Feature Samples

Not Officially Released

This feature has not been officially released yet. It is planned for KawaiiPhysics v1.22. Specifications may change during development.

Hair may keep swinging, clothing may pass through the body, or wind may look too uniform. When investigating these problems, a finished Animation Blueprint alone can make it difficult to separate the settings responsible for the motion.

The development sample groups exhibits into nine themes, with dedicated Animation Blueprints you can open from each exhibit. Choose the behavior you want to investigate, inspect its settings and result, then use that as a starting point for your character. This guide is for artists tuning hair or clothing and technical owners examining combinations of settings.

Themes

What you want to improve	Start with	Watch for
Hair keeps swinging after movement stops	02_PhysicsSettings	How quickly the tip settles; compare Damping and Stiffness separately
Hair or cloth passes through the body	03_Collision	Shape placement and clearance during the same motion
Wind looks too uniform	08_Wind	Root-to-tip timing, changes in strength, and gusts
An action needs a temporary motion change	06_RuntimeControl	Entry into the effect, its duration, and the return afterward

For a finished character, inspect the related part's ABP in 09_Showcase, then return to a single-feature exhibit to separate the factors involved. The nine themes include existing features; they are not all additions introduced in v1.22. You can also choose from the Feature Samples Reference.

Actual sample screenshot reused from the Portal, showing an older exhibit layout. Find the Damping/Stiffness rows to compare one setting at a time; the World Collision panel compares OFF and ON. This is not a v1.22 nine-theme screenshot.

Levels

Purpose	Content location
Original sample level	Content/KawaiiPhysicsSample/L_KawaiiPhysicsSample
Exhibits by theme	Content/KawaiiPhysicsSample/Examples/
All themes in one place	Content/KawaiiPhysicsSample/L_KPS_AllExamples

The combined level loads the themed levels side by side. If you know what to investigate, open the corresponding theme and inspect the exhibit's Animation Blueprint.

Exhibit Navigation

Open Content/KawaiiPhysicsSample/L_KPS_AllExamples or a themed level, start Play (PIE), and give the viewport keyboard focus.

Key during PIE	Action
Z / X	Previous / next exhibit within the current theme
PageUp / PageDown	Previous / next theme
H	Open the current exhibit's documentation in the Portal
B	Open the current exhibit's Animation Blueprint in the editor

In the editor, the sign actor's Details panel also provides Open Docs / Open AnimBP buttons. Signs show Japanese when the current language is Japanese and English otherwise. The sample configures its own documentation links; these do not necessarily all lead to these preview pages.

Sample Exhibit Examples

Actual Portal image used in the v1.17 changelog. Top right compares AnimNode/DataAsset/PhysicsAsset sources; bottom left compares force spaces; bottom right compares skirt collision setups. Its Sequencer label is an older exhibit, not evidence of the new v1.22 multiplier track.
