I want to prepare my scan data.
But there are so many missing parts and the mesh is so ragged I don’t know where to start.
Could you please advise me on how to proceed?
Hello @Tatsuya_Matsushita ,
This will be difficult because not only is the geometry of poor quality, but it is also very thin or even 2D. This means you will not be able to use the Dynamesh feature with this mesh without it breaking apart.
The first thing I would recommend is to use Decimation Master to get the polycount down as far as you’re comfortable with. You may need to manually reconstruct sections of the mesh, and this will be easier to do with lower poly geometry. The Decimation Master process may correct some errors too. Meshes like this have a high probability of reporting problems with Geometry> mesh Integrity> Check Mesh.
If you can reduce the polycount sufficiently, you may be able to put the mesh within reach of the ZModeler toolset which will be useful if you need to manually correct any areas of the mesh.
If you can reduce and clean the mesh, you may then wish to use the Subtool> Extract feature to generate some new geometry from this geometry with a bit more thickness to it.
Be sure to check the mesh for errors with Geometry> Mesh Integrity> Check Mesh after any operations that redraw the topology. It is common for meshes in this state to have those kinds of problems, but you may not be able to correct it until you get the polycount down. After that point, check it periodically as you work with it and fix problems as they may occur.
Good luck!
