Filling in holes in terrain meshes... That would have saved me a lot of time a few months ago. Nothing short of magic and voodoo... You always make such awesome tools. I wish I modeled more so I could use them more often. If I ever switch back to modeling full time your site will be one of my first stops.
This looks amazing! can you show this running on a complex concave shape? A covex shape is pretty easy to do by hand. something like this for instance? I regularly model with spline shapes, if this could cleanly cap shapes like above I'd be a buyer.
