Hi,I've merged my changes with the current SVN and experienced some strange things too. Wojciech I think has added negative polygonoffset when culling back faces. This leads to selfshadowing everywhere on my ATI card. When supplying positive values however it works on ATI and NVIDIA (when choosing a bigger value though)
I've attached the merge as is, since my changes involve a function to set the polyoffset from outside (see attached description for further details). I also agree to Robert, that we need definitely more unit tests for this, but I have that strange feeling, that won't be enough, since I had very different experiences with different card/driver combinations. (e.g. ATI .. they have inverted the t-coordinate of the FBO-Texture in their newest drivers ...)
I hope my changes are of any value. cheers psy
