Everything shoved into single node.
Pros:
Independent of any workflow, can be used anywhere.
Versatile. Can be chained for whatever effect: T2V+I2V extensions (unlimited)+FLF2V loop+V2V Upscale+Face Inpaint, whatever else, in a single workflow.
Cons:
Newbie unfriendly - you have to know what and how Wan does to better understand how to use it.
Lora selection - have to be performed inside the subgraph. Easy to forget and miss when they were used, but also easy to copy to the next part.
Easy to mess up inputs and parameters
RAM bloat - using multiple features with different checkpoint means comfyUI will not unload them from RAM, eventually spilling to swap file. For me, even 128GB is not enough sometimes.
Workflow json file bloat - inner wflow is massive with all the branching.
To start using, select your models (ckpts and lightning loras) inside subgraph (relevant nodes highlighted by red in top left corner), install triton and sageattention, or bypass/remove torch.compile and sageattention nodes (be a quitter and lose ~40% speed boost). Publish subgraphs (book icon) to use anywhere.
When using merges with lightning loras included, bypass or remove lightning lora loaders inside subgraph.
There's a pdf manual in the archive to help navigate subgraph's parameters. Also contains short instruction about triton and sageattention installation.
Changelog
v4 2.11.2025
Combined all Wan 2.2 and 2.1 basic features into single subgaphs.
Gathered most of VACE features into sigle subgraphs.
v3.1 17.08.2025
Added:
FunControl 2.2 - inner wflow and subgraph
Changed:
How loras added; initially i opted to using lora stacks, as only 2.1 loras were availible, to select lora once and apply to both ckpts, but now it's no longer relevant, so back to PowerLoraLoader
FunInpaint was very disappointing, so i won't be adding it. I2V is same in function and has no risk of conflicts with loras.
v3.0 01.08.2025
Added:
Wan2.2 model profiles and new nodes utilizing it's MoE capabilities
Changed:
Group nodes replaced with subgraphs
Removed:
1.3b control loras
v2.8 14.07.2025
Added:
VACE seamless extension - wflow and group node
VACE seamless loop - wflow and node
Removed:
HunYuan
LTX
v2.7 17.05.2025
WanWrapper workflow updated
VACE 14b and 1.3b
Phantom
FantasyTalking
CausVid (3step) lora
Spline dot control example
v2.6 24.04.2025
Wrapper IV2V node - crank up blocks to swap and upscale to XL resolution
FLF2V - official start-to-end frame model that rocks
Skyreels V2 DF - video extention model that takes last frames of provided video and seamlessly extends it - pretty much FramePack, but Wan
v2.5 7.04.2025
Wan wrapper consolidated - separate workflows are likely better, keeping it as proof of concept
v2.1. 4.04.2025
InterpV2V nodes added.
v2. 3.04.2025
HunYuan - standard tools: T2V, V2V, I2V (including LeapFusion), IV2V (performs poorly)
introduction of Group Nodes

seriously need a tutorial on how to actually use this.
This is seriously impressive. It feels like the forefront of where the tech is. I've seen most of this (maybe in simpler formats) in tinkering with workflows I've used, but I didn't even realize you could do some of the things that are in this workflow, like pre-setting the direction for an I2V. This all must've taken FOREVER to chain together- thanks for sharing!
I was looking for a good VACE workflow. I'm still trying to understand and debug some errors I'm getting on the setup (probably just missing something) but I think I just need some time to analyze the workflow better to understand everything on it. It's complex, but I don't see that as a negative. It's clear this wasn't intended to be someone's first workflow anyways. I'm hopeful that once I figure things out though, I'll be good and set. Big appreciation!
Thanks! You're 100% correct, knowledge of both ComfyUI and Wan is required to understand this workflow, and creating group nodes is tedious and time-consuming task.
For VACE make sure you're using resolution divisible by 16 and frame len with remainder of division by 4 of 1 (17,33,49,..). If you're using control video, ensure you pass it's length to VACE node and trim it to required length, if neccesary.
With VACE it's probably impossible to make acually good workflow that will hit everyone's needs, considering how versatile it is. Best one can do is show the basics, some examples and then say -"Now go do your stuff". Understanding it's workings to create your own workflow is more important than finding a fitting one.
Maybe i stupid, but i can't figure out how to install a lot of nodes i missing for this workflow. When i press open node manager, this only showing me one missing node. Every type o press install and relaunch, its ask to install everything again.
If you were installing nodes from 'full+examples' wflow, all nodepacks should be installed, and remaining red ones are group nodes. To fix them, reopening the wflow (closing wflow tab - not browser tab - and openinig again) should be enough. If not, close wflow tab, close browser tab, restart comfy, reopen.
Also, some outdated nodepack that you have and that is used in this wflow, might cause issues.
how to install (vace extender)？my manager can not install it
VACE extender is a group node and is a part of workflow, not a nodepack. Reopen wflow as described in 'First launch' section
cgibson when i use workflow: vace infinte extension,it just stop， and without error message。
but the looping video 4 keyframes is work fine.
cgibson oh the looping video 4 keyframes is work just first video and stop.
cgibson I finally make it，it is great！
