I have a PhysicsMaterial2D applied to a few colliders in my scene and tried to tweak the friction and bounciness values at runtime. However, I quickly noticed that the values are not reflected in the live simulation. Instead I needed to disable and re-enable all colliders or restart play mode to see the changes. I understand that this may be a limitation of communicating with the physics middleware, but it could also be a bug, so I wanted to ask in the forum. If this is intended behavior I would like to suggest to show a small info text on the PhysicsMaterial2D inspector when in play mode, e.g. "Changes made in play mode will only be applied when affected colliders are toggled.".
