Opengl Post Process

I have write a post process in irrlicht opengl. There is a big limit!
With glCopyTexSubImage call we can save image only power of 2. I have test to render a immage 1024 x1024 and i swap in zbuffer on a geForce 6600GT!
The function will be replace with "Render Directly to Texture" (WGL_ARB_extensions) for render big immage !

Hmm

Not really sure what this means, maybe some information on your project would have helped. However, OpenGL spec does not limit glCopyTexSubImage2D to power of 2 dimensions.
So if you need some more help you should give some more information (well, do that anyway

) I'm very interested in the architecture how you integrated that with Irrlicht.
