What would be "realistic" values for gravity, mass and contact material in cannon.js?i've looked in the cannon.js examples, and they seem to mostly use between -10 and -40 for gravity and something between 1 and 10 for the mass of an object (or CANNON.RigidBody as they are called), these demo objects are "well behaved" with these values in that they are just "heavy" enough to overcome gravity and not so "heavy" that they make the ground plane look fake.. by that i mean that i have
