I use sky light for my mobile game as the only light source. Cast shadows is disabled. On mobile devices sometimes, not often though, some buildings are pitch black. What is the reason?
Unfortunately no. Just some buidlings are entirely black except lights. I don’t use shadows
Double check that you’re not using DFAO, it’s one of the few things that can block skylight lighting, but I wouldn’t expect it to be enabled by default on mobile.
The buildings look exactly the same as when there is no sphere. Sphere is added at the beginning of the game.
The thing those buildings have in common is that they are merged. Not merged meshes don’t have this problem.
