As a comic artist, I specifically wanted to create a tool that helped randomize page layout for the benefit of comic artists that would prefer pre-made boxes to fill in with their own art, rather than having to come up with new and interesting layouts every time. As you can imagine, this gets very tiring if you're hundreds of pages into your comics.
I tried other LoRAs but couldn't find a way to get random empty manga page layouts to generate without the boxes being immediately populated by characters, background or text. So this is a mix of my original comic layout training and a couple similar box style LoRAs. I kept training until something useable came out of it. Feel free to use it for any purpose.
My prompts:
Prompt: (((empty manga page, blank page layout))), empty manga panels, panels, dynamic lines, webcomic, manga page, blank page, manga layout, panels, manga panels, page layout, thick lines, sharp lines, high contrast, clean lines, angles, geometry, monochrome (((white boxes with black borders)))
Negative: color, face, person, 1girl, 1boy, people, person, full body, background, face, hair, limbs, body, head, clothes, expression, eyes, nose, mouth, paper, sketchy, wobbly lines, speed lines
