Hi,
This is my first Blender scene. I’ve successfully tracked footage from an eight story parking lot and used the camera setup.
I wanted to drop particle driven balls on the building roofs, but found I couldn’t get the roofs to be shadow objects with collision working. Do I have to duplicate the roofs to a different layer, make them collision, and hide them from the camera, or are there other methods?
Can’t attach or I would include a pic.
thanks for your response.
