I am making a stuffed animal. My goal is to have the grain of the fabric follow a cats hair direction, and to account for the stretch in the fabric. I need the uvs to be proportionate to the model in order to use them for a sewing pattern. I was wondering if there is a way to unwrap uvs to keep them proportionate, while not scattering the islands, so then I can then scale the uvs to match the stretch of the fabric I will be using. I was following seams to sewing pattern, but they don't account for stretch. My other option currently is to rotate and place the islands in Inkscape, which I would prefer not to do. Thanks in advance!
