Hello! I have implemented perspective shadow mapping by rendering to a depth-texture via FBO. After updating to the latest ATI driver (8.1) from my previous one (7.9 I think), the depth image appears to be flipped upside down. If I invert the y-texture coordinate, or downgrade the driver, I get correct results again. Can anybody confirm this issue? From what I know, it appears to me that the y-orientation of the rendered FBO image has changed after the driver update. If this is the case, it would be neccessary to test the orientation at program startup, but before implementing this I would like to know if this really is the problem. BTW, I use OpenSceneGraph for rendering and FBO handling, if this provides any clue. regards chris
