3D textures with internal format GL_LUMINANCE16_ALPHA16 don't work?
I am developing an OpenGL application that needs to use 3D textures with internal format set to GL_LUMINANCE16_ALPHA16 and format set to GL_LUMINANCE_ALPHA. I got it working for NVidia cards, but I do not get it to work for ATI cards. My code works OK if I use the standard RGBA texture format.
The format works correct for 2D textures.
Is this a know problem, or am I do something wrong?
