VRay Diffuse render element = Corona diffuse CShading_SourceColor?

Hi, is that comparision right?
I’m not shure because of the corona output looks too dark respect to original textures and playing with gamma intensity breaks jpg tests.

Hi, I am not really sure what information you need exactly. Could you provide and example of Vray vs Corona diffuse element, so that we could compare them?
What do you need this element for?
