When a model is imported into UnrealEngine using the glb/gltf format, it cannot use prefixes such as “UCX_” to generate collision meshes for the engine. It still does it automatically. How to fix it?
Maybe I write something wrong or missed something when importing?
I reproduced your issue, it does not seem normal.
I reported a bug.

Thank you.
Here’s some more details I found about this issues.
• Previously, on the site in the documentation of Unreal Engine 5.2. I found an explanation of importing collisions in glf format. It was written there that all collision import settings are the same as when importing in the FBX format.
OK.
• Found the documentation of collision import in fbx. And repeated all the namings one to one. I named the mesh Tree and its collision UCX_Tree_01. And imported into unreal. In the fbx format, the collision was quietly imported, but not in glf.
• GlTF import settings are default. At the same time, for some reason, the collision is imported by separate meshes from the main mesh. Why is this happening?
• Please explain this dropdown prompt “Import Collision According to Mesh Name”

I got the exact same issue. We depend on glTF because of the better material import but collisions are not imported as collisions.

That is fixed for 5.4.
If you build from source:
- you could try on main already.
- or on 5.3 by cherry picking commits https://github.com/EpicGames/UnrealEngine/commit/250635697fd70374690d2362b56fed3f251dd974 and https://github.com/EpicGames/UnrealEngine/commit/4c64e4d09870b9503632571903df32cf101d50dc
