Flux.1 S Workflow with Lightning Upscale

Workflow made for Flux1.S model ArtFusion Flux, using the Flux Refiner as upscaler and detailer.

ArtFusion Flux uses only 3 steps for the prep work
Flux Refiner does the finishing touch with 6 steps

This is made because Flux.1 Schnell lacks some details in the skin and often too smooth and shiny.

The amount of influence of the detailer/upscaler can be adjusted with the denoise weight, but 0.2 is mostly fine.

This is one of the only 100% pure Flux.1 S based custom models, so it doesn't have the Dev license.
