ComfyUI-FunPack

A set of ComfyUI nodes for experimenting with video generation workflows based on WAN, HunyuanVideo, LTX, and similar models.

Installation

FunPack is available on Comfy Registry and can be installed in any of these ways:

1. With comfy-cli: comfy node install funpack
2. With git, inside your ComfyUI/custom_nodes directory: git clone https://github.com/aimfordeb/ComfyUI-FunPack
3. With ComfyUI-Manager: Open Install custom nodes, search for ComfyUI-FunPack, and click Install.

Dependencies

The main FunPack nodes rely only on packages that already come with ComfyUI, so no extra installation is normally required.

hpsv3 is an optional dependency used by the FunPack StoryMem Keyframe Extractor quality filter, so it is not included in the default requirements.

Install it manually only if you need that feature:

pip3 install hpsv3 --no-build-isolation

Important Note About hpsv3

Installing hpsv3 can break Prompt Enhancer and Story Writer, because hpsv3 depends on a transformers version that conflicts with the version those LLM-based nodes require.

FunPack's LLM nodes require transformers >= 5.0.

If you install hpsv3, use --no-build-isolation. Otherwise the install may appear to succeed while the node still cannot detect a working hpsv3 package.

Documentation

Per-node documentation is available in the docs folder.

Version history is available in CHANGELOG.md.
