✨ WAN2.1 — Fun control — Simple Workflow
A clean, all-in-one WAN fun control workflow built entirely with the UmeAiRT Toolkit for ComfyUI.
It allows you to use a video to create a sequence that ends at the beginning of the source video, thereby creating a loop.
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-video 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.

I'm getting this error using GGUF workflor:
Invalid workflow against zod schema: Validation error: ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[19].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[27].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[31].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[48].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[52].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[62].properties.cnr_id"; ID can only contain ASCII letters, digits, '_', '-', and '.' at "nodes[66].properties.cnr_id"
any help for this.

I have seen a popup like this since today but it is only a warning and does not prevent generation.
ComfyUI 0.3.33
ComfyUI_frontend v1.19.7
workflow loads and creates normally without any error messages.
try updating to the nightly version
@tmxpdlqmfelvbwjs Thanks for your feedback
an error occurs on the sampler stage 1
SamplerCustomAdvanced
No module named 'sageattention'
But if you disable Sage Attention, then everything works.
The build is completely yours and new
This means that the installation of sageattention has gone wrong. I have a guide that explains how to install it manually: https://civitai.com/articles/12848
@UmeAiRT "Now download triton and put it in a folder" the link is not working. I think because of this, SageAttention will not be set from your build either.
@smolusha you can find triton here : UmeAiRT/ComfyUI-Auto_installer at main
In the scripter version I don't use this link anymore, I forgot to update it in the documentation.
