Unity JigglePhysics

A relativistic squash-and-stretch jigglebone physics solution for characters in Unity.

Features

  • Supports per-bone squash and stretch, as well as per-vertex squash and stretch.
  • Realistically relativistic! Elevators, trains, and vehicles won't leave jigglebones permanently trailing behind.
  • Works seamlessly on physics objects without jitter, with no configuration!
  • Supports animated skeletons, JigglePhysics uses it as a target reference pose.
  • Realtime rig scaling support, freely change character proportions on the fly.
  • ScriptableObject-based configuration, share settings across projects and prefabs.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
