View Full Version : Shadow pass, extra shadow artifacts

01-02-2006, 10:53 AM
I am having difficulty getting a good shadow pass render for compositing. Here is my problem....

My scene is setup with several objects that are casting shadows and Unseen By Camera. They are casting shadows just fine. I had a ground plane and some other random geometry that is Recieving Shadows. All is working fine here too, and I end up with a black image with an alpha just for the shadows I want.

HOWEVER! Im getting extra shadowing on the sides of the objects Recieving Shadows. Its as if they are recieving a shadow from themselves, even though Self Shadow is turned OFF. As far as I can tell, the only place they can recieve shadows is the shadow casting objects.

Where are these extra shadows coming from?! Its shadows in the proper areas where shadows would naturaly fall on the objects, but with self shadow off, I cant explain it and can't seem to find any combination of settings that will eliminate this extra shadowing on the Recieve Shadows objects.

Any help is greatly appreciated. Thanx guys!
