Skill: Art Pipeline (nano banana as input generator)
Objective
Use nano banana to generate inputs (concept refs, mood boards, modular parts) while keeping final game assets deterministic via templates + palettes.
This repo does not accept “AI images dropped directly into game/assets” as final art.
What nano banana is allowed for
- Mood boards for biomes (to derive palettes)
- Concept sheets for props/characters (to guide modeling)
- UI style exploration (boxes, typography, icon language)
Where outputs must go
All generated images must land under:
art/source/ai/nanobanana-output/
Prompting patterns (examples)
Biome mood board (Bubblegum Bay)
- Goal: palette direction (NOT final textures)
- Prompt template:
- “Landscape-only JRPG biome mood board, low-poly toon, 4-band shading feel, playful pastel seaside town, calm ocean blues, candy accents, no text, 6 panels.”
Prop concept sheet
- “Turnaround concept sheet for a low-poly toon prop: , simple shapes, clean silhouettes, no text, white background, 3 views.”
UI exploration
- “Turn-based JRPG UI mockup, top HUD with portraits and HP/MP bars, bottom command menu boxes, cozy kid-friendly, no cassette theme, no text labels.”
Next step (convert to deterministic assets)
After generation:
- Extract palette candidates (tools/python)
- Build the prop/character in Blender using templates
- Bake sprites/backgrounds via scripts
- Validate outputs
Acceptance checks
- Any nano banana output used in production must have:
- a recipe stub referencing it
- a deterministic conversion step (Blender bake or modeling)
