Fill hole in mesh (not missing faces, but "real" hole)

[Loukana]

Hello,

I’ve got a small problem, but couldn’t find the answer anywhere. I need to clean scanned meshes with really bad topology, and filled with holes (image below). Until now, I’ve been using the “Insert sphere” tool to close them, before doing dynamesh and zremesher, but this tool is not really precise and adds a lot of bumps I need to smooth afterward. Using “Pinch” causes problems afterwards with the dynamesh, as I sometimes get non-manifold geometry where the thickness of the mesh is too small (vertices form opposite sides are merged together).

Is there another tool or another method which could allow me to fill these hole ?

Thanks in advance.

Inflate is what I use, but that is the same idea as insert sphere.

you can try masking the whole thing and then play with “extract” in the subtool palette. it’s not a way of closing holes, but it might give you another platform from which you can get new ideas on how to clean it up. project all might also help out, like maybe projecting the details, bad ones and all, from the scanned mesh onto a good mesh, the areas that had holes won’t project anything so the good mesh shouldn’t have any holes, then clean that one up.

Thanks for your answers. I tried Inflate and Extract, but it still isn’t working as good as I want…

I already use Project All further in my pipeline to transfer the original’s details on the cleaned and subdivided version, but when the original has those holes and the cleaned one doesn’t, the Project All causes vertices to “explode” in those places. That’s why I want to remove those holes before doing anything else.

What I would need is the possibility to add matter, a bit like the clay brush, but which could update the geometry while doing so (like doing a local dynamesh after each brush stroke). When the two sides of the hole are near enough, they are blended together. I don’t suppose there’s already a functionality like this ?

you’re talking about something like dynamic tessellation. no zbrush does not have that. but sculptris does. you can use Goz to back and forth between the programs.

There is a close holes button in the geometry pallette.

Yes, I agree with Doug. Close holes is the best and easier solution. No need to reinvent the wheel here. I use close holes all the time.

close holes isn’t going to do anything in his case. He has physical holes in his geo, not missing faces.
