# Open3DForge

> **Personal AI-powered image-to-game-ready 3D asset pipeline**
> Built for solo game development. UE5-first. Runs on HF ZeroGPU.

A solo-developer tool for generating special/custom 3D assets (characters, unique props) that can't be sourced from Fab or Megascans. Generation → cleanup → UV unwrap → PBR baking → LODs → collision → optional rigging → engine-ready export.

## Pipeline

1. **Generate** — TRELLIS.2 (hard surface) or Hunyuan3D-2 (organic) from 1-4 input images
2. **Post-Process** — repair, decimate, UV unwrap (xatlas), bake normals/albedo/materials/AO (nvdiffrast), inpaint hidden UVs (SDXL), LODs, collision (CoACD), pivot, scale
3. **Auto-Rig** — UniRig for character skeletons
4. **Export** — UE5 FBX bundle with DirectX normals + ORM packing

## Hardware

Runs on **HF ZeroGPU H200** (70GB VRAM, 25 min/day on Pro). No local execution path — HF Spaces only.

## Status

🚧 Active development — Milestone 1 (foundation) in progress.

See `PLAN.md` for the full architecture document.
