Ue5 project setup

UE5 Project Setup Skill

Scaffolds a production-ready Unreal Engine 5 project with all the tooling, conventions, and configuration files needed for efficient AI-assisted development.

What This Skill Creates

1. CLAUDE.md — Project context file for Claude Code integration
2. .gitignore — UE5-specific ignore rules
3. .gitattributes — Git LFS tracking for binary assets
4. Directory structure guidance — Module and plugin organization
5. .claude/settings.json — Exclude noisy directories from Claude context
6. .mcp.json — MCP server configuration for live editor control
7. Config/DefaultEngine.ini entries — Remote Control API auto-start

Step 1: Gather Project Info

Ask the user:

• Project name (PascalCase, e.g., MyActionRPG)
• Template base (ThirdPerson, FirstPerson, TopDown, Blank)
• Primary language (C++ only, C++ with Blueprints, Blueprints only)
• Target platforms (Linux, Windows, both)
• Key gameplay systems (GAS, Enhanced Input, Multiplayer, AI, PCG)

Step 2: Generate CLAUDE.md

Place at the project root. Keep under 150 lines. Use progressive disclosure — tell Claude how to find info rather than listing everything.

# [ProjectName]

## Tech Stack
- Unreal Engine 5.7
- C++ with Blueprint extension
- [List key plugins: GAS, Enhanced Input, CommonUI, etc.]

## Project Structure

Source/ ├── [ProjectName]/ # Primary game module │ ├── Public/ # Headers │ │ ├── Characters/ │ │ ├── Abilities/ │ │ ├── Components/ │ │ └── UI/ │ └── Private/ # Implementation │ ├── Characters/ │ ├── Abilities/ │ ├── Components/ │ └── UI/ ├── [ProjectName]Editor/ # Editor-only module (optional) Plugins/ ├── GameFeatures/ # Modular game features Content/ ├── Blueprints/ ├── Maps/ ├── Materials/ ├── Meshes/ └── UI/

## Coding Conventions
- Follow Epic C++ Coding Standard
- Prefixes: A (Actor), U (UObject), F (struct), E (enum), I (interface)
- Boolean vars: `bIsAlive`, `bCanFire`
- Use `TObjectPtr<>` for UObject pointers
- Use `GENERATED_BODY()` in every UObject-derived class
- `#pragma once` for include guards

## Build Commands
```bash
# Editor build
[UE_ROOT]/Engine/Build/BatchFiles/Linux/Build.sh [ProjectName]Editor Linux Development -project=[path]

# Package
[UE_ROOT]/Engine/Build/BatchFiles/RunUAT.sh BuildCookRun -project=[path] -platform=Linux -clientconfig=Shipping -cook -build -stage -pak

Gameplay Architecture

[Describe your GameMode → GameState → PlayerController → Character hierarchy] [Describe your ability system if using GAS]

Key Classes

## Step 3: Generate .gitignore

Based on the community standard from `github.com/MOZGIII/ue5-gitignore`:

```gitignore
# UE5 Build artifacts
Binaries/
Intermediate/
Saved/
DerivedDataCache/

# IDE files
.vs/
.vscode/
.idea/
*.sln
*.xcworkspace

# OS files
.DS_Store
Thumbs.db

# Compiled assets (if using source assets)
*.uasset
*.umap

# Except for Content (track via LFS)
!Content/**/*.uasset
!Content/**/*.umap

# Build outputs
Build/
Packaged/

Adjust based on whether the user wants to track Content in Git or use a separate asset management approach.

