Thanks for your further replies everyone, they've been quite helpful. I am in fact using Paint Shop Pro and have succeeded in getting the desired results by using the methods suggested above. So to be clear then, paint program image manipulation is the only way to get that non-gridded transmap template, and I shouldn't bother trying to get UV Mapper to output the file that way initially, correct? Also, a slightly off-topic yet related question. In Paint Shop Pro, is there no way to use the kind of flood-fill that was common in older paint programs? The kind where it fills with the color but automatically stops as soon as it hits any other differently colored pixel? So that if I had an empty white rectangle with a black border, and I filled inside it, it would only fill to the border and then stop by itself? That used to be very easy to do and still is in simple apllications like MS Paint, but I see no way to do it with PSPro. You can select a limited area to be affected by a fill, but that's useless if your desired area is of a weird or unorthodox shape. Any tips? Thanks again!
