Here is a new release of the Cool VL Viewer, available now from http://sldev.free.fr/:

This is a minor maintenance release but nonetheless a recommended update.

Cool VL Viewer v1.32.2.31 (stable branch):

New in this release:

• Fixed a bug introduced in v1.32.2.26 and which was causing a failure to compile the PBR terrain shader with some pre-4.6 OpenGL drivers. See this thread for details.
• Backported from LL's viewer-develop a change to allow again HDR tone mapping when "RenderSkyAutoAdjustLegacy" is TRUE. As a result, made this variable default to FALSE again (toggle is "World" ->"Environment -> "Adjust legacy to PBR").
• Backported from LL's viewer-develop "skip ambient probe sampling when we are in classic mode. Ensure that our passed in ambient lighting is the only thing that gets applied".
• Windows only: backported from LL's viewer-develop a fix for failures to initialize the full screen mode seen under Windows 11 with some drivers.
• Added missing syntax highlighting and tool tips support for the llLinear2sRGB() and llsRGB2Linear() LSL functions in the script editor.
• Updated xxHash to v0.8.3.

Enjoy and happy new year !

Cool VL Viewer v1.32.2.32 (stable branch):

New in this release:

• Backported from LL's viewer-develop a fix to "crash when ParcelProperties' Bitmap is of wrong size".
• Backported from LL's viewer-develop a fix to a potential "crash at LLDrawable::isState()".
• Backported from LL's viewer-develop support for the new server-side "CantTransferMoneyAgentIsBlocked" message.
• Improved the strictness of the textures max fetch/render size limitation algorithm (now applies to all fetched textures instead of just to LOD textures).
• Implemented debug message logging for the new event poll messages metadata (seen in viewer log when the "EventPoll" debug tag is enabled).
• Updated FMOD Studio to v2.03.05.
• Minor code cleanup.

Enjoy !

This is a minor maintenance release but all users should nonetheless update to it.

Cool VL Viewer v1.32.2.33 v1.32.2.34 (stable branch):

New in this release:

• Backported from LL's viewer-ForeverFPS changes to how PBR waters render, now closer, if still far from equal, to Windlight waters: the Fresnel refractions and reflections are now back to what they used to be, making the water look less "oily".
• EDIT (v1.32.2.34): fixed the inout vs in parameter type mismatch with the new water shaders, that could cause shader compilation failures (and thus crashes) in PBR mode, with some OpenGL drivers. See this thread for details.
• Reduced the wait for staled/stuck threads in LLThread::shutdown() from 60s to 250ms.
• While shutting down the viewer, do not sleep inside LLAppViewer::frame() any more, even with frame-limiting on, or while still at the login screen.
• Windows only: when using OpenGL shared context threads, do not any more attempt to destroy the said contexts on viewer shutdown (this caused minutes-long wait or even dead-locks under Win11 24H2); instead, just (temporarily) "leak" them and let the (brain-dead) OS clean up after viewer exit...

Enjoy !

Cool VL Viewer v1.32.2.35 (stable branch):

New in this release:

• Backported from LL's viewer-ForeverFPS "fix media failing to function on PBR materials".
• Backported from LL's viewer-ForeverFPS "add some haze to the distance on PBR water".
• Backported from LL's viewer-ForeverFPS "add support for PBR water exclusion surfaces" (i.e. this restores invisiprims support in PBR rendering mode for hiding water).
• Backported from LL's viewer-ForeverFPS "make LLFolderBridge::checkFolderForContentsOfType() cheaper".
• Changed how the avatar profile data is updated, which might solve this UI glitch.
• Changed the central Cookies database and CEF cache locations (Cookies are now kept in a cef_cookies sub-directory of the per-account settings directory, and the cef_cache sub-directory was moved into the viewer cache directory, were it belongs). This should be transparent to the user (old Cookies central storage is automatically copied to the new location).
• Windows only: backported from LL's viewer-ForeverFPS a fix to "switching screens can break text rendering".
• Updated FMOD Studio to v2.03.06.
• Minor code cleanup and optimizations.

Enjoy !

This is a minor maintenance release but still a recommended update.

