Global Physics Settings Section
Simulation
Determines to simulate physics animations by iClone 6 PhysX or iClone 5 Bullet engine.
Rigid Body
Check these boxes to enable the Rigid Body simulation,
show collision bounding color (red),
and activate the collision detection for sharper and faster speed physics animation.
Soft Cloth
Checks these boxes to enable the Soft Cloth simulation,
bake the physics animation into motion clips,
and decide the reaction range from the surface of a soft cloth during collision.
Gravity
Types values in the X, Y and Z fields to set the gravity direction.
By default, the (X, Y, Z) equal to (0, 0, -9.8), which are the gravity values of the earth in iClone.
World Scale
Drags the slider in accordance to the size of your 3D world.
