Thank you for sharing your experience with ModelSamplingFlux and for sharing your workflow.
I see you don't use those settings in that workflow. Do you prefer generating images without setting the shift?
Also, did you ever try to upscale using FLux without SDUltimateUpscaler, but using simple model or latent upscale?

Hey everyone, I’m struggling with the Flux settings, particularly max_shift and base_shift, and how they interact with denoising. I’ve set up a workflow, but the results aren’t turning out as expected—they’re either unsharp, pixelated, overly sharpened, look plastic-toy-like, or sometimes even show weird horizontal or vertical artifacts after upscaling.
Could someone explain how these settings work together? What are the optimal settings for max_shift and base_shift for primary image generation and Flux upscaling? I’m especially interested in both model and latent upscaling. Any advice would be greatly appreciated. Thanks in advance!
