With Collada, I would name objects in a specific way that works, and i would select all Mesh (lod3) objects and export as a group , then same with the phys, and same with Lods.

Now when doing this with GLTF, it's assigning the mesh-to-phys incorrectly, for example it would asisgn "room_door_PHYS" to "room_windows_LOD3" (due to it not having a defined phys shape most likely).

Below is a example of what im referring too

Mesh

-room_walls_LOD3

-room_door_LOD3

-room_ceiling_LOD3

-room_windows_LOD3

Collision/PHYS

-room_walls_PHYS

-room_door_PHYS

-room_ceiling_PHYS

-(i would omit the "room_windows" phys shape per personal preference... the uploader would skip it.

I have 4 files that i can share, but i don't want them public as they're a new mesh build i don't want to publically share
