UV scaling

Mr.Moose

So far I usually leave all my UVS very consistent, but I've seen some videos scale up certain parts. Its understandable that you need more detail in certain places, BUT doesn't it make it harder to line up skin details and such? IE if you unwrap the arms separate the torso and scale the torso or something, and apply the same size skin texture it WILL be larger or smaller on one or the other..
So..
Is it common practice to scale or such, or just scale and morph uvs to keep consistency ?

It's something that you just have to be smart about. It's common to have some variation in scaling, but if it's going to cause you more work, it might not be a great idea.

You could hide the seams - maybe there's a collar and the blending between head and torso isn't visible, or backpack straps on shoulders where arms meet the torso.
