Question by pragmascript · Aug 11, 2011 at 05:52 AM · shaderlightingrendertexture

albedo in post effect shader

Hey,

I need the albedo of the scene in a post effect shader, but it seems you would only have access to the albedo inside a lighting shader. Can i render the albedo to a rendertexture somehow?

Wouldn't the "albedo" of the rendered frame just be the RGB?

No, since it will be lit.

it would be the rgb if there was no lighting and ambient-light was set to white i guess

True - if you don't $$anonymous$$d running an extra pass, that would certainly do it.

@pragmascript So - this would require a second pass, but you could render the entire scene with Replacement Shaders, using an Unlit shader to give you no lights, specular, etc. That should give you a scene with just your albedo.
