auto FPS” capability (several of the options found in the top bar of the Firestorm version of the floater as described in my review above) together with distance settings for rendering avatars in full detail and between which the auto-FPS will attempt to function.

Kirsten’s Viewer Updates

Build 1725 also includes a lot of changes from Kirsten as well. This can be split between the “visible” and the the under-the-hood, which together add up to a lot of work on Lee’s part to completely overhaul the viewer’s code and add multiple subtle but worthwhile changes.

The visible updates include:

  • Use use of gradients in floaters an panels to add a “softness” to them which helps them feel more a part of the viewer and the rendered scene behind, rather than sitting like a floating rectangle completely obscuring the view beyond.
  • Subtle, but appreciable updates to some – but not all – of the toolbar button icons.

  • A refactoring of the AO floater to clean-up issues of buttons overlaying text within the panel.
  • 1725 offers three new viewer skinning options:
    • Linden – speaks for itself, for those who prefer the look of the official viewers.
    •  Pewter – the default, and a really nice take on the colour of the odd 1.23.x viewer series offering a soft pewter blue which is easy on the eye.
    • Jinx – a more lavender / purple finish semi-mindful of Kokua without replicating it.

Film Menu

Kirsten’s Viewer film menu
The Film Menu is a new menu option to Kirsten’s Viewer which is likely to be useful to photographers and machinima makers – and possibly to those who have the Space Navigator (SpaceNav) 3D mouse available for use with SL.

In short, this brings together options from other menus and Preferences, as will as supplying some custom options, designed to make recording machinima / taking photos easier. These range from the basic hide / show UI elements / HUDs through to adjusting shaders and those nifty options for adjusting how your SpaceNav mouse responds / influences avatar behaviour.

This menu may not be as comprehensive as the likes of similar options from in Black Dragon or the PhotoTools UI option within Firestorm, but it is still a good selection of functions and toggles that can be easily called up when filming / photographing a scene  – although as a photographer myself, I’d perhaps like to see a few additions to make the menu a little more usable to those of us (the majority?) who prefer to take stills shots (e.g. the ability to de-render all avatars from a landscape shot, for example). But this is a minor point.


The core amount of work carried out in this build has been the merging with the latest LL code-base, and a major overhaul of the code by Kirsten, as noted in the release description:

Anaglyph Render refactored … System detection totally rewritten to interrogate kernel (not registry or using manifests). Days and Days removing old code and going line by line improving performance. And I seriously mean that analysing each if/else statement and function for even the most minute tweak.
Finally, this is built with full optimisation and link time code generation.


Kirstens Viewer has always offered good performance and crisp rendering, and the incorporation of the Lab’s updates (and those modified from Firestorm), together with the work put in by Kirsten in refactoring the code means that S23 1725 is one of the slickest performing viewers  I’ve used – although I have little doubt it would not find favour among some SL users due to the lack of RLV or RLVa support, which is a shame.

On a personal note, I do like the new skinning options that come with 1725 – the “old” green default was to me a little too vibrant, whereas the Pewter is a lot easier on the eyes. However, I have been conflicted over the use of gradients on the drop-down menus. As  noted above, the use of gradients on floaters and their panels works well,  but their use in the menus might make menu options harder to see for those with vision impairments.

But, that said, there is no doubt that 1725 is an excellent update to Kirsten’s Viewer, and one that will hopefully put the viewer in a position where it an more readily keep pace with updates from Linden Lab & adopt new features (and those deemed suitable coming out of other TPVs) going forward.

Rapid update: Kirsten’s Viewer & Speedlight

Isla Caitinara via Kirsten’s Viewer

While viewer updates are always in process across the available TPVs and clients, I thought I’d take a brief delve into recent updates for a couple of those I tend to routinely follow – Kirsten’s Viewer and the Speedlight Browser / Android / iOS client.

