ComfyUI-VAE-Utils
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.
Nodes (9)
A Load VAE clone with exactly one job
Disable VAE Offload (VAE Utils)
Latent Upscale (VAE Utils)
Your Wan 2.1 upscale VAE decodes to garbage — this node is the fix
Scale/Unscale Latents (VAE Utils)
Tile Model Patch (VAE Utils)
The decode node for spacepxl's Wan upscale VAE
Visualize Tiles (VAE Utils)
Wan Latent Preview (VAE Utils)
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
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
