$collisionmodel

$collisionmodel options

$mass

• Manually set the mass of the model

$automass

• Tell the physics system to compute a mass for the model, based on it's surfaceprops & volume

$inertia

• Inertia scale

$damping

• Linear damping scale

$rotdamping

• Rotational damping scale

$drag

• Scales the air resistance

$concave

• The vphysics collision model is not a single convex hull. If not set, it'll make a single convex hull out of whatever geometry you give it.

$masscenter

• Override the center of mass, in local coords

$jointskip

• Rarely used. Eliminates a joint in the collision model that you don't want to use. (i.e. if you were using a render model as a ragdoll, and it has bones you don't want)

$jointmerge

• Merges the vertex assignments for two joints.

$rootbone

• The parent-most bone that actually has collision geometry.

$jointconstrain

• The limits of the joint's movement

$jointinertia

• Like $inertia, but per-bone

$jointdamping

• Like $damping, but per-bone

$jointrotdamping

• Like $rotdamping, but per-bone

$jointmassbias

• Mass is automatically distributed by volume, this lets you bias it per-bone

$noselfcollisions

• Turns off all collisions between bones in this model, usually for performance.

$jointcollide

• If any $jointcollide pairs are specified, only those joints collide with each other.

$animatedfriction

• Used to animate the amount of friction on joints over time.
