Early Access — AI Forge is built and actively used by a solo developer to create AI Legends (a horror fantasy MMO). New features, tools, and services are shipping continuously. I haven't had the chance to test everything yet — please join the Discord to give feedback, report bugs, and help shape the product.

Built by Hurtz Donut Studios — a solo indie studio proving that one person with the right AI pipeline can build at AAA scale.

What Is the AI Forge MCP Package?

The AI Forge MCP Package is a subscription software toolkit that gives AI coding agents — Claude Code, Cursor, Windsurf, and any MCP-compatible client — full programmatic control over the professional 3D game asset pipeline. It is the most comprehensive MCP solution for Unreal Engine 5 and Blender automation available today.

Instead of a human artist manually clicking through menus in five different applications, an AI agent calls tools like clean_mesh, texture_glb_asset, generate_rigify_rig, or export_fbx_ue5 and the software executes automatically. The AI handles the entire workflow: generate a concept, create a 3D mesh, clean it, rig it, animate it, texture it, apply materials, generate dialogue, sync lipsync, and deliver a game-ready asset into Unreal Engine 5 — without a human touching the DCC tools.

This is not a Blender plugin. This is not a UE5 marketplace asset. This is a full-pipeline orchestration layer that treats the entire 3D content creation stack as a unified, AI-controllable system.

Who Is This For?

• Solo indie developers who want AAA-quality assets without hiring a team of artists
• Small studios looking to multiply their output by 10x with AI automation
• Game jammers and prototypers who need production-quality assets fast
• Technical artists who want to automate repetitive pipeline tasks
• Anyone using Claude Code for game development who wants purpose-built MCP tools instead of writing fragile scripts from scratch

ForgeRoom — Desktop App & Web Console

50-Agent AI Studio

AI Forge includes 50 specialized AI agents organized across 10 departments that can work concurrently on your game:

Lead Agents (Claude Opus — 4 agents): Sovereign (orchestrator), Warden (security), Architect (project planning), Forgemaster (asset pipeline lead)

Specialist Agents (Claude Sonnet — ~35 agents): Sculptor (mesh), Alchemist (materials), Bladedancer (combat animation), Worldsmith (environments), Dreamweaver (narrative), Luminary (lighting), Voiceshaper (dialogue/lipsync), Renderer (quality), Visionary (creative direction), Sentinel (security monitoring), and more across Art 3D, Animation, Engineering, Game Design, and Audio departments

Support Agents (Claude Haiku — ~12 agents): Quartermaster (inventory), Benchmark (performance), Grinder (batch processing), Gatekeeper (quality gates), Foundry (asset processing), Archivist (documentation), Conduit (pipeline routing), Bastion (security enforcement), Herald (notifications), Oracle (knowledge base), and more across QA, DevOps, and Marketing departments

Customers choose their team size based on workflow: 3 agents for focused work, 10 for steady production, or 50 for maximum throughput. No feature gating — team size is your choice, not a paywall.

The 16 MCP Servers

Total: 565 tools | 16 servers | 248,000+ lines of production code

ForgeAnimHelper — Animation Blueprint Automation (New)

AI Forge includes ForgeAnimHelper, a custom UE5 C++ Editor plugin (1,169 lines) that enables full AI automation of Animation Blueprints — something no other AI game dev platform can do.

ForgeAnimHelper exposes AnimGraph and Event Graph manipulation to Python, allowing the MCP pipeline to create complete Animation Blueprints in a single tool call: state machines, blend spaces, locomotion setups, transition conditions, and Event Graph variable caching — all wired automatically.

The plugin supports transition condition parsing (Speed > 10.0, bIsInAir, !bIsInAir, AutomaticRule), per-bone blend profiles, sync groups, and full compilation with error reporting. Four bridge tools in GameForge (wire_abp_animgraph, wire_abp_event_graph, create_complete_abp, compile_abp) connect the C++ plugin to the MCP pipeline.

9 Workflow Knowledge Documents (New)

AI Forge now ships with 9 comprehensive workflow documents (~260KB total) that serve as pipeline reference guides for the AI agents:

1. AI Enemy Pipeline — Behavior Trees, Blackboards, Gameplay Ability System, ragdoll integration
2. Advanced Asset Pipeline — Retopology, baking, texturing, rigging, LOD chain generation
3. Horror VFX Techniques — Blood, chains, fog, organic horror effects with Niagara and Blender
4. Game Systems Blueprint — Combat, inventory, loot tables, quest systems, dialogue trees
5. Multiplayer Setup — Actor replication, Epic Online Services, net frequency tuning
6. Cinematic Pipeline — Level Sequencer, cameras, lighting rigs, post-processing
7. Optimization Guide — LOD strategies, Nanite, draw call optimization, profiling
8. Blender Simulation — Cloth, hair, fluid, rigid body, ocean simulation workflows
9. Animation Blueprint — ABP architecture, ForgeAnimHelper automation, template fallback workflows

How It Works — The Full Pipeline

The AI Forge MCP Package automates the complete asset creation pipeline from concept to engine delivery. Here is every step:

