Diffuse_Level on top of the Diffuse_Raw channel, with the Diffuse_Level multiplying the Diffuse_Raw to get the diffuse_result (there is no need for the diffuse_result layer is there in Ps ? All in linear space, the results are ugghh, when I preview in sRGB, it's still uggghh. I'm actually fighting with this, I can't believe this, unreal. I swear I'm doing something wrong ?
