Navisworks export plugin tessellation options?

When using the datasmith export plugin for Navisworks (2022) into 4.27 Unreal, I didn’t see any options to change tessellation options (e.g., chord length), so my model is coming in fairly large. In dataprep, the import gear option icon is greyed out in the Inputs panel. Is there any way to adjust num of triangles, either in Navisworks or Unreal?

Hey ScottRT !

The gear icon in Dataprep only applies to CAD files, and Datasmith scenes do not support retesselation.

On the other hand, you can use one or more of the following nodes to optimize your geometry :

  • Create Proxy Mesh
  • Remesh
  • Set LOD Group
  • Set LODs
  • Simplify Mesh

More on what each operation does in this documentation page >> Visual Dataprep Operation Reference | Unreal Engine Documentation

thanks! That makes sense
