Bug: Shadows show up between light and caster

Unity Engine
1

I encountered a lighting bug. If the range of a light just begins to touch a shadow-casting object, the shadow shows up on objects between the light and that object. It’s when the sphere of the light range just touches the first face, before it encompasses the whole thing.

In this picture, the big box on the left does not cast shadows, and the one on the right does cast shadows. This happens in Unity 3 as well as 4.

Has anyone else encountered this before? Any solutions?

Seems like you got a repro case right there… please submit a bug report and attach the project so we can have a look at that.

Thanks

Thanks, I submitted a report. I’m also attaching a simple project folder here just in case anyone else is curious.