Step 1:  Concept Art Generation ............. Grok (xAI) generates reference images
Step 2:  3D Mesh Generation ................ Hunyuan3D (Tencent) creates geometry from concept art
Step 3:  Mesh Cleanup ...................... ForgeBlender removes loose geometry, merges doubles, fixes normals
Step 4:  UV Unwrapping ..................... ForgeBlender verifies and optimizes UV layouts
Step 5:  Texture Enhancement ............... ForgePainter bakes mesh maps + ForgeDesigner builds procedural materials
         (fallback) ....................... ForgeBlender cinematic enhancement if Substance unavailable
Step 6:  Rigging ........................... ForgeRig auto-generates skeleton via UniRig AI
Step 7:  Weight Painting ................... ForgeBlender optimizes weights — edge loops, pruning, symmetry, deformation testing
Step 8:  Animation ......................... ForgeMotion generates locomotion (HY-Motion) + combat (AnimationGPT)
Step 9:  Animation Blueprint ............... GameForge + ForgeAnimHelper auto-wires ABP with state machines and blend spaces
Step 10: NPC Dialogue & Lipsync ............ ForgeNPC generates dialogue, ForgeVoice creates lipsync animations
Step 11: LOD Generation .................... ForgeBlender creates multi-level-of-detail chain for performance
Step 12: UE5 Delivery ...................... GameForge imports into Unreal Engine 5 with materials, LODs, and collision

Input: A .glb file + a reference image + a plain-English description of what you want.

Output: A fully rigged, textured, animated, lip-synced, UE5-ready asset with LODs, collision, Animation Blueprint, and proper material setup.

The 7 AI Backends (Including NVIDIA ACE)

This pipeline integrates seven AI systems, each handling what it does best. We believe in full transparency about what powers the work.

Grok by xAI — Concept Art Generation

All reference images and concept art can be generated using xAI's Grok. High-quality visual direction that feeds directly into the 3D pipeline. Used commercially under X/xAI Terms of Service with attribution.

Hunyuan3D by Tencent — Text/Image to 3D Mesh

Takes concept art or text prompts and produces raw 3D geometry. Open source under MIT License. Handles the leap from 2D reference to 3D model automatically.

UniRig by VAST-AI Research — AI Auto-Rigging (SIGGRAPH 2025)

GPT-based auto-rigger that predicts skeleton hierarchies and skin weights from raw meshes in seconds. No manual bone placement needed. Published at SIGGRAPH 2025.

HY-Motion by Tencent — AI Locomotion Animation

1-billion parameter DiT model trained on 3,000+ hours of motion capture data across 200+ movement categories. Powers all locomotion: walking, running, jumping, climbing, swimming, flying. Open source.

AnimationGPT — AI Combat Animation

Combat-specialized motion model with 8,700 combat animations and 26,100 text annotations tagged by weapon type, attack type, speed, and power. Generates contextual combat sequences from plain-English descriptions.

NVIDIA ACE — NPC Intelligence & Voice

NVIDIA ACE powers the NPC dialogue system (ForgeNPC) with personality profiles, contextual responses, and interrogation trees. NVIDIA Audio2Face (ForgeVoice) generates lip-sync animations with emotion classification. NVIDIA Riva provides speech-to-text and text-to-speech for real-time NPC voice interaction.

Claude by Anthropic — Pipeline Orchestration

The AI coding agent that ties everything together. Claude reads the pipeline configuration, calls tools across all 16 MCP servers, makes creative decisions based on the reference image, and delivers finished assets. Claude is the creative director — the MCP servers are its tools. With the 50-agent studio, Claude powers an entire team of specialized AI agents working concurrently on your game.

Species-Aware Animation Profiles

The AI Forge MCP Package includes 16 built-in species animation profiles that automatically adjust movement physics based on creature characteristics. The AI does not need manual configuration — the system reads the species profile and adapts all animation parameters automatically.

How it works: Each species profile defines height, weight, stride length, movement speed, center of gravity, limb proportions, and physics properties. When the animation system generates movement for a 15-foot ogre, it automatically produces heavy, lumbering footfalls with ground shake. When generating movement for a 5-foot elf, it produces fast, agile, light-footed motion. The same text prompt — "run forward" — produces physically different animations for every species.

10 Playable Species Profiles: Human, Elf, Dwarf, Orc, Ogre, Troll, Goblin, Undead, Demon, Dragon-Kin

6 Creature Profiles: Wolves/Canines, Bears/Large Quadrupeds, Serpents, Avian, Arachnids, Elementals

Each profile is customizable. Customers can modify existing profiles or create new species with their own physical characteristics, and the animation system adapts to match.

5 Asset Pipelines

The package supports five distinct asset production pipelines, each with specialized tool chains:

Characters (Playable)

32-bone extended skeleton with finger bones, bilateral symmetry enforcement, anatomical proportion validation, facial rig for lipsync, full locomotion + combat animation suite, automatic Animation Blueprint with ForgeAnimHelper.

Creatures & NPCs

24-bone skeleton, species-specific animation profiles, weight class physics, NPC dialogue generation, personality profiles, lipsync support for speaking NPCs.

