Hello Jobim,
The datasmith user data are on the actor that is parent of the static mesh actor not directly on the static mesh actor.
This is what I get in 4.27, notice I am selecting the component of the parent actor and looking for user data:
I have a few more metadata on 4.25 so I am checking with our dev if it is normal.
4.26 has some issue with creo import so the part does not come in. Test with 4.25 or 4.27P1 when it will be out.
Let us know if you have all the metadata you need.
Bests,
Flavien.
