Robert I'd agree that I'm dealing with a driver bug. I'm just not sure what the bug is. I think we are working in a underspecified area of OpenGL when dealing with mipmap levels smaller than the compression block size. However, I know that my driver generates 2x2 and 1x1 mipmaps for hardware generated compressed textures and this would suggest that it should happily work with these levels.
I don't agree that it is unrelated to the OSX driver issue. Certainly the drivers are different and the symptoms may be different. But they both appear to touch the same question; what happens with mipmaps smaller than the block size. I don't have access to an OSX machine however, so I cannot investigate this claim further. I have not tried different driver/hardware/OS combinations. I'd agree that this would be useful, but I'm somewhat limited in how far I can go with this. I'd agree that a change to the core OSG is not warranted at this time. The models that cause the problem are not distributable. I may continue to try and create a model that has the issue as time permits. Scott
