Krea 2 · ComfyUI · Pixel Art Studio for Unity

Pixel-Art-Pipeline

Pixel-art character and prop designs from a text prompt, made locally with Krea 2 Turbo and a pixel-art LoRA in ComfyUI, then layered, rigged and animated in Pixel Art Studio, the Unity plugin. It is the pipeline the Pixel Art Studio trailer cast and the two scenes below were designed with.

The installer clones ComfyUI and the ComfyUI-GGUF node at tested commits, makes a Python venv, downloads the six model files (about 13 GB) and checks each SHA-256, and asks before installing the two Claude Code skills. Tested on Linux. Read each model's licence before you download it: the Krea 2 Community License allows commercial use only under US$1M annual revenue. Details, requirements and every licence are in the README.

How it works

  1. Sir Stacks as Krea 2 drew him

    Design

    scripts/krea.py asks Krea 2 Turbo with the 64-grid pixel LoRA for one design: one art pixel per 16 px block. About 7 minutes on a 4 GB GPU.

  2. Sir Stacks on the 64 grid

    Snap to the grid

    The background is removed and the picture is snapped to its grid, then imported into the plugin with the palette matched in Lab.

  3. Sir Stacks peeled into layers

    Peel and rig

    Pixel Art Studio peels the design into layers, fills what each piece hides and proves the stack still equals the design.

  4. Sir Stacks walking

    Animate

    Pieces turn about their joints, frame by frame, by hand or by an agent through the plugin's verbs. The pixel-scene skill holds the method.

Showcases

Every character below started as one Krea 2 design. Everything after it, every frame, tile and effect, was drawn at pixel level and built into real Pixel Art Studio documents.

Pixel Art Studio for Unity

The layering, rigging and animation happen in Pixel Art Studio, a pixel-art editor inside the Unity Editor: layers, indexed palettes and ramps, animation and tags, tiles, rigs and poses, and a scripting surface that agents drive. Its user manual ships inside the package (Assets/PixelArtStudio/Documentation/PixelArtStudio-Manual.pdf), and chapter 25, "Designs from a prompt", walks through this pipeline.