Kirsten’s Viewer

Late February and early March have seen a burst of activity from KirstenLee Cinquetti, with three versions of the Kirsten’s Viewer being released in a rapid-fire succession, started with S23.6.1500 on February 23rd and running through S23.6.1525 (codenamed Valkyrie, dated February 27th) and then S23.6.1533 (also, I gather, Valkyrie, released on March 2nd).

Give it’s been getting close to a year since the last update (see Kirsten’s viewer: a return to active duty and Kirsten’s Viewer gains the client-side AO), these releases do not focus on new features so much on both catching-up with the Lab’s core code base (which appears to be currently still in progress) and a lot of under-the-hood house cleaning.

In particular, the code clean-up means that as from the S23 release, Kirsten’s Viewer discontinues support for Linux /Solaris/ OSX, and the viewer will be Windows-only. The reason for this is simple: time.

Why would I do such a thing? Its simply the realisation that keeping this thing maintained takes time, which is a rare commodity and focusing on a pure windows based solution without sifting through endless defines and endif’s not to mention the triple whammy cmake files or anything else for that matter makes life a heck of a lot simpler.

– KirstenLee on why Kirsten’s Viewer is now Windows-centric

A further benefit of this move, as Kirsten goes on to note, is that it also streamlines the Windows built process itself, through the integration of some of the build libraries into Visual Studio 2017 (now the core build tool for the Windows flavour of viewers), rather than relying on third-party libraries.

Given this focus, it appears the viewer has yet to get some of the more recent updates from the Lab, including:

  • Camera Presets (contributed to the Lab by open-source developer Jonathan Yap).
  • Mesh Uploader updates (contributed by open-source / Firestorm developer Beq Janus, with further modifications by the Lab).
  • Avatar “jelly doll” rendering improvements (via Vir Linden).

That said there are a couple of new additions to be found in preferences:

  • The return of the Midnight UI skin (Preferences → S23 Features → S23 UI Selection).
Kirsten’s S23 see the return of the purple “Midnight” UI skinning (viewer restart required)
  • The inclusion of the Controls Tab from the Lab’s Custom Key Mappings RC viewer, which allows users to assign specific key mappings to a range of viewer functions (Preferences Controls).
S23 incorporates the Lab’s custom key mapping options, which at the time of this review, were still at viewer release candidate status in the official viewer.

As  noted, these recent releases are more along the lines of maintenance work and under-the-hood changes that are vital to the viewer’s longevity and future ease-of-update, rather than intending to present significant user-facing updates.

But that said, and with this work now completed, it hopefully won’t be too long before options such as the jelly doll updates and Camera Presets appear within Kirsten’s Viewer  and it continued to recover greater parity with the Lab’s code base and releases.

Details on KirstenLee’s recent work on the viewer can be found on her blog, and the viewer can be downloaded here.


Speedlight, the browser / android / iOS client updated in mid-February, with updates for both Basic and Gold users.

Core updates (Basic and Gold):

  • Places search has been added.
Speedlight now includes the ability to search via region / parcel name (subject to location’s search listing)
  • SLURLs are now clickable with an ability to teleport.
  • Avatar maturity can be changed via the Settings → Maturity tab.
  • The Avatars page (dashboard) now displays the current location of your avatars.
The location of your avatar(s) is now listed on the Avatar dashboard page

3D World View Updates:

  • Walk auto-pilot: right-click or long touch on device screen at location to the walked to, then select Walk Here from the pop-up menu.
  • In-world object interaction (Touch): right-click or long touch object, and select Touch from the pop-up menu.
  • Revised interface for the world view, with improved rendering.
  • Gold 3D Word View Updates:
    • While in low-poly mode, touch any object to load a high LOD model.
    • Holding ALT+mouse will rotate camera around avatar (as with a viewer).
    • On-screen joystick can be turned on in 3D settings.
    • Stick avatars size adjusted to fit with real avatars in preparation for avatar rendering).

The core updates noted above further tune Speedlight’s ability to meet with many use-cases for those needing to access SL while away from a full viewer. As noted last time around, however, my personal view is that the 3D world view remains hit-and-miss – even on my PC using a browser, objects frequently fail to fully render and avatar movement can be unpredictable.