Cool VL Viewer v1.32.2.36 (stable branch):

New in this release:

• Fixed the bug in font vertex buffer rendering of UI input lines, which caused the partnership line to stay blank in the Avatar profile floater. See this message for details.
• Backported from LL's viewer-ForeverFPS "fix for font vertex buffers not accounting for dynamic cache values."
• Backported from LL's viewer-ForeverFPS "additional PBR water fixes and tweaks".
• Backported from LL's viewer-3423 "add Lua as compile target". As a result, the "Mono" check box in the LSL script editor has been replaced with a combo box listing the three possible compile targets (i.e. the three possible compilers used by SL servers to compile your LSL scripts): "LSL2", "Mono" and "Lua". The "Recompile scripts in selection" sub-menu (in the "Tools" menu) also got "Lua" added as a target. Please note that the Lua compile target is not yet available on the main SL grid and is still experimental.
• Minor code cleanup.

Enjoy !

This is a bugfix release and everyone should update to it.

Cool VL Viewer v1.32.2.37 (stable branch):

New in this release:

• Fixed bugs that could cause some ALM shaders to fail to compile with some GPU/driver combinations. See this message for details.
• Backported from LL's viewer-ForeverFPS "switch from GL_RGB16F to GL_R11F_G11F_B10F for reflection probes to help reduce memory bandwidth and VRAM pressure". Extended this to "hero probes" (mirrors) as well.
• Backported from LL's viewer-ForeverFPS a fix for "waves not applying without Transparent water" in PBR rendering mode.
• As a result of the above fix, reintroduced the simplified (faster, more accurate/correct) water edge shader for PBR.
• Backported from LL's viewer-load-avatars-faster "drain UDP socket to avoid dropped packets".
• Do not throttle any more asset UDP downloads ("XferThrottle" debug setting set to 0, and made it so that this value now disables the throttling).

Enjoy !

Cool VL Viewer v1.32.2.38 (stable branch):

New in this release:

• Backported from LL's viewer-ForeverFPS "fix constant glTF asset re-requests".
• Backported from LL's viewer-ForeverFPS a fix to "accidental double linearization" in the PBR water shader.
• Backported from LL's viewer-ForeverFPS "remake glyph count into cache generation" for font vertex buffers.
• Backported from LL's viewer-reslease-2025.03 "theoretical earlier start to asset downloads during startup".
• Backported from LL's viewer-project/lua_editor "use correct 'lsl-luau' compile target".
• Now properly only enable Lua compile target operations based on simulator features.
• Added tool tips and syntax highlighting support in the script editor for the new MASK_COMBINED, OBJECT_PERMS and OBJECT_PERMS_COMBINED LSL constants.
• Implemented proper dropped UDP packets accounting for the new LLPacketRing code.
• Integrated Leviathan's contribution for the AgentUpdate UDP message sending algorithm, and added a configurable "MaxAgentUpdateRate" debug setting to allow fine-tuning it in real time. See this message for details.
• Fixed the PBR (non edge-)waters appearing too bright in render probes (reflections and mirrors): now use the edge-water shader (opaque water shader) for these (which is also faster).
• Added an "Edit my AI characters..." entry to the "World" menu to allow opening a web browser on the corresponding page/site. Please note that, sadly, the OpenID auto-login feature does not work for this site and the site keeps forgetting your login credentials, even when you check the corresponding box to save them (the latter also happens in system browsers, so this is a website-side bug).
• Code cleanup and minor optimizations.

Enjoy !

Cool VL Viewer v1.32.2.40 (stable branch):

New in this release:

• Backported from LL's viewer-release-2025.03 "make probe count adjustable to better accommodate low VRAM scenarios" for the PBR renderer. Added an "Advanced" -> "Rendering" -> "Deferred rendering" -> "Number of reflection probes" sub-menu to allow changing this number.
• Backported from LL's viewer-release-2025.03 a "fix for friends online status race condition on login".
• Backported and adapted from LL's viewer-project/lua_editor various changes to the script editor to support the upcoming LSL/Lua compiler as well as in-world objects native Lua scripting (now officially named "SLua"). Note that, for now, these changes are only available in some regions on Aditi (e.g. SLua* regions).
• Fixed a bug which caused the PBR terrains render material in the newly entered region to get destroyed when crossing a sim border from a neighbour region.
• Minor code cleanup and optimizations.
