Hello, I have a question regarding Live Unwrap.
It seems that after I marked seam, the UV map got smaller? I had to manually click UV > Pack Islands to get them to occupy the whole texture image. On the other hand, unwrapping it without Live Unwrap produced the expected result. Is there something that I missed here?
Your UV island can be whatever size you want, only impact will be the texture density will differ from one another once they are mapped to something. But you have full control of what you want to have more pixel density than any other thing. Your model should have the scale applied so the UV is relative to your model, but yeah, when you unwrap the island can be one size and then when you pack the islands, it will try to occupy the most amount of texture space in the 1 to 1 grid and it will make the islands as bigger, but that is ok, nothing to worry about.
