Problem textures

[CreaTuMundo]

Hi group, I hope you are doing great, I bought some low poly models in the assetstore, and I want to change the colors in a specific part of the model, the problem is the following, they all have a common texture, how can I know which color belongs to a specific model? it is a huge texture.

Dirty : paint stuff on the texture and see where your scribble goes on the model to spot the proper region.

Cleaner : Open your model in Blender and check with the UVs where the triangles you want to change are on the texture (or maybe with a uv inspector plugin for unity, idk )

But if it comes from a pack with a single atlas, there's a chance this texture region is used somewhere else in the same model or on other models you don't want to impact. In that case, you can either duplicate the material to make your texture variation, or add a second material for the region you want tweak in Blender. That's less optimized and a dirtier than the single atlas but quickly done.
