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 meshCollider 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
- Prefer engine primitives when possible
- Mesh colliders: convex toggle for dynamic rigidbodies
- Keep proxy collection exportable
Authoring Rules
- Slightly smaller than visual mesh to reduce snagging (project-dependent)
- No holes; watertight convex pieces
- Apply scale
- Origin aligned with render mesh
- Collection:
COL_Collision_[Asset]
Validation
- [ ] Player cannot fall through intended blockers
- [ ] No huge invisible walls beyond mesh
- [ ] Wheel/character capsules oriented correctly
- [ ] Named for target engine
Constraints
MUST DO
- Prefer few simple shapes over one complex mesh
- Match engine naming conventions
- Keep proxies in dedicated collection
MUST NOT DO
- Use render LOD0 as physics mesh by default
- Non-convex UCX for Unreal auto-convex workflows
