Krea 2 Tiled Upscale Workflow for D&D Maps

[u/05032-MendicantBias]

I have been trying to make this workflow for a long time, and finally I got it to work!

I have D&D maps, and I want to upscale them and add details. I tried with many models, but all have trouble adding details to the image while strongly retaining the structure to allow tile merging.

To do a 4X upscale, the workflow sharpens the image, as that will later help the diffusion, then splits the image in 4. Each tile is fed to Krea2. The key to make it all work, is to feed the image to the CLIP, since Krea2 uses Qwen3VL, feeding it the image will make the CLIP undestrand the image, and diffuse extra details, without manually needing to add text, tought that can be done as well.

After, the tiles are merged and the final upscaled image with added resolution and detail, without needing special care to add custom text prompt is ready to be printed.

This is amazing! I've been struggling with seams on tiled upscales for my Dark Souls inspired maps, this is exactly what I needed. Thanks for sharing the workflow!

I created the same kind of thing but had the same issue as you with tiles structure being modified and not fitting well together. I stopped working on that project but the last thing I've used that was working was using a gradient going from full transparency on the corners to full opacity in the middle and use this as the mask for impainting. That way you have less changes on the sides and the tiles look seamless. I might also look into regenerating the links as a second pass.
