Download the model diffusion_pytorch_model.safetensors
from https://huggingface.co/Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro/tree/main
rename it to something like flux-dev-controlnet-union for easier identification,
and place it in the ControlNet folder, for example: ..ComfyUI\models\controlnet

I am using flux GGUF check Ep10 to see how to install that https://www.youtube.com/watch?v=Ym0oJpRbj4U

Get one of the Flux Dev Models (recommended to use Q5_K_M or larger for the best results, Q4 for 12gb VRAM) - My favorite is Q8

Place it in the unet folder ..ComfyUI/models/unet
