Some Duplicated models are casting shadows even though cast shows is disabled for them.

Some Duplicated models are casting shadows even though cast shows is disabled for them. This happens after i build lighting.

Seems it happens with geometry i duplicated that was already in the scene… just duplicating more lights and stuff…Some of the meshes that are set to not cash shadows dont… but as u can see… some do… possibly duplicates… (shadows appear after lighting is built.)
