Hi
How can i render to a float-texture? I cannot render to the framebuffer and use glCopyTexImage because the framebuffer is RGBA8.
Would i need to use a pBuffer???
I mean a float-texture as specified in ATI_texture_float.
Thanks,
Jan.

yep, you need to create a fp-pbuffer and render to that, then use render_to_texture extension to bind that pbuffer as a texture.
