the reason the box component is root is because I can’t use the skeletal mesh as root for the reason that I can’t add a force to it or it will give an error, so that’s how I fixed that error and now it works. If you know any other workarounds, it would be greatly appreciated.
I wonder why epic hasn’t added this yet.
And no, sadly I don’t have an OBJ or OBX file of the plane…
