RTT + draw2DImage, not working under OpenGL!

Post by LovehinaX »

I’m having some trouble with draw2DImage() function in OpenGL... What I’m trying to do is render a scene into a RTT texture and then display that texture on the screen with draw2DImage(), pretty standard.
Now, this works perfectly in Direct3D and even in software drivers, but in OpenGL it just displays a blank rectangle... Could this be a bug or something, since I don’t have any problems using draw2DImage() in OpenGL with a regular texture...

Thanks in advance, Lovehina...:)

No, RTT works under OpenGL. Maybe your gfx driver does not support frame buffer objects? Are there any warnings on the command line?
