I'm working in Blender and Unity.
I downloaded my character from DeviantArt here, used Blender along with this addon to import the character's .mmd file to Blender, and saved her as a .blend file in my Unity project's folder. For some reason, when Unity imported her, her textures weren't appearing, so I created new materials and assigned them to the proper slots on the mesh renderer and she looks the way she should:
Now I'm trying to get my character's clothing physics working. I read online that Unity's Skinned Mesh Renderer and Cloth components are the best solutions, but it recommends that the cloth objects be child objects of the main body mesh. However, the character's clothing that I wish to add physics to (her skirt) is a part of the overall mesh.
So, in Blender I selected all of the vertices that make up the skirt and separated them from the main mesh, then saved a skirt.blend file containing just the skirt, then saved another blend file containing everything but her skirt:
After this process, the textures for the main mesh look just fine in Blender, and the UV data looks exactly the same except for the missing vertices that made up the skirt:
However, when Unity imports these files, it looks like the UV data is corrupted:
What's going on here? How can I fix the UV data for the main mesh?
