“The first one of these applications is Unwrella, which is an automatic unwrapping tool. This saved me A LOT of time, and we use it extensively for other projects as well. I used it to unwrap almost everything except for a few specific models I had trouble with at the time (the current version uses UV seams, but the beta version didn’t).
If I wanted different parts of a model to be given more/less texture space, I’d capture a morph target of the model in its normal state, deform it so that its parts’ sizes in relation to each other matched the relation I wanted to have UV space, unwrap it with Unwrella, and collapse the stack and apply the morph target to bring the XYZ space object back to its original form.”
