I recently joined VRChat and was trying to get a model in game. Figured I'd document my cleanup process for the benefit of the community. Let me know if you like what I'm doing, have. How to clean up messy TinkerCAD mesh for use in Daz Studio. Lukon100 Posts: 235. July 2017 in Technical Help. Clean up the mesh in Blender. Blender has mesh clean-up tools, but I don’t know which to use. And, more importantly, I don’t know which settings to use in Blender to both import and export my model so the results can be used in.
I had asked this question before but on github here , but never got farther into it. Now I have picked it up, and am trying to get this mesh tetrahedralized, but I keep getting errors see below. Ahlthough the statement clearly says 'Found a segment and a subface intersect', I don't know how would I go about resolving that ? The question here is more precisely how to find if mesh has an open boundary and how to locate that and fix that in perhaps blender ? I am asking about open boundary since 'camel.off' which clearly has an open boundary gives the same error. I even tried using another geometry processing tool but it showed no holes found, and its auto repair didn't work either. I get the obj file of Emily 3D scan and remove everything such as eye lashes, eyeballs, inner and outer extra subgeometries. I am using blender to export and using libigl tetgen example to see it if it works. I inspected the mesh, I don't see any holes in the topology, the base hole I fill up using the blender grid fill functionality. See the attached picture. In libigl I launched it in the viewer before processing with tetgen and it looks fine, I also tried all the blender clean up tool, see .
Is there a way to do some more preprocessing automatically before trying to create a tetrahedralized mesh that would ensure smooth operation ? Please advice.

Notice that the lips of Emily has self-intersecting faces. This can be viewed in MeshLab as suggested by @Dominik Mokris. However after deleting those faces, it is hard to get it properly filled without additional faces becoming self-intersecting. See one of the main errors from the tetgen was about self-intersection. The only great tool I found is MeshMixer from Autodesk, in it there is tool called makesolid that takes care of closing the holes and self intersecting faces, etc. Great tool, I can now generate tetgen nicely using libigl !
