That will make a mess. He needs to copy and paste also stuff like inertia etc. shift points and so on, weight of the nodes need to be changed too.

I copy the beamng car engine, open the automation engine and then replace values from the beamng engine with automation ones, I might do a full tutorial when I'm home
