Rightclick, break is the option you are looking for. Select the edges and break em, then move the islands apart And you shouldnt need to move points closer, just raise the weld treshold. If yiu set it to 1 you should be able to weld everything in the 0-1 range into one clump :)
Thanks this is much better and more detailed than I was hoping! In picture 3 however how did you manage to, "swing" those set of fingers on the right side though? I don't understand that bit. Do you think you could make a quick video detailing this so I can follow along myself?
Its always the same. Straighten what you want straight, locally relax the rest to follow that straight edge. You could pin it, or like i do, just exlcude it from your selection
Gotcha that makes more sense now, thank you! So I just weld the fingers together, straighten the borders and pin them down, unweld the fingers and then unwrap again right? I'll let you know how it goes!
Strange, it seems to be technically working but not the way you showed us. This is my before and after of welding the verts when I toggle your script, it's not stitching the verts on the fingers together like it does for you for some reason, not sure why.
