MassFX for 3ds Max provides a toolset for adding realistic physics simulations to your projectsMassFX simulations use rigid bodies: objects that do not change shape during the simulation. Each rigid body can be one of three typesDynamic: The motion of dynamic objects is completely controlled by the simulation. They are affected by gravity, force space warps, and forces caused by being hit by other objects in the simulation (including cloth objects).Kinematic: Kinematic objects can be animated using standard methods, but do not have to be; they can just be stationary objects. Kinematic objects can affect dynamic objects in the simulation, but are not affected by them. Kinematic objects can be switched to a dynamic state at any time during the simulation.Static: Static objects are similar to Kinematic objects, but cannot be animated. However, they can be concave, unlike Dynamic and Kinematic objects. They can be used as container walls, obstacles, etc.
