Hello!

I'm new to forum and to openGL as well and struggled these last few days to get an SSAO shader to work.

For this I needed a Color, Luminance, and Depth Texture. Is it possible to acquire all of these with a single pass?

Thanks!

Well, if I am not mistaken (and I might be) you can use a texture array http://www.opengl.org/wiki/Array_Texture to pass a arbitary number of textures to a single pass I guess.

The question is about generating the textures as input for another pass. Array textures will not really help directly. glDrawBuffers should be what the OP is looking for though.
