Sorry if this post seems a little annoying, but i have been trying to find documentation of the ability to change friction values. it was mentioned in the 0.0.5 change log, but i haven't been able to find any reference on how to use it anywhere https://i.gyazo.com/4c8ff0230380ce6f13ec3f437880f16a.png what do i have to put to be able to actually change friction? i am on the dev build so it should be on my version of the game
