This is a pixel art lora that focuses on playing nice with automated, non-AI post-processing.

Recommended/Optional: It works well with the Pixel Grid Helper [ComfyUI Registry] [GitHub] custom nodes, which I developed specifically for this mode.

Use this Lora with 0.8-1.0 strength, and always set the size to 768x768. The output will be a 128x128 image, scaled up to 768x768. Scaling it down using nearest neighbour should be fine in almost all cases. (The 'Pixel Grid: Median Fixer' node however checks each 6 by 6 square and applies the median color to all the pixels to iron out minor artifacts.)

Use the trigger word pixel_6x6.
