How to stretch rectangular UV islands over entire texture space?
I'm trying to UV unwrap this hair. The hair is made of many separate strands so many separate UV islands. The image shows the UV island on the right stretched to fit the texture space. It's an example of what I want. I want to center and stretch all individual islands to fit the entire texture space, all at once, automatically. Is there a way to do this? I'm assuming if this is possible it may take multiple steps, that's okay, I just need a way to do this without centering and stretching each individual island manually because that will take me closer to the edge of madness.
Alternatively, if that's not possible, it might help if I could do some operation to make all the islands fit the texture space on the y dimension. So essentially an operation to make each island as large as possible, automatically. And a way to center them automatically. That could get me partway there.
