Greetings everyone,

Is there a way to import physics constraints (ball joint, slider joint,…) of CAD files into UE4? I am using Datasmith to import CAD Data which works fine. But the constraints that were included in the original CAD file (.asm) are gone.

Is there a way to import CAD files inlcuding the constraints??

Many thanks in advance!
