PIXEL ART with StableDiffusion + Tileset workflows??

Introduction

Creating pixel art using Stable Diffusion can lead to incredible results, especially when combined with various extensions and workflows tailored for pixel-based art. Here’s a step-by-step guide on how to effectively utilize Stable Diffusion to generate pixel art assets and tilesets for your game.

Step 1: Setting Up Your Environment

Download a Checkpoint: Begin by downloading a checkpoint or model specialized in pixel art, such as Pixel Mix by Azip. This model includes keywords like "pixel art" and "pixel world" which are essential for generating relevant outputs.
Install the Pixel Art Extension: Artifacts and stray pixels can be common when generating images. To address these issues, install the Pixel Art extension. Navigate to the settings and enable post-processing, specifically the pixel art option. This will ensure that your images are crisp and properly formatted.
Generating Images: Now you can generate images without artifacts. For instance, when generating backgrounds or character animations, make sure to use the following settings:
- Sampling Method: DPM Plus+ SDE
- Sampling Steps: 10
- CFG Scale: 5
- Clip Skip: 2
Background Generation: To create a seamless repeating background, enable the "Tile X" feature in the asymmetric tiling extension. Ensure that your aspect ratio is 3:1 and that your canvas size is divisible by 8. Avoid using high resolution options as they may distort pixel art.
Color Management: Utilize the pixel art extension's color options. You can lock the colors to have consistent color variation or create a custom palette by importing images from sites like Lospec.

Step 2: Character Animation

Generate Character Sheets: For character animations, utilize ControlNet with pose data. Higher weight values (around 0.85) can help maintain the character’s features during the generation.
Prompting for Animations: Create multiple frames by generating various poses. For instance, use a prompt like "a blonde woman wearing a pink shirt and blue pants" to generate distinct frames of animations.
Refining Generated Frames: Once you have a set of images, you can manually combine them in Photoshop or any image editing tool to create fluid animation sequences.

Step 3: Working with Image to Image

Using Image Inputs: For more detailed image outputs, start with a basic image (like a rough sketch) and process it through the image to image feature. Keep in mind how much of the original image you want to retain while adjusting the noising strength between 0.55 to 1 for more creative freedom.
Color Correction: Adjust settings to include color correction, which helps maintain color consistency between your original sketches and generated images.
Experimentation: Don’t hesitate to experiment with different control models, parameters, and weights to see what combinations yield the best results.
Asset Management: When working with multiple assets, group those that share characteristics. This will streamline the generation process and ensure that unrelated assets do not affect one another.

Summary

By leveraging the capabilities of Stable Diffusion and pixel art workflows, you can effectively create pixel art assets and tilesets for your game. Remember that experimentation is key to achieving the best results, so refine your techniques and enjoy the process!