Weapons

Geometric correction (blade straightening, symmetry enforcement), rarity-tiered material complexity (common through legendary), grip alignment for character hand bones, physics properties for combat animation.

Armor

Slot-based system (head, chest, legs, feet, hands, shield), material-type classification (metal, leather, cloth, bone), high-poly to low-poly bake workflow, proper weight painting for character deformation, equippable clothing system in UE5.

Environments

Enterable buildings with wall thickness, door and window cutting, stair generation, interior geometry, modular building kits, PCG-based settlement generation, landscape integration via UE5 PCG, proper lightmap UVs for static lighting.

Key Stats

Technical Requirements

Required (Free)

• Blender 4.0+ — Download (free, open source)
• Unreal Engine 5.3+ — Download (free until $1M gross revenue)
• Python 3.10+ — Download
• Node.js 18+ — Download
• An MCP-compatible AI agent — Claude Code, Cursor, Windsurf, or any client supporting the Model Context Protocol

Optional (Improves Quality)

• Adobe Substance Painter — Professional texture painting and mesh map baking
• Adobe Substance Designer — Procedural material graph authoring
• Adobe Substance Sampler — Photo-to-material scanning
• Autodesk Maya — For studios with Maya-based pipelines
• SideFX Houdini — For procedural generation and VFX workflows

The pipeline works without Substance, Maya, or Houdini. The Blender-native cinematic enhancement path produces excellent results on its own. Additional DCC apps elevate the quality further when available.

Optional AI Backends (Free, Open Source)

• UniRig — AI auto-rigging, requires NVIDIA GPU with 8GB+ VRAM (GitHub)
• HY-Motion — AI locomotion animation, requires NVIDIA GPU with 24GB+ VRAM
• AnimationGPT — AI combat animation, requires NVIDIA GPU

Hardware Requirements

Important: The AI Forge MCP Package itself uses zero GPU. It is a tool orchestration layer — lightweight Python processes communicating over stdio. The GPU requirements listed below come entirely from the third-party software the pipeline controls (Blender, Unreal Engine 5, UniRig, HY-Motion, Hunyuan3D). If you already run Blender and UE5 on your machine, you already meet the requirements.

Minimum (Blender + UE5 pipeline, no local AI generation):

• GPU: Any GPU that runs Blender 4.x and UE5 (GTX 1070 / RX 5700 or better)
• VRAM: 4GB+
• RAM: 16GB
• Storage: SSD with 30GB+ free

Recommended (Full pipeline with AI backends):

• GPU: NVIDIA RTX 3080 or better (CUDA required for UniRig and HY-Motion)
• VRAM: 8GB+ (24GB+ for HY-Motion locomotion generation)
• RAM: 32GB minimum, 64GB+ recommended
• Storage: SSD with 50GB+ free space

The MCP servers themselves run on CPU and use minimal resources (~50MB RAM per server). GPU load comes from Blender rendering, UE5 viewport, and optional AI backends — the same GPU load you'd have using those applications without AI Forge.

The Proof of Work — AI Legends

AI Legends is a horror fantasy MMO being built entirely by the AI Forge MCP Package. Every asset in the game — characters, creatures, weapons, armor, environments — is produced by this pipeline. It serves as the living proof that the system works at production scale.

AI Legends demonstrates the full capability chain: Grok generates concept art, Hunyuan3D creates 3D meshes, ForgeBlender cleans and optimizes geometry, UniRig auto-rigs skeletons, HY-Motion and AnimationGPT generate movement and combat animations, ForgeAnimHelper auto-wires Animation Blueprints, the Substance suite handles materials and textures, ForgeNPC creates dialogue, ForgeVoice generates lipsync, and GameForge delivers everything into Unreal Engine 5.

One developer. One AI pipeline. One game.

Competitive Landscape

There is no comparable product on the market. Individual components exist — Blender MCP plugins, UE5 automation scripts, standalone AI rigging tools — but nothing chains the entire AAA pipeline under unified AI control from concept art through engine delivery. The closest alternatives require human operators at every handoff point between applications.

The AI Forge MCP Package eliminates those handoffs. One AI agent, one conversation, one prompt — and a game-ready asset comes out the other end.

Security & IP Protection

AI Forge uses an 8-layer security chain to protect both our pipeline IP and your game assets:

• Source code compiled via Nuitka — Python compiled to C, then to native binary. Customers get full functionality, never source code.
• Pipeline docs served to AI context only — Documentation and agent prompts are fetched from the cloud at session start and held in the AI's memory. Never written to disk. Never cached locally.
• JWT auth with rate limiting on the context delivery API — prevents bulk scraping or unauthorized access.
• CLAUDE.md directives — Technical layer that prevents AI agents from extracting or reproducing pipeline internals.
• TOS legal prohibition — Contractual enforcement against reverse engineering, extraction, and replication.
• Hardware fingerprint binding — Each license is tied to the customer's machine.
• 24-hour license heartbeat — Compiled binaries validate the license on startup and every 24 hours during operation.
• Forensic watermark — Exported assets contain an invisible watermark tied to the customer's license key, enabling trace-back if assets are leaked.
