The property you mentioned isn’t modified at all and plus it’s unanchored, maybe I’ll use this info one day
Reducing Friction can help or hinder a moving Parts.
If you want it to move against other Part more easily then reducing the Friction can help.
If you want Parts to have more grip (like vehicle wheels having more traction on roads and less on grass) then you can increase the Friction of the Road Parts or decrease it on the grass.
For your snow you could decrease it quite a bit.
Try increasing the MaxForce number to like (999999999, 999999999, 999999999)
