Cool VL Viewer forum

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

This is a bugfix release and a recommended update.

Cool VL Viewer v1.32.2.52 (stable branch):

New in this release:

• Backported from LL's viewer-gltf_mesh_import all recent changes and fixes to the glTF mesh model loader (up to and including yesterday's "fix for transparent meshes").
• Fixed textures not showing in the model preview floater and not uploading when asked.
• Made it so that the camera position in the model upload floater preview takes the model upload scale into account (so that you can still get the model previewed at a manageable size).
• Tweaked the PBR SSR render settings to fix or attenuate some render glitches (SSR still disabled in official builds for now: see the change log for v1.32.2.51 above).
• Code cleanup and some speed optimizations.

Enjoy !

Cool VL Viewer v1.32.2.53 (stable branch):

New in this release:

• Backported from LL's viewer-gltf_mesh_import all recent changes and fixes to the glTF mesh model loader.
• Backported from LL's viewer-release-2025.06 a fix for "crash at meshopt_generateVertexRemapMulti()" that could potentially be seen in low free memory conditions.
• Plugged two potential crash bug cases due to race conditions while periodically cleaning up the mesh repository skin map from unused data.
• Added threaded initial joint rigging data caching on mesh skin fetch.
• Code cleanup (with removal of dead code) and some speed optimizations.
• Windows only: updated the bundled runtime libraries to match the new MSVC compiler version (1944) in use for building the viewer.

Enjoy !

This is an emergency bugfix release and users of v1.32.2.53 should update to it.

Cool VL Viewer v1.32.2.54 (stable branch):

New in this release:

• Reverted/disabled the "threaded initial joint rigging data caching on mesh skin fetch" optimization introduced in v1.32.2.53 and which was causing crashes on some systems under certain (unclear) circumstances. See this message for details.
• Plugged the information leakage (IP, user agent string, etc) to unauthorized sites used for Media on a Prim (MoaP), due to the implicit MIME probes connection. There is a new "Filter MIME probes" check box in the "Preferences" floater, "Audio & media" tab, "Media" sub-tab to toggle this new feature (defaulting to enabled). Do read the tool tip for it !

Enjoy !

Cool VL Viewer v1.32.2.55 (stable branch):

New in this release:

• Backported from LL's viewer-gltf_mesh_import all the latest changes and fixes to the glTF mesh model loader.
• Backported from LL's viewer-release-2025.06 a fix for "pressing cancel on material picker reverts an override even when it shouldn't".
• Fixed a crash bug in the asset storage code, sometimes seen when closing the viewer during the login process.
• Fixed a crash on exit that could happen at the very end of the program shutdown process (while running the C++-compiler-generated cleanup code), when the LLPipeline global instance member variables are destroyed (the bug was in the LLRenderTarget destructor that could try and use GL calls after the GL context is destroyed).
• As a corollary of the above bugfix, made LLGLManager into a purely static class (instead of using a global instance, also subject to the unpredictable destruction order), so that the GL context validity flag (and any other flag) in it can be safely tested in the destructors of global class instances.
• Re-added (fixed) threaded initial joint rigging data caching on mesh skin fetch (and, just in case, this feature can be disabled via the new "CacheMeshJointRiggingOnFetch" debug setting). See this message for details.
• Fixed an issue with PBR reflections shaders being wrongly fed with the mirror clip plane for a mirror which is no more active (not updated any more since not in FOV or too far away, or after mirrors rendering got manually turned off).
• Updated libsqlite3 to v3.50.3.

This is an emergency bugfix release and users of v1.32.2.55 should update to it.

Cool VL Viewer v1.32.2.56 (stable branch):

New in this release:

• Properly fixed the "threaded initial joint rigging data caching on mesh skin fetch" code, this time. See this message for details.
• Code reshuffling and cleanup.

Enjoy !

This is a maintenance release and a recommended update.

Cool VL Viewer v1.32.2.57 (stable branch):

New in this release:

• Fixed a crash bug in the GetEnvironmentStatus() Lua function due to a typo in a cached debug setting name (introduced in v1.32.2.49).
• Backported from LL's viewer-2025.05 a fix for a crash sometimes seen when uploading some bogus Collada models.
• Backported from LL's viewer-gltf_mesh_import "warn or log when texture gets scaled down for material and model upload".
• Fixed the disabled media not playing on user manual "play" request (e.g. from the viewer media HUD): asking to play a media now automatically re-enables it if needed.
• Added support for the new "avatar welcome pack" selector ("Choose new stock avatar..." entry in the "Edit" menu), and implemented a workaround for the bogus format it uses for its SLURLs (that would otherwise be interpreted as grid/region location SLURLs by the viewer).
• Updated libhunspell to v1.7.2 and changed the spelling code to use its modernized C++ API.
• Minor code cleanup.

Enjoy !
