KawaiiPhysics is a simple pseudo-physics plugin for Unreal Engine 4 & 5 that animates secondary motion like hair, skirts, and breasts on characters. It works by adding a single AnimGraph node and uses a lightweight custom algorithm independent of PhysX.

Use cases

• animate hair and skirts on game characters
• add jiggle physics to anime-style characters in Unreal Engine
• lightweight bone physics for mobile games
• simulate secondary motion without PhysX
• set up swaying accessories with a single AnimGraph node

When to choose

• you need simple, cute secondary motion for character hair, clothes, or accessories
• you want a lightweight physics solution that runs on mobile and all platforms
• you prefer minimal setup with one AnimGraph node instead of full physics assets
• you need fine-grained control via collisions, curves, and data asset presets

When to avoid

• you need full rigid-body or cloth physics simulation
• your project does not use Unreal Engine
• you require PhysX-based accurate physical behavior
