✨ 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.

Hello,
it is really strange with version 2.0 on my rtx 4070 12GB i have no OOM, even when i say 60 steps 96 frames
same settings on 2.1 and i get 99% of OOM even if i decrease a lot the frames or steps.
Any clue why ?
What i liked in 2.1 when i managed to get it working was then tensor upscale and that there are more "optimization options"
sometime i'm really lucky and it works without OOM (nothing else that comfyui is running) and i got a new seed want to try again and boom...
Even with the previous seed not possible to make it run anymore :/
going back to 2.0, no single OOM :/
Note: you need to install the custom nodes for ComfyUI-GGUF for this to work. Otherwise, no matter what you do UnetLoaderGGUFDisTorchMultiGPU and DualCLIPLoaderGGUFMultiGPU won't load.
BUG for v2.1 (2.0 Works fine)
got All your ComfyUI nodes are missing required inputs, like vae_name, expression, format, frame_rate, noise_seed, sampler_name, etc.
same issue described detailed here https://civitai.com/models/1363672
If you have installed the mixlab nodes, delete them and see if the problem persists.
On Mac M4, I've got following error at frame-interpolation.
How to fix it ?
RuntimeError: Expected all tensors to be on the same device, but found at least two devices, mps:0 and cpu!
Very very very good 😍, I liked it a lot, it would be great to add a node to polish the prompt, such as the "TIPO" node 😗
These are excellent workflows and are now my daily workhorses. All my vids are currently being produced with these. I get excellent performance and also love the preview step to decide if i want to continue with a generation to completion.
