I am trying to make a 3D model of a hospital. I want workers and carts (which are of vehicle type) carrying the entity to move between different floors using elevator. The problem is that I have an elevator which itself is made using a vehicle object (taken from Sample Simbit Solutions) and it is transferring only the entity to other floor and the worker/cart stays there only (the reason which I think is that a vehicle object cannot transport another vehicle object).
What can be possible solutions for this?
I didn’t find the right solution from the Internet.
