I have a problem with 3D texture, I think with its size. I'm creating a cube of 512x512x96x1 voxels and it is displayed correctly with shaders. But when I'm increasing size of this cube it doesn't display at all (black cube). As I calculated it looks like I can only upload about 24MB of 3d texture to the video memory (!?).
I'm working on Win 7 with NVidia FX 1600M. I have to say that some time ago I worked with 512x512x125x2 cube with no problems (but without shaders!).
Thanks for any help!
