Hydracept Unity integration

Editor-only package for generating and importing Hydracept production assets in Unity 6.

Install

CLI (recommended)

python -m hydracept integrations install unity

This adds the package to your Unity project Packages/manifest.json.

Package Manager (UPM)

The public UPM release is rolling out. Until v0.1.0 is tagged on hydracept-public, use the CLI install above or add a local path dependency from a Hydracept checkout.

Setup

From your Unity project root:

python -m hydracept quickstart --token <HYDRACEPT_API_KEY> --json

Open Window → Hydracept and click Refresh on the Status tab.

Workflows

Generate sprite

1. Generate tab → enter prompt and dimensions
2. Choose import profile (Sprite, Pixel Art Sprite, UI Sprite, Texture)
3. Submit → import variants when complete

Sheet & Slice

1. Sheet & Slice tab → prompt, grid size, frame size
2. Submit → Import All imports individual sliced PNGs

A succeeded sheet job returns one artifact per cell (not a single contact sheet). See Image production for the API contract.

Imported assets land in Assets/Generated/Hydracept/ with hydracept.provenance.json sidecars.

Boundary

• Editor-only — no Runtime assembly
• No credentials in project assets
• Player builds do not include Hydracept code
• Imported assets work offline after import

Hydracept is a customer of the public API from Unity — not a game-engine inference plugin. See Consumer boundary.
