Upload scene attached inside 3dsMax.
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.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-67180 in the post.
