Sloth Studio – AI 8-Direction Walk Cycle Sprite Generator

An AI 8-direction sprite generator for game characters. Give MoveLab one character image and it makes walk and run cycles in all eight directions, then exports them as a transparent sprite sheet you can import into Unity, Godot, GameMaker, Phaser or any other engine. It suits top-down, isometric and RPG games.

No subscription and no credits: it's a desktop app you pay for once, and it uses your own OpenRouter key.

How it works

1. Upload one reference image. MoveLab makes a clean, front-facing character from it.
2. It turns your character to S, SE, E, NE, N, NW, W and SW, keeping clothes and proportions.
3. Each direction gets a walk cycle or run cycle that starts and ends on its still frame, with the background removed and the edges outlined.
4. Export everything as transparent PNG frames in one zip. The zip includes an LLMS.txt that tells your AI coding agent how to loop, resize and clean the frames for your engine.

The sloth on this page is real output from the app: an 8-direction walk cycle and an 8-direction run cycle, at 24 fps.
