Re: [osg-users] Buffer problem

Hi, OpenGL (for identity projection) has 0,0 at bottom left. Your cam prob has 0,0 at top left (first pos in the buffer). Easiest is to just swap to top/bottom texture coordinates when you apply the texture. jp On 26/04/10 08:32, Anthony Face wrote: Hi, I have a texture problem. I use memc
