Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by arjun988 on GitHub. Read the source before you install it.

Installation

Install the Unreal Export AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/arjun988/blender-skills/tree/main/.claude/skills/unreal-export
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/arjun988/blender-skills.git /tmp/blender-skills
mkdir -p .claude/skills
cp -r /tmp/blender-skills/.claude/skills/unreal-export .claude/skills/unreal-export

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Unreal Export in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Unreal Export on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Unreal Export is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Unreal Export

UE-ready FBX. Correct centimeter scale awareness. UCX collision. LOD and socket naming.

When to Use

Static mesh or skeletal mesh to Unreal
UCX/UCLX collision export
LOD chain import
Socket / pivot setup for gameplay

Pre-Flight

asset-optimization PASS
lod-pipeline for LOD0–N
collision-proxy for UCX meshes
Apply scale; pivots at intended UE origin

Scale Note

Unreal is centimeter-based. Common approaches:

Model in meters in Blender, export FBX with unit conversion / 0.01 awareness per project pipeline
Or work to project-documented scale and verify with a 100cm reference

Always measure a known edge after import.

FBX Defaults (Static)


Selected Objects
Apply Scalings: FBX All
Forward: -Z Forward
Up: Y Up
Mesh: ON
Smoothing: Face

Naming for UE

Type	Pattern
Static mesh	`SM_Name`
Skeletal	`SK_Name`
Skeleton	`SKEL_Name`
LOD	`SM_Name_LOD0` …
Collision	`UCX_SM_Name_01`
Socket empty	`SOCKET_Name`

Collision

Prefer convex UCX pieces over complex mesh colliders
Multiple UCX meshes supported
See collision-proxy

Skeletal

UE mannequin-oriented proportions when required
Root bone; no leftover Blender deform leftovers
Export morph targets if needed (shape keys)

Verify in Unreal

Constraints

MUST DO

Confirm scale with known-dimension test
Prefix collision with UCX_
Validate LODs and materials after import

MUST NOT DO

Export without collision plan for physics actors
Mix unit systems undocumented

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Unreal Export AI skill do?

Unreal Engine-specific Blender export for FBX scale, LODs, UCX collision, sockets, materials, and skeletal mesh workflows via MCP.

Why use Unreal Export on TypingMind?

Because you install it once and use it with any model. Unreal Export is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Unreal Export in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/arjun988/blender-skills/tree/main/.claude/skills/unreal-export. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Unreal Export?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Unreal Export?

As many as you like. As long as a model supports skills, you can use Unreal Export with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Unreal Export AI skill free?

Yes. It is published on GitHub by arjun988 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
