I try to make a UV map for my object that fits the form of an already existing UV map. I manually positioning the outer edge of the map so it matches the existing map. But the innards are not in good shape.
Now I want to select one of the loops and make the vertices have all the same space between them. I tried to use Looptools but they are not available in UV Image Editor.
How can it be done automatically to even out the spacing of all the inner vertices on a selected loop?
