To add the list of all these great tips: Experiment with some of max's other tools: including the move and relax brush for local tweaks, it's got strength and falloff settings too. And if you happen to have UnwrapPro, you can define density via vertex colors or soft selection. AFAIK the plugin won't let you lock border…
Look into neox's and dimwalkers suggestions. With a bit of finessing you should be able to fix overlaps. Edit:Rejoice! It looks like you can pin verts with unwrap pro after all =) https://polycount.com/discussion/235489/uv-straightening-and-its-perks-on-lod-generation
Unwrap Pro doesn't seem to respect any verts I pin down in the UV editor, whenever I pin down areas like the eyes or mouth and unwrap again it completely destroys the UV map I made and goes all over the place, not sure if you know of a fix for this?
I already gave you MY solution. I'd not sit there and figure out a smart semi automatic solution for days. I'd just do it. By hand I am personally not using Unwrap Pro. I maybe should give it a go. But this is a company internal guide, not everything in there is done by me personally.
That's so strange, it's not working for me despite following that guide. This is my before and after unwrapping using Unwrap Pro and pinning down some eyelid vertices: As you can see it goes completely nuts and screws up the unfold after I pin down some vertices and hit unwrap again. Even after holding down the space key…
Huh, I have Unwrap Pro actually and it seems to have mostly done what i was looking for. That said I didn't know you could define density via soft selection? So how does that work exactly, I just select the verts in the areas I want more density and then unwrap it or something? The video and page don't really mention this…
