What is Retro Diffusion?
This extension for the popular pixel art software Aseprite allows the easy installation and use of Stable Diffusion AI image generator from inside Aseprite. It also adds advanced features like smart color reduction, and text guided palette creation. In combination with the state of the art pixel model, you can design incredible pixel art pieces in record time.
Game development optimized:
Retro Diffusion is made with game developers in mind, featuring options for tiling assets, and custom palettes. Cut out assets easily with the pixel model having been trained on game assets with a solid black background. Creating game tiles, item sprites, UI elements, characters, and backgrounds has never been this easy!
Custom pixel art AI model:
Retro Diffusion + Pixel Model comes with its own pixel art model, which returns results astronomically better than any competing model or AI. If you have tried to get Dall-e 2, Midjourney, or even Stable Diffusion to create accurate pixel art before, you know that they just don't get it. Check the box marked "Pixel style" and watch as near perfect pixel art is made in seconds. This model especially excels at portraits and character art.

PaletteGen is another custom AI model included in both versions of Retro Diffusion. This model creates color palettes from text prompts. Palettes can be 2, 4, 8, 16, 32, and 64 colors long, and are organized automatically for ease of use.
Automatically take an image from potentially thousands of different colors to just a few, without losing details or composition. Or, choose your own palette to get just the looks you're after.
Do you have a Stable Diffusion model you prefer? You can use it in Aseprite! Go to "Help" -> "Aseprite Diffusion Settings" and enable custom models, then provide the file path. Retro Diffusion will now use that model as the default.
Windows support only for now, potentially Linux in the future if there is demand for it.
I have received several requests for a MacOS version, and I really wish I could fulfill them, but the incompatibility with Mac is a hardware limitation that I can't fix on my own. For now at least, there will be no MacOS support. I will keep my eye on the developments around machine learning on Macs.
Ensure you have the latest version of Aseprite.
On setup, please make sure to read through the installation instructions thoroughly, and are connected to a stable wifi network (mobile hotspots will not work).
6GB of system storage required.
Nvidia GPU support: 10xx series through current series, but must have 4GB+ VRAM (6-8GB recommended). Some cards (namely 16xx series cards) may require you to check an additional box to get running. My 1050 TI did not require this setting, but some 10xx series cards may. If your GPU will not run the script after several attempts, please try using CPU mode which can be enabled post-setup via the "Help" menu.
AMD GPU support: None.
CPU only mode is also supported, but requires 16GB of system RAM minimum. 32GB is recommended.
NOTE: The first generation will take a while on lower end hardware.
