Is there a way to find out if the renderer has decided to draw a given face?
For example, I want to know if my sun object is behind a tree object. The render has already calculated whether the faces in the sun are visible to the camera. I would like to be able to loop through the faces in the sun object and test if each one can be seen by the camera. This is different from the visible property, which remains true even if the object is behind another object and not rendered. Thank in advance for any suggestions! Ralph
