Are normal maps Y+ or Y- ?
Just wondering if anyone can give a straight answer as to whether normals in UE4 are Y+ or Y-? As far as I've found in my searches, everyone says that the Y channel should be highlighted on the bottom but I don't know if that means Y+ or not.

It is Y-. Having only two options here, you can basically eyeball it :)
