view3dscene gLTF error on NVIDIA about view3dscene HOT 4 CLOSED

That's most likely a problem with our shader code, specific to NVidia GPU. Implementation of physically-based rendering (from glTF materials) indeed uses materialInfo name a few times.

Please run view3dscene with the additional command-line option --debug-log-shaders and attach the log to this issue. This log will be longer, it will contain the shader code actually used (it's constructed by a shader composition logic in Castle Game Engine), and eventual warnings from GPU, so I'll be able to quickly find the error :)

Okay here the log, thanks

Thank you! It should be fixed in latest CGE commit.

While I don't have access to NVidia GPU right now at home, I was also able to reproduce the error with NVidia cgc compiler, and confirmed that the fix helps.

Please test and reopen this if the problem persists on your GPU.

( To test

• You can use view3dscene from http://michalis.ii.uni.wroc.pl/view3dscene-snapshots/ in ~15 minutes
• Or you can use view3dscene from latest CGE snapshot on https://castle-engine.io/ in ~4 hours
• Or you can get sources and compile now: latest https://github.com/castle-engine/castle-engine/ with latest https://github.com/castle-engine/view3dscene .)

Fixed, thank you
