For some reason I cannot get GL_CLAMP (or GL_CLAMP_TO_EDGE, GL_CLAMP_TO_BORDER, i’ve used others…) to work properly. I always see a black line at the top of the texture.
I’ve tried it on a GF3, a GF2, and even on a Riva TNT2 (which incidentally had the least amount of CLAMPing problems). I’ve specified clamping before each and every call of glTexImage and Build2DMipmap.
I’m suspecting this is a Nvidia driver problem, has anyone had this persisting problem? can u share how you fixed it?
