(datasmith) retesselate creates crash in UE 5.1

Hallo everyone.

I have imported a complet step file with the datasmith plugin. The import works normal, but if i want to retesselate an object, UE 5.1 always crashes.

In UE 5.03 everything works fine an i can retessalate my objects.

Does enyone else have the same problem? Any ideas how to solve it. Or is it a bug?

Thanks everyone how will give me an answer

Hi Pixelschupfer !

This bug with retesselation is a known regression, we’re targeting a fix for 5.1.1.

Thanks for reporting in !

Cheers,
Antoine
