Rhino Datasmith into one Static Mesh for AR

Hi there, apologies if this comes as a newbie question…

I have a Rhino (architectural) model with different elements referenced in different layers by material type. I exported via Datasmith.

When I try to bring into BP_Placeable in HandheldAR template, I cannot seem to bring the model into the space as one MergedActor without countering issues in compiling the script. It’s as if I needed to create the model as one StateMeshActor.

I have tried looking across forums for understanding how to combine collectively as one static mesh (which I think is what I need to solve the problem) but this seems hard to find without requiring a degree in blueprinting.

Appreciate any help! :smiley:
