Unable to export UCX_mesh without UVs or generate mapping coords option ON

Upload scene attached inside 3dsMax.

Scene contains:

1) teapot001 / UCX_teapot001 (with generate map coords option OFF)

2) teapot002 / UCX_tespot002 (wihtout any Uvs)

Export using Datasmith 

 

Import using Datasmith in Unreal

Notice that collision was creating on either if the teapot.

If i was to go back to Max and enable the "generate map coords " on teapot001 export again.

RE-import in UNreal , i will then be able to see the collision.

Same thing for teapot002.
