I have to do one of those 3D floor plans. How do I render without seeing the ceiling, but the ceiling needs to block the sun.

[image] Converting Arnold area light to Vray area light I have to do one of those 3D floor plans. How do I render without seeing the ceiling, but the ceiling needs to block the sun. I’m super curios about this too. I seen this done on the evermotion scenes. but the few I purchased there was no…

I usually use the slice modifier. I make a copy of the walls with the ceiling attached. I apply a slice to both remove top of one remove bottom of the other. Then the one I removed the bottom on (top of walls) and in obj properties turn that non-vizable to camera. That way it still casts shadows and…
