Hi Thomas, Thank you for the email. Yes, it does seem to be the problem of OpenGL. Here is the engine: Detected OpenGL version 4.5. Shaders available. Detected GLSL version 4.50. OpenGL graphics engine: GL_VENDOR: Intel GL_RENDERER: Intel(R) UHD Graphics 630 GL_VERSION: 4.5.0 - Build 24.20.100.6227
Fixed by setting precomputed_lighting. I found setting use_shaders, 0 seems also a workaround, not sure if it is the right way though.
