An image of Santa Claus and Krampus.

This was a two-step generation. First, creation of a 1280x720 image. Three columns were used in Regional Prompter; one column in the center that used both Santa and Krampus as a negative prompt to maintain some separation between Santa and Krampus in the image:

Steps: 20, Sampler: Euler a, CFG scale: 7, Seed: 1, Size: 1280x768, Model hash: ebf42d1fae, Model: realmixXL_v15, RP Active: True, RP Divide mode: Matrix, RP Matrix submode: Columns, RP Mask submode: Mask, RP Prompt submode: Prompt, RP Calc Mode: Attention, RP Ratios: “1,.5,1”, RP Base Ratios: 0.2, RP Use Base: False, RP Use Common: True, RP Use Ncommon: True, RP Options: [False], RP LoRA Neg Te Ratios: 0, RP LoRA Neg U Ratios: 0, RP threshold: 0.4, RP LoRA Stop Step: 0, RP LoRA Hires Stop Step: 0, RP Flip: False, Version: v1.7.0-133-gde03882d

The Hires fix upscaler built into Stable Diffusion doesn’t work with a regional prompt, as each tile it works on will have the regional prompt applied to it. So it’s not possible to generate a full-resolution image in a single step.

I took the image and 2x upscaled it to 2560x1440 as a separate step in img2img using the Ultimate SD Upscaler extension:

Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 824048783, Size: 2560x1536, Model hash: ebf42d1fae, Model: realmixXL_v15, Denoising strength: 0.16, Ultimate SD upscale upscaler: SwinIR 4x, Ultimate SD upscale tile_width: 512, Ultimate SD upscale tile_height: 512, Ultimate SD upscale mask_blur: 8, Ultimate SD upscale padding: 32, Version: v1.7.0-133-gde03882d

That produced the final image.
