Hi,
I declared a mat3 variable as uniform, and I am trying to specify its value from the app. But whatever I try is failing. I tried to get a GLSL “pointer” (via glGetUniformLocationARB) for each of its component, i.e. glGetUniformLocationARB(program, “MyMat3[0][0]”), or for each of its rows “glGetUniformLocationARB(program, “MyMat3[0]”)”, or even directly for the whole matrix, but everything is failing. I can successfully access variables such as vec3, structure, and everything, but mat3 not to avail. Are there specific issues with matrix variables?

PS: Win32, nVidia 6600 (77.72 driver)
PPS: Are newer nVidia drivers (81.xx) better/worse than older (77.xx) for OpenGL 2.0 support? Any new problems?
