Test failed :( The WARP microcode seems to be somewhat picky about texture size because even non-mipmapped texture with GL_CLAMP comes out with wrong coordinates. And GL_REPEAT produces total crap. So I didn't even bother to check if npot mipmapping actually works... -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- This SF.
