Errors displaying translucent object (shadows, overlapping geometry)

Hello! I’ve got two questions today :slight_smile: (for now) Here is a picture to help describe my problems:

Question 1: (picture on left) is there a way to tint the shadows casted by a translucent material/mesh ? In the example they should take a greenish tint. Something like this is described in the UDK [documentation][2]

Question 2: (picture on right) is there a way to mask overlapping geometry for translucent materials ?

Thank you for your time ! :slight_smile:
