The collision of two actors will behave differently depending on the physics material that is used for each actor.
If I want my actor to slide smoothly past a wall, I make a physical material for the Wall and for the Actor and put both their Restitution and Friction values to 0.0.
But when I put the friction parameter of the wall to a higher value, the Actor no longer slides smoothly past the wall.
What should I do when I want my Actor to slide smoothly against any surface regardless of what their friction parameter is?
