zBone

This node specifies bone-specific attributes.

Attribute

Meaning

enable

When disabled, removes this bone and affiliated attachments from the solve.

collisions

Enables collision detection and response with this bone.

collisionVolume

Vertices from tissues that intersect this bone (provided this bone is a closed volume) will be pushed out if collisions is also enabled.

collisionSets

Only objects that have a shared collision set will collide with this bone. Collision sets are denoted by integers, with all collidable objects initialized inside collision set 0. An empty collision set is equivalent to turning collisions off. Objects may belong to multiple collision sets. Add multiple collision set integers by separating each integer with a space. E.g. To place an object inside collision sets 1, 4 and 5, use “1 4 5”.

contactStiffness

The stiffness of “contact” springs. It controls the “hardness” of the contact between the two objects. Lower values may cause intersections to occur during contact, but will be more stable. Higher values will cause little or no intersection, but may require more solver substeps to be stable.

contactStiffnessExp

The power to which the value of the “contactStiffness” is raised.

contactSliding

When enabled, contacts are resolved with the freedom to slide tangentially. Both bodies in contact need to have contactSliding enabled for this to take effect.
