collision-proxy
Collision proxy authoring for games including UCX/UHX naming, convex hulls, capsules, and simple collider meshes in Blender via MCP.
npx skills add arjun988/blender-skills --skill collision-proxy --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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 - Prefer engine primitives when possible - Mesh colliders: convex toggle for dynamic rigidbodies - Keep proxy collection exportable ## Authoring Rules 1. Slightly smaller than visual mesh to reduce snagging (project-dependent) 2. No holes; watertight convex pieces 3. Apply scale 4. Origin aligned with render mesh 5. Collection: `COL_Collision_[Asset]` ## Validation - [ ] Player cannot fall through intended blockers - [ ] No huge

What does the collision-proxy skill do?
Collision proxy authoring for games including UCX/UHX naming, convex hulls, capsules, and simple collider meshes in Blender via MCP.
How do I install it?
Run `npx skills add arjun988/blender-skills --skill collision-proxy --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From arjun988/blender-skills, a repository with 71 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
