【FLUX】MEGAPACK — v4.0

LoRA tester

⚠️ IMPORTANT — Nodes 2.0 Required

This workflow is built for the Nodes 2.0 (Vue) interface of ComfyUI. If you don't enable it, the workflow may have display problems.

How to activate Nodes 2.0:

Open ComfyUI

Go to Settings (⚙️ icon, bottom-left)

Find "Use Nodes V2 (Vue)" and toggle it ON

Refresh the page

Load the workflow

If you prefer the classic interface, check out my Legacy version of this workflow instead ( link ).

📦 Custom Node Required

Only one custom node to install:

👉 ComfyUI-UmeAiRT-Toolkit

Install via ComfyUI Manager (search "UmeAiRT") or use the UmeAiRT Auto-Installer . The Toolkit packages everything internally — upscaler, face detailer, metadata saver. No other custom nodes needed.
