I created this Advanced Workflow to fix the biggest problems with Flux. It includes the new NVFP4 support which cuts VRAM usage by 55%, and a GGUF setup for 8GB cards.

What is inside this workflow:

  • The Realism Fix: I optimized the sampler to use the Beta 57 scheduler. This removes that smooth "AI filter" look. (Note: You must install the RES4LYF node for this to appear).

  • Image-to-Edit Mode: A dedicated group to change clothes, transfer lighting, or turn rough drawings into 3D art.

How to use it: I made it very simple. I added a "Fast Group Bypasser" switch.

  1. Select Main Model for high-end GPUs.

  2. Select GGUF for low VRAM (8GB) cards.

  3. Enable Image Edit to unlock the editing features.

Required Custom Nodes:

  • ComfyUI-GGUF

  • RES4LYF (for Beta 57 scheduler)

  • ControlNet Aux Preprocessors
