I’m using a universal UV unwrapping tool and I need to know the answers to use this tool properly: https://github.com/vilemduha/blender-addons-vilem-duha/blob/master/addons/uv_auto_seam_unwrap.py
- What is an island?
- What is a seam?
- What does “weight” mean in general?
- Why would angle weight be important?
- When is it a good idea to deform the island and when is it a bad idea?
I appreciate the help.

I can answer the first two:
-
An island is a set of faces whose vertices share UV coordinates (in other words, they’re connected).
-
A seam is an edge property that can tell an unwrapping function that the texture doesn’t have to flow smoothly around it.
I think this page explains them well, although it’s for Blender:
Scroll down to where it says “ProTip”.
Adding seams allows a texture to be mapped with less distortion.
