Currently one light model, more to come. All combined in some render pass. I use 5 GBuffers. 1 RGBA for color, 1 RGBA for normals and specular, 1 R (32 bit red) for depth, 1 RGBA for the lightning colors and 1 for the final pass (this is mainly used for post effect).

I still need to make a small tech demo that shows off some nice features.
