Do beams have collision?

I still learning how nodes and beams interact, i know that nodes collide and that beams connect the nodes and help them to react such as pulling other nodes during a crash, but I'm not sure if beams only interact with nodes are do they also interact with the world?

 

Only coltris and nodes can collide with the world/other cars.

 

Ok thanks good to know, but what is a coltris?

 

Coltri is short for collision triangle. I believe it is a flat plane formed by beams that has aerodynamics and (obviously) collision.

 

A coltri is a collision triangle made up of three nodes that have to be specified in a counter clockwise rotation in order to work properly.
There are also colquads which are the same thing but with 4 nodes.
