  • Works in 4 steps: asset-optimization PASS → lod-pipeline if LODs required → collision-proxy if physics required → …

  • SKILL.md covers When to Use, Pre-Flight, Recommended Formats and Transform Defaults, plus 6 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Unity Export is an agent skill from arjun988/blender-skills. Unity-specific Blender export for scale, axis, materials, humanoid/generic rigs, LODs, and collision import via MCP.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/unity-checklist.md` and `references/unity-materials.md`).

It sits in Game Development, covering Game development. It works with Model Context Protocol and Blender. The repository describes itself as: 94 specialist Blender skills for Cursor, Claude Code, Kiro & Codex - MCP-powered production pipeline from blockout to engine export. The licence is MIT.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “/unity-export”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. asset-optimization PASS
  2. lod-pipeline if LODs required
  3. collision-proxy if physics required
  4. Apply transforms; correct pivots

What it can do on your machine

Read from SKILL.md and the folder at commit 8f778d2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unity Export loads about 602 tokens when it runs, and up to ~708 if it reads all its reference files. Until then it costs about 32 tokens; SKILL.md has 211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~602
With references · SKILL.md plus every file in references/, read only if the agent opens them
~708

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Unity Export

Unity-ready transforms, materials, LODs, and collision. Prefer GLB/GLTF for modern; FBX for legacy/animation.

When to Use

  • Shipping assets to Unity
  • Humanoid character export
  • Prefab-oriented mesh splits and LODs

Pre-Flight

  1. asset-optimization PASS
  2. lod-pipeline if LODs required
  3. collision-proxy if physics required
  4. Apply transforms; correct pivots
CaseFormat
Static mesh modernGLB
Animated / humanoidFBX
Simple propsGLB or FBX

Transform Defaults

Unit: Meters (Unity 1 unit = 1m)
Forward: -Z (Blender) → verify in Unity
Scale Factor: 1.0 (fix if model tiny/huge)

Materials

  • Prefer single material slots matching Unity workflow
  • Metallic-Roughness for GLTF
  • Embed or provide textures beside FBX
  • Name materials MAT_ consistently

Characters

  • T-pose or A-pose per project
  • Root bone at origin; hips correctly placed
  • Humanoid: clear bone naming; test Avatar mapping
  • Export animations as separate clips when needed

LODs & Collision

  • LOD Group naming: SM_Name_LOD0..N or Unity LOD Group meshes
  • Collision: convex meshes or Unity primitive colliders from proxies
  • See collision-proxy for UCX-style naming if using FBX conventions

Verify in Unity

  • Scale vs reference cube
  • Pivot / prefab placement
  • Normals / tangents
  • Materials assigned
  • LOD transitions
  • Animator clips (if any)

Constraints

MUST DO
  • Validate before export
  • Document scale factor used
  • Test import once before declaring done
MUST NOT DO
  • Assume FBX settings without project convention
  • Leave unused high-poly LODs in prefab
