## Description

Generate game assets, locally and free by default with godogen_assets: images and transparent PNGs (Qwen-Image), textured GLB models (TRELLIS.2), rigged humanoids with generated moves and lip-synced speech, sound effects and voice lines. Paid APIs cover what the local tools can't make, Gemini / xAI Grok images, animated sprites from video, Tripo 3D, Gemini TTS voice acting, Lyria music. Use whenever a game needs generated art or audio.

# Asset Generator

Assets come from [godogen_assets](https://github.com/htdt/godogen_assets): local generators on this machine's GPU, one command per task, free. Its checkout here is `${GODOGEN_ASSETS}`, and its docs are the reference; this page is the TL;DR plus what the game needs on top. Read `${GODOGEN_ASSETS}/README.md` once (conventions, a character start to finish, checking results), and a part's README up to `How it works` before first using its tool.

| Command | Makes | README in the checkout |
|---------|-------|------------------------|
| `qwen-image` | PNG from text; `rgba`: real transparency; `edit -i ref.png`: image-to-image | `image/` |
| `gen3d` | textured GLB from an image | `mesh/` |
| `mia-rig` | Mixamo-rigged humanoid from a GLB | `rig/` |
| `add-moves`, `gen-moves` | idle/walk/run/jump onto a rig; custom moves from text prompts | `motion/` |
| `grip-prop` | a prop made holdable; `add-moves --hold` puts it in a character's hand | `motion/` |
| `lipsync` | speaking mouth + lip-synced clip from a voice line | `lipsync/` |
| `stable-audio` | sound effects, seamless ambience loops | `sfx/` |
| `qwen-tts` | voice lines from a description, or cloned from a reference line | `voice/` |

A character: `qwen-image rgba` (T-pose) → `gen3d` → `mia-rig --fingers --anim none` → `add-moves`, with `gen-moves` for custom moves and `lipsync` for speech. Props stop after `gen3d`; one a character holds goes on through `grip-prop` and `add-moves --hold`, never by an offset tuned in the engine.
