Collada vs GLTF Mesh Import Naming Convention
complete
Tyiler Scarborough
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
-Thanks for your time <3 - Tyiler Scarborough (dynamic evolution)

Dan Linden Hey dan , I managed to figure out th eproblem, I wanted to share with you the results, Im sorry for the delay in my reply
It comes down to a naming convention in blender

Can confirm. Both collada and gltf have a node and a mesh. Collada uses node-name, gltf uses mesh-name.
GLTF probably should use node name as with collada. Any node has only one 'mesh' field, so it should be safe to use node-name. Would aslo help with dupplciate avoidance since meshes can be reused unlike nodes.
