Can't Import Mesh - need help.

Hi. The mesh exceeds the polycount limit and cuts are wrong
- select the skates, add Decimate modifier, reduce Ratio until Face count is at least below 10k, then apply it;

- switch to Edit mode ( TAB), select everything with A, actually assign the mesh to transformbone;
- delete the first two uv maps, then rename UVmap to uv_0;
- delete color attribute as well

- give skates cut 1

- save, clone sculptFloorGEN ( bust ), import your blend and textures there;
- export shadow lods, check how exactly they are made, make new ones.

In the future, do not transform meshes in Object mode
