How do I export armature and mesh to UE5?

[Oliver_Noone-Jones]

I have a mesh that has an armature that lets a bone pivot it. This works correctly in blender. When I export it to UE5 it pivots the entire mesh(not what I want). I want to be able to control this bone inside UE5 so I am not animating it.

When I import it all into UE5 I also for some reason get gaps in the mesh in some places.

When I import it to UE5 I get this warning message.

LogWorldPartition: Warning: Actor /Game/ThirdPerson/Maps/ThirdPersonMap.ThirdPersonMap:PersistentLevel.SkeletalMeshActor_UAID_18C04D8E59F0CB3601_1348238911 is unreachable without properly detaching object /Game/__ExternalActors__/ThirdPerson/Maps/ThirdPersonMap/9/23/43CI5TL3HUYFEKV1K23S2E.PackageMetaData in its package

I export it in blender by first selecting the mesh and then the armature.
Then I export with these settings.

I then import to UE5 with these settings.

This is my bone setup.

Does anyone know why this isn’t working propperly and how I can fix it?
I have found working with armatures a pain evey time.

I’m not a blender guy so I don’t really know what armature is except for the brief introduction in the docs.

The gaps are likely due to what’s listed here

I’m not sure what that error is about but could be related. Is that an instance of the skeletal mesh you created above?

Like to try after unchecking “Add Leaf Bones” in the export settings?

[Oliver_Noone-Jones]

The gaps in the mesh only seem to happen when the armature is imported. The whole problem seems to be with the armature. I unchecked leaf bones and that didn’t have the disired effect. Leaf bones allow me to control the bones within UE5. Its a tricky thing to solve because its a problem between blender and UE5. My UVs work well(I have tested with substance painter). Any other ideas?

Though silly, but did you check normals of your mesh?

I am sure your armature is having z axis up in the viewport?

Strange, why is UE detaching the Mesh!

[Oliver_Noone-Jones]

Yea, the normals are fine. After a lot of time seaching I have found out that a blender rig is not quite the same as a UE5 rig. So the things I am trying to do are not working because of how I’ve done it. I’m not quite sure how to get what I want yet but I’ve got a few vidios I’m going to have a look at. Thanks for the help.
