Hello how are you doing.
I UV mapped a vehicle's door (front passenger side), but after it, a strange black stripe appears although the texture is white and I selected all the polygons to map:
BEFORE:
AFTER:
GTA:
UV Mapper:
As you can see its visible ingame and the texture is completely white (except for the hwaypatrol letters but it has nothing to do with it.)
It's really annoying, any ideas?
