I’m editing a helmet from Skyrim in Blender to remove a unneccessary feature, and my question is this.

Can a Uv map created for the mesh in Blender mimic the shape, position and pattern of the objects already existing texture?

I’m having trouble understanding your question, an image/mockup of what you want could help.
