How to delete parts of an FBX scene in UE5

I have made a simple landscape static mech in blender and have exported it to ue5. I have already exported many models from blender to UE5 for my project but this morning suddenly I have run into a new problem.

When I exported a new version of mt static mesh landscape instead of the 3 part mesh unreal engine duplicated each mesh 1000 times so I have 3000 meshes where I should have 3.

Because of how I have been building my scene, I model the whole scene in blender and then export them in chunks as fbx imported straight into the level, importing the mesh to the content browser and then draging it into the level won’t work due to issues in lining up all of the meshes in the scene.

I have tried to delete the duplicates from the fbx in unreal engine but I dont seem to be able to.

does anyone have any ideas how to delete elements from an fbx scene in ue5? or why my mesh is duplicating suddenly when I import it?

Thanks

Hello there @biggdavid2811!

That sounds like usual shenanigans between Unreal and Blender. Checking around the community, this usually happens when the imported FBX has unapplied transforms, or hidden elements, which UE reads as separated instances, thus creating a ton of duplicated assets.

At the moment, there’s no built-in feature to remove parts of your meshes inside UE, so the best approach would be to fix the problem in Blender first. Please try the following steps before exporting:

  • Apply all transforms

  • Enable “Apply Modifiers”

  • Disable"Add Leaf Bones"

  • Export only your selected objects to avoid any hidden stuff

  • Try importing into the Content Browser as Static Mesh assets

  • If you use world coordinates, they’ll line up in the UE level exactly where they should

  • If necessary, use the World Outliner to filter by mesh name, and delete any present duplicates
