Non-RGB FBOs are specifically left out of the FBO extension. I would be surprised if you aren't getting glError() set - are you checking it?

Hi list, I've been trying to write the output of a fragment shader to LUMINANCE texture, but all I get then is a completely black texture.

Question: do FBOs support writing directly to a texture with fewer than 4 components - how? If not, is there any workaround?
Thanks
Mark
