I'm using the Skin modifier to make the base mesh for a creature, to sculpt on later. But I have some self-intersections, and would like to remove all the internal geometry -- kind of like a boolean union on itself.
Here's a small example, created by using the Skin modifier on three edges of a plane:
I tried the Remesh modifier, but it just kept the internal geometry.
The Intersect (Knife) tool in Self Intersect mode easily selects the boundaries of the interior geometry, but I don't know how to go from there to the interior faces I want to delete.
(I'd upload the .blend file of this example, but I'm not comfortable with blend-exchange's terms. Yes, with this file it doesn't really matter, but it's more of a statement than anything else. I uploaded it to Github's Gist service, but I had to Base64-encode it which means Windows users are out of luck.)
