I've baked my normal map with no problem from xNormal to Painter with settings in xnormal as flipped Y (-Y). I'm not sure if this has caused the opacity map to change course because... (here's a picture for more understanding)
and so basically, the glass on the right cupboard door is what i'm going for particularly but the left one isn't doing the same, instead it's inverted?. They're both separate meshes under the same map and mask and I've checked in maya if the normal faces are in the right directions and they both are.
Any ideas on what's happening?
