Okay, so I have been working on a mesh for the past few days, and I finally got it how I want it, but...
Part of the mesh is messed up. Near the bottom of the ears, it is darker than it should be, making it partially transparent ingame and bodyshop.
I'm not sure what I did wrong.



And when you look at it from above, the left ear is completely black.




So, where did I mess up?
I attached the OBJ file.
