Thanks Danny. Sorry I should have mentioned above that when I said I pulled the STEP file into Unreal Studio, it was using the Datasmith import. This is the reason it got imported so well in my mind because clearly they have put in a lot of effort to more intelligently import meshes and materials. I would like them to go further with some of the features mentioned above, but I was curious what other people had experienced and what their workflow was. Thanks for replying man. All the best
