How do I have transparent mesh and retain shadows?

I will have to test this out once I get home today. Last night I did some more work with it and was having some crazy issues. I got an infinite loop error whenever I tried walking on the roof and once I managed to fix that the entire object became a trigger. Walking on the roof causes roof to become transparent even though the “InteriorVolume” is at floor level and .5m tall. I even removed the “InteriorVolume” at one point and the event was still triggered. Called it a night after that.

Will give an update after I try some more things :slight_smile:
