Datasmith is not combining meshes from groups/components, as specified in the documentation, thus leaving me with a HUGE number of meshes and slowing down tasks like importing, saving and baking lights.
The file in question gives 92K actors in Unreal 4-5. The same file gives me 27K actors when importing through Twinmotion.
Can anyone help me?
Can you give a link towards “combining meshes from groups/components, as specified in the documentation” ?
The two things I would look at is:
- did you use instancing as much as possible
- you might need to use some dataprep recipe to merge elements on import base on rules
Using Datasmith with SketchUp Pro | Unreal Engine Documentation
As said, under “Converting Geometry into Static Meshes”:
“Datasmith divides your SketchUp geometry into Static Mesh assets by combining all connected polygon faces that are in the same component or group, into a single Static Mesh. Knowing this strategy can help you influence the Static Meshes it creates.”
I believe instancing is fine, as Twinmotion reads it correctly…
I could do Skp > Twinmotion > Unreal, but the problem is that Twinmotion messes UVs up, so it’s too much rework to fix it
" * you might need to use some dataprep recipe to merge elements on import base on rules"
I’m not sure how to do that, would appreciate any help
Thanks
