well what i wanna do is, there is a house in a game i wanna mod that uses a brick texture shared by a few other houses, what i wanna do is change the UV map of the house to be able to use a method called texture baking, witch renders the ambient occlusion onto the texture, but if i do that, the rest of the houses in the game that share the same texture will look wrong, so what i wanna do is make a new texture for that specific house, put it in the asset pack and make the house model use that texture instead of the shared one.
Long story short, i got 2 houses sharing one texture image file, what i wanna do is make one of the houses use another image, not shared with the other house.
both the models and the textures are located in sharedassets2.assets