Whether this is just done to my being Basic / have a bad connection to the rendering pre-processing server, I’ve no idea; but if these issues are more endemic, then perhaps they might suggest that more more needs to be tweaked before full-scale avatar rendering is attempted.

In the meantime, Speedlight can be run via any browser via the Speedlight Website, or downloaded from either Google Play or the Apple Store (fee payble for the latter, with automatic Gold lifetime subscription).

Kirsten’s Viewer gains the client-side AO

On May 2nd, I wrote about the return of Kirsten’s Viewer and its return to active duty. In that review I noted that while what goes into a viewer is down to those who maintain it, it would be nice to see Kirsten’s adopt the client-side AO mechanism, as first seen in the Firestorm viewer.

Following that review, KirstenLee’s partner, Dawny Daviau let me know the AO system was being considered and then, just a couple of days later, she Tweeted that the viewer had been updated with the AO code.

Even as an inside joke, I was flattered that KirstenLee had responded so rapidly to both Dawny’s prompting and my comment.

Dawny’s Tweet

I understand from KirstenLee’s own comments that getting the AO code into the viewer wasn’t easy, what with the UI changes created by EEP – so kudos and thanks got to KirstenLee and Dawny for going ahead and integrating it. Given it did take a little crowbarring, it’s not surprising that the AO floater has a couple of minor of rough edges to it – but these do not prevent it from being used or cannot be easily fixed.

For those unfamiliar with the idea of a client-side AO, it allows the animations from an animation overrider system to run directly from the viewer without the need to wear a resource-gabbing scripted HUD. It takes a little setting-up, but once done, it’s easy to use – and has the further benefit of allowing you to use multiple AOs together without having to worry about swapping HUDS or including different outfit links to different HUDs.

Quick guide to the essentials of the client-side AO as included in Kirstens Viewer

The best place to get information on setting-up and using the client-side AO is via the Firestorm wiki. A couple of points should be noted here:

  • When first loaded, the AO floater may not display all of the AOs in its floater (e.g. all your stands might be listed, but none of your walks). If this happens, click the Reload button at the bottom of the AO floater to get them to list and run.
  • The UI scaling in the floater is a little off in this S23-1387 KV iteration, so it my need to be broadened to correctly display.

Neither of the above points impact the AO’s usability, and in my own tests, I had no issues with setting it up and using it.

Also note that the AO will create a folder called #Kirstens in your invention, which will contain a copy of the AO(s) you have selected for client-side use – do not delete this folder when using the capability!

As a long-time user of client-side AO capabilities (including loading it with more than one AO set), I’m clearly a fan of the capability. I like the freedom it gives, and the fact there’s no need to have screen real estate (however small) taken up by a HUD and, more particularly, the fact that texture RAM and script resources needn’t be taken up by the use of a HUD. So while this might be a “small” update, I think it to be worthwhile and – if you’re trying out Kirsten’s Viewer and haven’t used a viewer-side AO system, this is a good opportunity to try it out.

For those who do use the client-side AO, and might be looking to an alternative to (say) Firestorm for photography, the addition of the AO button and floater offers another reason for giving Kirsten’s Viewer a try out.

My thanks again to KirstenLee for responding to the request from Dawny and I!

Kirsten’s viewer: a return to active duty

Around a decade ago, a popular third party viewer (TPV) among Second Life photographers was Kirsten’s viewer, produced by KirstenLee Cinquetti (aka skilled coder Lee Quick).

At the time, it pushed hard to make the graphical appearance of SL rich and deep. It was also the first TPV to experiment with analgyph 3D, far back in 2011, long before “VR headset” was in common use.

Sadly, development of the viewer drew to a close in late 2011 as a result of personal circumstance (some of which is charted in these pages), although KirstenLee kept dabbling with it on-and off (such as returning to the S19 UI version and updating it in in 2013, and keeping pace with significant viewer updates from the Lab, such as Bento for the S22.x (current UI) version in 2017).  Now – and as pointed out to me by Austin Tate – the viewer is more formally back, KirstenLee having completed the self-certification required to have the viewer once more added to the Lab’s Third Party Viewer Directory.

