Share UV maps between objects

I saw this: How to share one UV texture map for multiple meshes? - Questions & Answers - Unity Discussions

But I need a concrete answer. Can I share UV between say different swords, or armor pieces, or potions, etc.

As long different objects didnt unwrap themselves at the same location I can see no reason why you cant share the texture file.

So when you do your unwrap, make sure each object is located on a different place on the bitmap. You should then be able to share a texture for multiple objects.

The UV map itself though belongs to each object alongside the mesh.
