AP3-to-Illustrious Pixel Relay Upscale Workflow

AP3-to-Illustrious Pixel Relay Upscale Workflow A toy two-stage ComfyUI workflow made for myself that uses Anima Preview 3 to create the base image, then uses Illustrious SDXL to upscale and refine it. The main idea is to keep AP3 focused on what it does well: caption following, scene setup, and multi-character interaction . At the same time, it avoids relying on AP3 for high-resolution diffusion refinement, since its official recommendation is to stay around the ~1MP range and image quality can degrade at higher resolutions. In this workflow, AP3 generates the initial base image . The image is then passed in pixel space to the second stage, where the upscale model handles the actual image enlargement , and Illustrious SDXL redraws/refines the enlarged image through UltimateSDUpscale. This avoids pushing AP3 beyond its comfortable resolution range while still taking advantage of Illustrious’s stronger high-resolution redraw, background rendering, and detail refinement .
