So I have a 3d scan of a face, pictured:
And it has no thickness whatsoever, I'd like to add some so that it can be 3D Printable (my printer can handle the vrml/obj format and tons of colors). I've tried solidify but it puts a bunch of cracks through the face:
And I've tried using the bisect tool, then hitting f to fill the holes while what I bisect'ed was still selected, and all of the holes won't fill. I've also tried some of the solutions from this question: How to make a perfectly flat bottom for 3D-printing topographic relief? but it creates those same cracks.
Any ideas? I'm sorry if this has been answered somewhere else.
