Just a question about the renderer

In the Realistic Rendering scene, there is something ‘missing’ in a visual point of view in my opinion, the fact that the shadow color is not affected by the light which is (in theroy) passing through the cloth, is it something to set in material properties or is it for the moment a limitation of Unreal Engine 4’s lighting system ?

It is a limitation for now with SSS i believe. You can ask more about it to the rendering team at the Twitch stream next week!