Step 4: Generate .gitattributes for Git LFS

# UE5 binary assets — track with Git LFS
*.uasset filter=lfs diff=lfs merge=lfs -text
*.umap filter=lfs diff=lfs merge=lfs -text
*.uexp filter=lfs diff=lfs merge=lfs -text
*.ubulk filter=lfs diff=lfs merge=lfs -text

# Media files
*.png filter=lfs diff=lfs merge=lfs -text
*.jpg filter=lfs diff=lfs merge=lfs -text
*.jpeg filter=lfs diff=lfs merge=lfs -text
*.bmp filter=lfs diff=lfs merge=lfs -text
*.tga filter=lfs diff=lfs merge=lfs -text
*.exr filter=lfs diff=lfs merge=lfs -text
*.hdr filter=lfs diff=lfs merge=lfs -text

# Audio
*.wav filter=lfs diff=lfs merge=lfs -text
*.ogg filter=lfs diff=lfs merge=lfs -text
*.mp3 filter=lfs diff=lfs merge=lfs -text

# Video
*.mp4 filter=lfs diff=lfs merge=lfs -text
*.mov filter=lfs diff=lfs merge=lfs -text

# 3D assets
*.fbx filter=lfs diff=lfs merge=lfs -text
*.obj filter=lfs diff=lfs merge=lfs -text
*.gltf filter=lfs diff=lfs merge=lfs -text
*.glb filter=lfs diff=lfs merge=lfs -text

# Fonts
*.ttf filter=lfs diff=lfs merge=lfs -text
*.otf filter=lfs diff=lfs merge=lfs -text

# Precompiled binaries
*.dll filter=lfs diff=lfs merge=lfs -text
*.so filter=lfs diff=lfs merge=lfs -text
*.dylib filter=lfs diff=lfs merge=lfs -text
*.exe filter=lfs diff=lfs merge=lfs -text

Step 5: Generate .claude/settings.json

{
  "permissions": {
    "deny": [
      "Bash(rm -rf *)",
      "Bash(git push --force*)"
    ]
  },
  "ignorePatterns": [
    "Binaries/**",
    "Intermediate/**",
    "Saved/**",
    "DerivedDataCache/**",
    ".vs/**",
    "*.uasset",
    "*.umap"
  ]
}

Step 6: Generate .mcp.json for MCP Server Integration

If the user wants Claude Code to control the UE5 editor (spawn actors, create materials, compile blueprints), generate .mcp.json at the project root:

{
  "mcpServers": {
    "ue5": {
      "command": "node",
      "args": ["/path/to/UnrealEngineAgent/mcp-server/dist/index.js"]
    }
  }
}

Note: MCP servers are configured in .mcp.json, NOT in ~/.claude/settings.json (which doesn't support mcpServers).

Remote Control API Setup

Add to the CLAUDE.md template if the user wants MCP integration:

## Remote Control API
- Plugin: Remote Control API (must be enabled in Edit → Plugins)
- HTTP: http://localhost:6766
- WebSocket: ws://localhost:6767
- Test: `curl -s http://localhost:6766/remote/api/v1/objects | jq .`

Add to Config/DefaultEngine.ini:

[/Script/RemoteControlAPI.RemoteControlSettings]
bAutoStartRemoteControl=True
RemoteControlHttpServerPort=6766
RemoteControlWebSocketServerPort=6767

Step 8: Initialize Git Repository

cd /path/to/project
git init
git lfs install
git add .gitignore .gitattributes CLAUDE.md .claude/ .mcp.json
git commit -m "Initial project setup with UE5 conventions"

Asset Naming Conventions (Allar Style Guide)

Asset Type	Prefix	Example
Blueprint	BP_	BP_PlayerCharacter
Material	M_	M_RockBase
Material Instance	MI_	MI_RockBase_Snow
Static Mesh	SM_	SM_Rock_01
Skeletal Mesh	SK_	SK_PlayerCharacter
Texture	T_	T_RockBase_D (diffuse)
Animation	A_	A_Walk_Fwd
Animation Blueprint	ABP_	ABP_PlayerCharacter
Widget Blueprint	WBP_	WBP_MainMenu
Niagara System	NS_	NS_FireEffect
Sound Cue	SC_	SC_Footstep
Data Table	DT_	DT_WeaponStats
Gameplay Ability	GA_	GA_MeleeAttack
Gameplay Effect	GE_	GE_DamageInstant

Output

After running this skill, the user will have:

• A properly structured project root with all config files
• Git LFS configured for binary assets
• CLAUDE.md tailored to their specific project architecture
• A foundation ready for UE5 C++ and Blueprint development