Available for Windows, the updated Kirsten’s Viewer is bang-slap up-to-date, in that it is built on the most recent release of the official LL code base (release at the time of writing), and so includes the viewer 3.x+ UI, and all significant updates from the Lab up to and including EEP, the Environment Enhancement Project, although as Kirsten noted with it’s release, some tweaks might still be required.

Kirsten’s Viewer is EEP capable

KirstenLee refers to the viewer as something of a “hybrid”, and when approaching it, it is as well to keep this in mind. “Hybrid” is this case is a reference to the fact that while it is based on the core LL code base, the viewer also pulls in elements from what might be LL project viewers (and so not necessarily ready for “prime time” use), and from other TPVs. In doing so, the focus is very much on code that improves stability / performance.

I tend as a rule to keep any feature or alteration within the existing code base and not add extras which cannot be integrated into the standard source. I also use LL code style and naming conventions.

– KirstenLee, discussing Kirsten’s Viewer

In this regard, the viewer is also described as being “aimed specifically at experienced users, with emphasis on the visuals.” This is not so much to put people off, but to underline the fact that use of the viewer comes best if you have an understanding of the more esoteric aspects of viewer use – such as clearing caches and settings from any prior versions when installing a new version (aka, performing a “clean install”). Such capabilities are not hard to grasp, and can be found documented in various locations.

Given the S23.x release is based on the latest LL code base, you can comfortably expect all of the major Lab updates to be present, as noted, and may from time-to-time include elements from upstream of the release viewer (as with the Legacy Profiles, again as mentioned above). It also pulls some updates from TPVs like Firestorm; however, those familiar with the latter should not expect Kirsten’s Viewer to expose debugs or offer viewer-specific capabilities to anywhere near the same degree – that’s not the point of this viewer (although that said, it would be nice to see Kirsten’s adopt the client-side AO mechanisms, simply because it is available in several TPVs and used by many people as a result).

Kirsten’s Viewer includes the upcoming re-integration of viewer-based profile panels – which includes the profile feed from the web, and currently found in the Lab’s current Legacy Profiles project viewer

Given this, the viewer’s Preferences and Tool Bar options are pretty must as found in the official viewer, with just a trio of differences in the the former. The Move & View tab, for example, includes additional sliders for camera movement  – lag, smoothness zoom time – again in keeping with the ideals of photography / visuals. Further, the Set-up tab does not include the auto update options, for reasons KirstenLee also explains:

I do not use the Linden auto build system. I host all the build libraries because I occasionally work on those in concert with the viewer code. It allows for much finer control over the entire process. I have a tendency to do custom compilations with different tool-sets which is something an official client would never do, for reasons of the broadest compatibility with the consumer.

– Kirstenlee, discussing Kirsten’s Viewer

Thirdly, Kirsten’s Viewer includes a custom Features tab (called S23 Features in the current release, although this will doubtless increment to match future versions). This is again camera / visuals related, and includes the option for running the viewer in analgyph mode can be found.  This includes sliders for adjusting the analgyph 3D view to account for eye separation and focal distance.

The Features tab in Kirsten’s Viewer is where you can find the analgyph options, for those with analgyph glasses

Should you have analgyph 3D glasses and use the option, the following points should be noted:

  • Activating it will disable the viewer’s Advance Lighting Model (ALM) shaders – so shadows, ambient occlusion and depth of field will all be disabled.
  • Toggling analgyph mode off will not automatically re-enabled ALM, you must do this yourself from the Graphics→Advanced Settings floater.
  • If you log-out with the analgyph option enabled, it will be disabled automatically on logging back in, but again, ALM + options will remain disabled until turned back on.
  • If you use a 3D mouse such as SpaceNavigator, you may find activating the analgyph capability will severely alter default 3D mouse movement. As the overall defaults for the SpaceNavigator (Move & View→Other Devices) were not altered and given I don’t actually have analgyph glasses to make it worthwhile, I confess I did not fiddle with settings to see if the issue could be corrected.

