Texture doesn't connect with UV on S4S

To be imported, your item must be visible, selectable, have the right cut number. To function as intended, it must be adapted like an object you’re replacing. In the scene you will find two or more objects: an object itself, a shadow underneath. Both have different cut numbers. Your object must have the same one as the original object. It should also be assigned to the same bone. So select the original object, check the cut number, delete this item;
- File - Append - the blend file with an object you made - Object - the object itself, append;
- give it the same cut number;
- create a new bone with +, double-click to name it transformBone. In edit mode select all of your mesh with A and click on Assign;
- rename the uv map to uv_0. Duplicate it with +, name uv_1;
- select the shadow underneath and adjust it to fit your mesh;
- save, import back




It does not matter where you create your object, but it is a good practice to always do things like this:
- find a similar object in the catalog, clone it, export the blend;
- study how the object is adapted (number of meshgroups, what bones affect it, whether it has uv_1 or color attributes)
- create your object here and adapt it the same
