Authoring: Fracture

Use point clouds to make a destructible prim through fracture.

Installation

To use this Node, you must enable source in the Extension Manager.

Inputs

Name	Type	Description	Default
execIn	execution	Input execution
prim	bundle	Prim to use as input to fracture. Connect to destructible output from another Blast node or output from an import USD prim data node.
points	pointf[3][]	Point cloud to use for fracture. Points inside will be used as Voronoi sites, points outside will be ignored.
contactThreshold	float	Force from impact must be larger than this value to be used to apply damage. Set higher to prevent small movements from breaking bonds.	10000.0
interiorMaterial	token	Path to material to use for interior faces created through fracture.
maxContactImpulse	float	Force that PhysX can use to prevent objects from penetrating. It is only used for kinematic destructibles that are attached to the world. This can approximate brittle materials by setting the value low, giving the bonds a chance to break before the objects are pushed apart.	10000.0
interiorUvScale	float	UV scale to use on interior faces generated through fracture.	1.0
impactDamageScale	float	Scale physical impacts by this amount when applying damage from collisions.	1.0
allowSelfDamage	bool	If on, chunks from a destructible actor may cause damage to sibling actors. Default behavior for legacy assets is to disable self-damage, which changes the legacy behavior.	False

Outputs
