Error when trying to export/import certain objects

Hi. S4S is trying to tell you what exactly is wrong with the blend but it cannot access its own scrolls with that text.
You don’t need to fix this problem and can find the cause of the issue yourself:
- export the blend from the package in which you are trying to import the blend and open it in the separate window;
- your blend must be structured exactly like this one: have the same number of meshgroups and each of them must be affected by the same vertex groups;
- each meshgroup must have a uv map names uv_0 , exactly like this. You do not need to create uv_1 for objects.

For example, you cloned a decor item made of two meshgroups: the shadow plane underneath and the object itself. The shadow planes will have no vertex groups, so the shadow plane in your blend must have none, too. The object may be affected by transformbone and yours should be as well. And, again, the names of the uv maps. And make sure both meshgroups are visible and selectable, have right cut numbers.

If this won’t help, share the blend and the package please
