Shadow errors

[gfa2]

I'm getting these weird shadow areas. There is no geometry below or touching these area's. This is for an animation and the shadows stay where they are on the geometry as the camera moves. The only thing moving in the scene is the camera.

this looks like the problem that i was having. Is this revit geometry? What does your lighting pass look like?

There is some Revit geometry in there. AutoCAD geometry too. I'm using Brute Force primary and Light Cache secondary.

Would you mind sending the scene or a part of it to support@chaosgroup.com?
