Hi,

I keep on getting this feedback in the log when trying to import STEP files with Datasmith. Any ideas what I can do to resolve this?

(UE4.23, standard Datasmith import)

I had the same error when working with glTF imports. Moving to 4.24 preview fixed it for me.

In fact… I was just trying 4.24… Here at least a Datasmith file is produced, but the same error is reported (and zero meshes are imported)

Have you tried the Dataprep workflow? I switched to that after moving to 4.24 as well.

I’m not familiar with that (and the <docs> seem less than helpful). Could you give a pointer? :slight_smile:

Have a look at my post here and the reply further down. You can create a Dataprep asset by right-clicking in the content browser as normal.

Antoine is the goto chap for this sort of stuff. A great guy.

I’ll look into it… thanks for the help!
