PROJECT FOLIAGE ASSETS — created 2026-10-21

foliage-atlas-v1.png
leaf-clusters-v1.png
Generated specifically for The Rookie using OpenAI image generation.
These are generated botanical artwork, not photographs acquired from Poly Haven.
Both assets are 1254×1254 RGBA PNGs with transparency.
The whole-tree atlas contains oak, birch, pine and hawthorn shrub specimens.
The leaf-cluster atlas contains corresponding leafy branches for volumetric crowns.
Generation prompts and provenance: foliage-generation.json.
The game uses alpha testing and crops only the plant interiors; faint transparent edge colours are discarded.

Procedural brick, corrugated metal, gravel, paddock, bark and grass textures are original project code in world.js and trackside.js.
