This is the technical term for the process of mapping a flat texture on your three-dimensional object. The most hands-on example for this is Christmas chocolate:
Regardless of that, you can not eat it.
Where can I see them?
To look at an object's UV mapping, you'll have to fire up Blender (or a 3d editing software of your choice).
An object's UV maps are visible in the Data tab:
How do I edit the UV mapping?
To look at an object's UV mapping, you'll have to fire up Blender (or a 3d editing software of your choice).
Open the UV editing perspective, select a mesh, and switch to Edit Mode. If you select vertices in the viewport on the right, you can see their UV islands in the UV editor on the left:
To transfer UV maps between two objects, they need to be topologically identical (they must have the same number of vertices, faces and edges). The shape can change.
You can find the UV transfer menu under Object -> Data Transfer.
You can pin the edges of the UV map and then unwrap everything inside by angles. This is one of the easiest ways to adapt one UV map to another (DICrash)
