I'm getting a strange hard edge in my comp where there should be a soft shadow. Basically my object has motion blur and cast shadows on. There is a shadow "only" layer catching the shadow. When the moblur and shadow are present together I am getting a hard edge to the shadow where there should not be one.
There are no edges present in any other layers that could be causing this and I've upped the raytrace quality to 15 with no success. The issue also doesn't appear until I do a final Best Quality render. Basically I am totally stumped. Any ideas?
