Re: [osg-users] INVALID_OPERATION with compressed textures with mipmaps in OSG 3.4.0.

Hi Scott, The problem under OSX looks to be a driver bug, there is small chance that it's related to the problems you are seeing but likely a different issue. The problem you describe sounds like a driver bug too, testing out without other drivers/hardware/OS combinations would help with this.

NOTE: the current development version of ANGLE is targeting OpenGL ES 3.0, if you want to be more up to date. I am not sure about its level of completion and stability though. Maybe you can find more complete (commercial?) virtualization solutions to run the DX backend. Also maybe Wine is

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

Sorry. It keeps trying to encrypt the message. Robert While continuing to build a model that results in the problem, I discovered something I didn't see before. The IVE model had an incorrect number of mipmap levels (it had 8) for a 32x32 texture. It makes sense that glTexStorage2D would
