I made a low poly M1895 bolt action rifle for my new game. I imported it into a game scene and it was fine at first, but after a while the rifle turned brown i.e. the material that was supposed to represent the metal part of the rifle (grey) took the image which I used as an image texture for the wooden part. I gave it its old metal texture back, but once I deselected the rifle, the wooden part took the metal texture. It’s like the both materials are trying to have the same image texture.
How can I fix this?
Thanks.
