I have used SmartUV to unwrap my model (a dog cabine) in Blender. It works perfectly fine.
However, the "interior" of the dog cabine occupies a large area of the UVs. I don't want them to take up so much space as the interior will have very little color details. A square of 24x25 pixels would do.
When I scale the islands manually, I would have to scale each other part of the UV as well.
Is there perhaps a function that would re-sort / scale the other UVs (which I have not scaled down manually) according to my changes?
I hope it's clear what I want:
I want to tell Blender that the interior should not occupy so much space, but it should still use SmartUV (which is such an amazing time saver for me).
