Asset Generator
Generate PNG images (Gemini or xAI Grok) and GLB 3D models (Tripo3D) from text prompts. These are paid APIs — every call costs real money. Tools live at ${ASSET_GEN_SKILL_DIR}/tools/; run from the project root and keep runtime-loaded outputs under ${RUNTIME_ASSET_DIR}/.
Models
| Model | Flag | Cost | Best for |
|---|---|---|---|
| Gemini | --model gemini |
5¢ (512) · 7¢ (1K) · 10¢ (2K) · 15¢ (4K) | Precise prompt following — references, characters, 3D refs, exact layouts |
| Grok | --model grok (default) |
2¢ | High quality but imprecise — textures, simple objects, item kits, scenic backgrounds |
Grok produces great-looking output but often ignores specific instructions; reach for Gemini when the result must match what you described.
