Documentation

README

Excerpt

Collision Proxy

Simple, stable colliders. Prefer primitives and convex pieces over render mesh.

When to Use

Game physics / blocking volumes
Unreal UCX export
Unity mesh or primitive colliders
Hitboxes for interactables

Workflow

Identify collision needs → Build proxies → Name correctly
  → Test overlaps → Export with render mesh

Collider Types

Type	Use
Box	Crates, walls, simple props
Capsule	Characters, poles
Sphere	Balls, soft approximates
Convex hull	Organic / irregular single body
Multiple convex (UCX)	Vehicles, complex props

Unreal Naming

UCX_SM_Asset_01
UCX_SM_Asset_02

Must match associated mesh naming rules for auto-association
Convex only for UCX

Unity Notes