It may seem odd in “bringing back” a viewer after so long, but there are reasons for it, again as KirstenLee notes:

Its a matter of public record as to how development ended, a perfect storm of circumstances made continued work on it impossible. But as with all things time is a great healer. Besides after nearly 16 years of SL I find myself enjoying my in world life. And have the luxury of  a good work balance and a happy and healthy home. So while the sun shines make hay 🙂

For my part, and while I’ve not not driven the S23 release hard or far, I can only say its good to see Kirsten’s Viewer back on the active list once more. While it was never my main viewer, it was a go-to viewer for me for photography. And while it may only be subjective, it does seems to add more depth to EEP skies than I’ve noted with the official EEP viewer – the stars seem to “twinkle” more noticeably.

It’s always tempting to offer a list of what a viewer “could” or “should” have, particularly if coming from something like Firestorm – but the point of TPVs are that they are not meant to all provide the same things. With its emphasis on visuals, performance and stability, Kirsten’s Viewer addresses a specific set of goals and as such, has – and likely will have – only the tools it needs to achieve that, my own earlier comment on the client-side AO above notwithstanding.  As such, I’m looking forward to seeing the viewer’s progress, and reporting on it.

What dreams may come: Kirstenlee further updates S19

kirstensKirstenlee Cinquetti has issued a further update to the S19 version of Kirsten’s Viewer – version S19 1.19.4 (407). Released on Thursday May 16th, 2013, the update primarily fixes a nasty cache crash when user settings and local cache are manually deleted.

There have been a lot of questions as to why the S19 (v1-style) viewer from Kirsten’s stable is being updates rather than the S22/S23 viewers. In a blog post accompanying the release, Kirsten/Lee gives an answer:

So I guess the most pertinent question is why? It is probably the most pointless one to answer also.

But lets just take a wild stab at it!

I need to be in SL occasionally so I need a viewer (Duh), V2 is dead sorry S22 it was fun, V3 is well lets just say it’s not my cup of tea. I could just download someone else’s viewer but thats not what I want.

I LIKE S19 it was and still is quick, its code in comparison to newer clients is simpler it has much more modest hardware demands I can merge from many sources more rapidly etc, etc, etc..
It ticks all my boxes, on a more personal note it’s NOT limited to Second Life.

That is important to me, so it may have bugs, it may not compile on macs very well… sorry.

But if I wish to drift around SL or jump into Opensim I can.. anyway hope that kinda answers some of my motivations, and why I share the corresponding installer.

As mentioned in my last piece marking the “return” of the S19 viewer, and people shouldn’t anticipate routine updates and improvements; as Lee indicates in his bog post, this viewer has been updated and is being tweaked purely to suit his needs – and rightly so.

A couple of notable changes have been made since version S19.1.19.4.(404), the last version I used. Preferences have been moved from their “traditional” location in the File menu to appear under the S19 menu, and Depth of Field (DoF) has been added to the Graphics tab, in a dedicated sub-tab.

DoF is back!
DoF is back!

Sadly for me, I’m unable to test DoF, as deferred will not run on my hardware set-up, no matter how I fiddle with AA (which was Lee’s suggestion to me after I’d encountered problems with the 404 build). But then, as I noted last time, while I’ve always like Kirsten’s Viewer, my hardware has tended to sulk badly when using it.

However, for those of you missing Kirsten’s Viewer, here’s yet another update for you! Going on feedback following my original piece on S19’s return (in comments, IMs and DMs), it’s good to know the viewer still has loyal fans!

You can’t keep a good viewer down – Kirsten’s S19

kirstensThe blog post says it all – “old school” – a simple message with a lot of meaning. Kirstenlee Cinquetti has been twiddling under the hood with the S19 (v1-style) version of Kirsten’s Viewer with the result that an updated version – code-named “Blackbird” (version S19.404 at the time of writing) was released via Google Code on Wednesday 24th April.

