Scaffolding: Shadows are incorrect

Request from Discord: "i feel like if there is a shadow from the top layer on the bottom layer, there shouldn't be a gap where sun passes through in between the shadows. so either green be shadowed or purple be sunny. i haven't checked all of the items just noticed this in scaffoldings"

"Well physically, one object that is whole cannot cast shadow on 2 things and the total shadow not be connected. Like it isnt physically possible in real life"
