Support structures cannot be scripted. I do not know how to make them from 3ds at all but I can make them amazingly well from supports and free nodes. Then I have to have someone else make the support made structure into 3ds to be scripted. Why can NL2 convert support structures into 3ds like NL1 does? Then I could at least send the 3ds Ferris wheel to someone who can then directly script it instead of having to make 3ds wheel mimic the support and free node made wheel.
I would recommend editing the ties of the overlay track such that they do not cross over the chain lift. The carts would not be able to stay attached to the chain lift if there are cross ties in the way.
