The LoRA was trained on Flux-Dev.It also works with Flux-Schnell, but I behaves differently.The showcase images are made with Flux-Dev.For Flux Dev I recommend the following setting - Lora strength 0.8-1.0 greatly depending on the image, highres fix with denoising 0.4-0.5The Flux version of this LoRA has a broad range of effect, please try play around with the strength to find out the full range of possibilities
