I notice that RB didnt metion about GBuffer and deferred Lighting? Is this for advance only? I havent gone through the whole shader tutorial yet but Ive done the Lighting shader. and GBuffer is not mention in there so i figured that Deferred lighting will never be mentioned as the next part is for texture. Is the tutorial here another way of doing some lightings in XNA? I've also check some unity tutorials about shader and some mention this GBuffer. So im quite confuse.
