Game Concept Art
Iterative visual development using ComfyUI for concept art, character design, environment painting, storyboards, and visual exploration. This skill covers organized workflows for generating, iterating, and managing concept art across game projects.
Infrastructure
ComfyUI runs on a GPU workstation accessible over the network (or locally).
| Detail | Value |
|---|---|
| Web UI | ${COMFYUI_BASE_URL} (default: http://localhost:8188) |
| API | ${COMFYUI_BASE_URL}/api |
| Models | FLUX 1 Schnell, FLUX 2 Klein (4B/9B), FLUX 2 Dev |
| Text encoders | CLIP, Mistral, Qwen 3 (4B/8B), T5 XXL |
| Output dir | Configured in ComfyUI settings (default: ./output/) |
Set the COMFYUI_BASE_URL environment variable to point to your ComfyUI instance. Defaults to http://localhost:8188.
VRAM guidelines: Adjust based on your GPU. A 12GB card can run FLUX 9B at 1024px comfortably; 1536px will push the limit. A 16GB+ card gives more headroom for larger models and resolutions.
