Hi, Thanks for your great work! When I load this mesh, I found there are some problems with the uv values.

Many verties have the same uv values. When I open the obj in txt format, it looks like this image

The mesh is wrapped by blender smart project. Is it a bug?

<trimesh.Trimesh(vertices.shape=(4425304, 3), faces.shape=(1477200, 3), name="001.obj")> Your mesh is very dense, so slight variations in neighboring UV coordinates are completely normal.

If there are slight variations in neighboring uv coordinates, the slight variations should not cause the neighboring uv coordinates to become the same. I remesh the obj and the uv coordinates become normal now.
