Three.js Image Generator (OpenAI / GPT-Image)

Purpose

Generate 2D image assets for Three.js games using OpenAI's gpt-image-1. This is a drop-in alternative to the upstream threejs-image-generator (which uses Google Gemini) — same use cases, OpenAI provider. Use whichever your key fits, or run both.

Add-on skill. This skill is maintained in the Phaser fork and is not part of the upstream majidmanzarpour/threejs-game-skills repo. It is purely additive, so upstream updates still merge cleanly. It does not modify the upstream threejs-image-generator.

When To Use

• Concept art and reference sheets (characters, vehicles, props, environments).
• Source images for image-to-3D in threejs-3d-generator (T-pose/A-pose sheets, orthographic views).
• Texture references, sky/background plates, decals, logos, icons, GUI/title/menu art.
• Direct image editing (image-to-image) when the user provides an input image path.
• Transparent-background art (icons, decals, UI marks) via --background transparent.
