✨ WAN2.1 — Text to video — Simple Workflow
A clean, all-in-one WAN text-to-video workflow built entirely with the UmeAiRT Toolkit for ComfyUI.
Only 12 nodes. No spaghetti wires. Just load your model, write your prompt, and hit generate.
⚠️ 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).
🎯 Features
Text-to-Image generation
Automatic download of models in auto version
Built-in SeedVR2 upscaler — high-quality tiled upscaling (toggleable on/off) Slower than a classic upscaler, but significantly better quality
Full metadata embedding — your images are saved with all generation parameters, ready for online publishing and remixing
3 LoRA slots — with individual on/off toggles and strength control and you can connect as many other lora modules to each other for as many LoRA as you want.
📦 Custom Node Required
Only one custom node to install:
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.

Lora stack is still works when set to disabled.
I keep getting the warning message that "CFGZeroStarAndInit" is missing. I can't find this node, despite having installed everything to my knowledge (I also ran UmeAiRT-WAN2.1-Missing_nodes.bat).
I have the same issue
@Megasherru Version 2.0 of this workflow is coming. But for CFGZero this node is native to ComfyUI but currently in the nightly version and not stable.
@UmeAiRT how do we install cfgzero? or nightly? im on version v0.3.27
@UmeAiRT can we just disable the node? the other day it worked for me but after new updates it's missing again.
@pumaai487 Yes you can disable it, it's an optional node
@UmeAiRT Thanks ill give them a try, workflows look awesome and the guides are so organized. Wicked job dude!