This is the second time there has been a surprise update to one of Kirstenlee’s viewers – in September 2012 a couple of updates were made to the v2-style S22 viewer. As with those updates, the new release of S19 does not mean that Kirstenlee is returning to the field of viewer development per se. Nor is this a complete update – although it does incorporate a lot of v3 code and is Server-side Baking ready.  As it stands, the release – as with the S22 releases in September 2012 – is offered “as is” and without support – and there is no time scale or firm commitment where further updates are concerned.

As readers, know, I’m not a fan of the v1-style interface, but I admit there is something pleasing about loading and running this release – quiet possibly because it is one of Kirstenlee’s builds, which, despite the odd hiccup between the viewer and my hardware, I’ve always felt pretty much at home with. Perhaps it’s the green :).

Some of the New Bits

I’m not proposing an in-depth review, but here are some of the main features in the update.

Server-side Baking / Appearance: as mentioned above, this update is “server-side baking / appearance ready – it will render avatars correctly on SSB/A-enabled regions and avatars using the viewer will render correctly to others. However, the new “hover” mode partial z-offset “fix” is not included in the Edit Appearance floater.

SSB/A-OK: O the left - S19 Blackbird rendering my Alt (on the SL SSB/A beta viewer) and I correctly on an SSB/A-enabled region; on the right - I render correctly in my Alt's view
SSB/A-OK: O the left – S19 Blackbird rendering my Alt (on the SL SSB/A beta viewer) and I correctly on an SSB/A-enabled region; on the right – I render correctly in my Alt’s view

Mesh Uploads: Nicky Dasmijn’s mesh uploader is included in this release of S19, again bringing it into line with other viewers and the age of mesh.

Anaglyph [3D] rendering: Kirsten’s first introduced 3D rendering in the S22 viewer. While still very experimental, with all the interest in Oculus Rift, its inclusion in S19 with this release is perhaps a little pertinent and timely as a means of generating a 3D view in a viewer.

If you have 3D glasses, Kirsten's latest S19 (404+) gives you a 3D world

Restrained Love: RLV comes to Kirsten’s viewer with a dedicated preferences panel which includes the ability to set a “profile” against your RLV use – one of “BDSM Persona-Player”, “BDSM Role-player” and “Non-BDSM”. These define how many (and which) RLV controls can be blacklisted (i.e. prevented from operating), so that, for an example, someone using the “Non-BDSM” option can make use of options such as automatic chat redirection, shared folders for changing outfits and “forced” teleports which necessarily having to also have the more restrictive RLV options active.

Pathfinding: Kirsten’s Viewer S19 also gains options to display pathfinding information on linksets and characters. These options are on the Tools menu. As S19 supports OpenSim, there is no navmesh visualisation as there is no Havok sub-licence agreement.


Overall, this is a sudden and interesting update to Kirsten’s original v1-style viewer, incorporating a lot of v3 code which more than makes it capable of running on today’s grid. On the whole I found it to be stable, and with performance levels I’ve tended to get from Klee’s builds (somewhat lower than with other builds for reasons I’ve never fully fathomed). I did encounter an odd issue – while I could run the viewer in deferred mode, when I enabled shadows, my in-world view turned black, and refused to come out of its sulk until I disabled shadows once more. Whether this was due to a problem with the viewer, or simply another of the hiccups which seem to occur between my hardware an Klee’s viewer builds at times, I couldn’t say.

There are a few bits missing from the update as well – no Depth of Field for photographers, for example, (although Dawny Daviau, Kirstenlee’s partner, tells me this might be coming). So don’t expect it to be fully up to S22 / v3 standards in terms of options, etc.

Again, this release is not a return of Kirsten’s viewer per se, although there is an open invitation for those who like the viewer or the v1-approach to give it a go. Just remember, support isn’t given – and it may be a while before a further update arrives.

In the meantime, some more 3D, this time courtesy of a video demonstration from Chantal Harvey, filmed back when the capability first appeared in Kirsten’s Viewer.
