I’m trying to create a realistic material for leaves using the “Two Sided Foliage” shading model.
Out of the box this Shading model works fairly well. By default if I place my camera behind my leaf and loo towards the sun I am getting cast shadows from the objects on the topside of the leaf and the diffuse values from the top face. However the property I would like to control is the value of the colour on the side opposite to the light. That is to say I would like to make the amount of light diffused through the leaf less than the 100% that the Two Sided Shading model propagates to the opposing side of the face.
I understand how to make layered materials using Material functions and the Make Material Attributes node but this doesn’t allow me to isolate the contribution of the Two Sided Foliage shading model as the shading model is in the material Details tab.
Is it possible to combine shading models in UE4.7?
Thank you to anyone who can help.
