This workflow combines the positive attributes from Chroma and Z-Image without them stepping on each other.
Chroma generates the based image, z-image details the image without destroying it, then it upscales it using Ultra Flux VAE, finally it is detailed further by Z-image in the new high resolution.

The original workflow came from https://github.com/vrgamegirl19/. However the original workflow will absolutely destroy the image, specifically any anatomical detail.
