Parameters Overview

Overview of configurable parameters in the KawaiiPhysics node.

Parameter category map

An overview of the main parameters organized into four categories: Physics / Collision / Limits / External Forces. (Diagram labels are in Japanese.)

Parameter Categories​

CategoryDescription
PhysicsBasic physics simulation parameters
CollisionCollision settings
LimitsAngle and movement limits
External ForcesExternal forces like wind and gravity

Quick Reference​

Commonly Used Parameters​

ParameterCategoryDescription
Root BoneBasicParent of the bone chain to apply physics
DampingPhysicsDamping coefficient
StiffnessPhysicsStiffness
RadiusPhysicsBone radius
GravityExternal ForcesGravity direction and strength

Default Values​

// From AnimNode_KawaiiPhysics.h
Damping = 0.1f;
Stiffness = 0.05f;
Radius = 3.0f; // Display name: Collision Radius

Management with Data Asset​

The v1.21.0 KawaiiPhysicsLimitsDataAsset stores collision settings for spheres, capsules, boxes, and planes, along with the Skeleton used for editing. It does not store node settings such as Damping, Stiffness, or Gravity.

Use a dedicated Data Asset for BoneConstraint, the preset planned for v1.22 for node settings, and External Force Presets for external forces.
