This is an early version of PixelCascade128, a LoRa for Stable Cascade Stace C for pixel art.

Disclaimer: v0.1 can't produce pixel perfect or grid aligned output

How to use

• Only tested on ComfyUI, choose one of the provided workflows (txt2img or img2img)

• Ensure you're using the correct Stable Cascade files (Stage A, B and C, effnet_encoder for img2img)

• Best results are with Stage C/B BF16 weights

How to get the best results

• Use a UNet and CLIP strength of ~1.0 to 0.7

• To force pixel art style use the "pixel art" keyword

• You can use "white background" on negative prompt to remove simple backgrounds

• Downscaling x8 times with nearest neighbors or using Astropulse's Pixel Detector can help to make them pixel perfect

• Works great for 2048x2048 outputs, best results are img2img from a 1024x1024 samples

• Euler a sampler works the best, 20 steps Stage C, 10 steps Stage B

• 2048x2048 samples might generate distorted images, use img2img with 0.7 strength
