What does a sprite sheet generator do?

It produces the frames of a game animation from a source image. The workflows here generate individual animation frames or a full multi-frame sheet from one uploaded picture.

What input do I need to provide?

A single image of your character or sprite. The style transfer workflow additionally takes an outline reference and a style reference image.

Which animations can it generate?

The Sprite Sheet Generator workflow returns frames for idle, attack, walk, and jump animations, and the single-image workflow produces a general animated sequence as a sheet.

Can the sprites match my game's existing art style?

Yes. The Game Asset Style Transfer workflow uses your style reference to generate new 2D sprites that match, which suits background and set-dressing assets in 2D and 2.5D games.

Are the results ready to drop into a game engine?

You get standard image output: separate frames or an assembled sheet. Slice and import them with the sprite tools in Unity, Godot, or any other engine; the workflows do not emit engine-specific atlas metadata.

Which models power these workflows?

They are built on Google's Nano Banana image models: Nano Banana 2 for the single-image sheet and Nano Banana Pro for the frame generator and style transfer.

Do I need to install anything to try them?

No. The Try button opens each workflow on Comfy Cloud and it runs in the browser; a local ComfyUI install is only needed to run the graphs on your own hardware.

About This Workflow

What is the AI Sprite Sheet Generator?

A sprite sheet packs the frames of a game animation into one image, and drawing those frames by hand is the slowest part of 2D game art. This page's workflows generate the frames for you: upload a picture of your character and the Sprite Sheet Generator returns individual frames for idle, attack, walk, and jump animations, while the Single Image to Animated Sprite Sheet workflow lays a multi-frame sequence out as a ready-to-crop sheet.

New sprites also have to sit next to the art a game already has. The Game Asset Style Transfer workflow takes an outline reference and a style reference and produces 2D sprites that match, which makes it a fast way to fill out background set dressing in a 2D or 2.5D scene without the new pieces looking pasted in.

Each generator here is an editable ComfyUI graph built on the Nano Banana image models. Run them from any browser on Comfy Cloud or inside a local ComfyUI install, swap the source image or prompt, and re-run until every frame stays on-model. Generation is quick enough that iterating on the character design costs minutes, not the days that redrawing a sheet would.

Comparison

Why Comfy Workflows

Editable graphs, not black boxes

Every generator is an open ComfyUI workflow, so you can change prompts, models, and frame handling instead of accepting fixed output.
Animation and style in one place

Frame generation and art-style matching sit on the same page, covering both new characters and assets for an existing game.
Cheap to iterate

A re-run takes minutes, so you fix an off-model frame by regenerating rather than repainting.
Cloud now, desktop when needed

ONLY ONComfyCLOUD

Everything on this page opens directly on Comfy Cloud; the identical graph files also load into a desktop ComfyUI.

Applications
