Nodes for loading and using VAEs in ways not supported by base ComfyUI. Currently supports Wan upscale VAE, more may be added later as needed.
|
|
|
|
## Install
|
|
|
|
```
|
|
cd custom_nodes
|
|
git clone https://github.com/spacepxl/ComfyUI-VAE-Utils
|
|
```
|
|
|
|
That's it! No extra requirements outside of what ComfyUI already uses.
|
|
|
|
## Models
|
|
|
|
[Wan2.1 VAE 2x imageonly real v1](https://huggingface.co/spacepxl/Wan2.1-VAE-upscale2x/blob/main/Wan2.1_VAE_upscale2x_imageonly_real_v1.safetensors)
|
|
|
|
## Nodes
|
|
|
|
### Load VAE (VAE Utils)
|
|
|
|
Direct replacement for native Load VAE node, but with added input/output channel detection for Wan2.1 VAE
|
|
|
|
### VAE Decode (VAE Utils)
|
|
|
|
Decode latents with optional auto detected upscaling, and optional tiling
|
|
|
|
### Latent Upscale (VAE Utils)
|
|
|
|
|
|
|
|
Simple neural latent upscaler (right), far from optimal but much better than naive bilinear/bislerp interpolation (left).
|
|
|
|
Currently supported: Wan2.1 2x
|

## IMPORTANT
|
|
|
|
To use native VAE decoding with latents from kijai/ComfyUI-WanVideoWrapper, you need to un-normalize the latents first using this node:
