Mesh Not Showing Up In S4S

Hi. The mesh does not have a cut number, which is why it is not importing. However, the mesh is not adapted properly, there is no point in importing it in s4s
Other issues:
- the uvs in the uv map are not in the space meant for an accessory;
- there is no uv_1 and no color attribute. If you want the mesh to not morph, you need to vertex paint it with black;
- the mesh in unnecessary high poly, it is best to un-subdivide it;
- in the future, do not transform the mesh in object mode. Switch to Edit mode first, then resize it
