Hi Joseba,

I use FBOs but the problem is that in the beginning of my application it 
says "RenderStage::runCameraSetUp(), FBO setup failed, FBO status= 
0x8cd6". Could this be the problem? And what is the reason for that?

Could you tell me which internal format you where using and which issues 
you were talking about?
