--- you need the Flux Refiner model, I tried euler, dpmpp_sde karras, but you'll have to see what works best ---
Added a modified workflow for GGUF, haven't figured out the best settings, so just play with steps and samplers!
Because I don't really like the skin tones and details that come out of the different Flux models, I created an SDXL based refiner for Flux, only tested with Flux.1 S for now, but it seems to work good!
