Universal Colliders

Universal Colliders bundles 2 collider generation strategies: CoACD to get accurate convex mesh decomposition (generate in editor), and OBBTree for extremely fast collider generation (runtime).


It allows you to build colliders for non-convex rigidibodies, but also skinned meshes (animated animals, cloth, rope), complex shape, and more. Both modes generate pure Unity convex meshes so you have full control on the generated shapes if you need to tweak them.


Our core philosophy is set and enjoy. You have access to a curated set of controls, and real-time previews. The package is pure C#, no dependencies. It is cross-platform and fast enough to generate colliders at runtime on a phone.
