FunPack is a UI that unlocks novel conditioning and sampling enhancements, wires cutting-edge techniques and allows simple non-linear video montage - all while using regular ComfyUI backend. Graphs replaced with neat cards, get/set replaced with Linked inputs, and simple text fields leveled up to Composer - prefix, prompt, postfix, $variables, Ideas button, shortcuts and splits - for your prompting comfort.
Important
FunPack is a hobby project maintained by a single person. It's crafted for my personal needs mostly, and I can't test every single possible variant of usage to confirm it's bug-free and working as intended. If you had found a bug or you want to request a new feature, feel free to add an entry to Issues - that would be the most appreciated.
Preparation for the next milestone update v4.0.0 has been started and it is in progress.
Since v4.0.0 all updates will target ONLY Cutting Room editor. Nodes will receive updates but their compatibility and proper display inside regular ComfyUI frontend won't be guaranteed and/or tested.
Feel free to test and leave feedback regarding v4.0.0 by switching branch to "v4" via internal feature inside "Settings" -> "Updates and ComfyUI" -> "Switch branch".
FunPack is available on Comfy Registry and can be installed in any of these ways:
- With
comfy-cli:comfy node install ComfyUI-FunPack - With git, inside your
ComfyUI/custom_nodesdirectory:git clone https://github.com/digital-garbage/ComfyUI-FunPack - With ComfyUI-Manager:
Open
Custom Nodes Manager, search forComfyUI-FunPack, and clickInstall.
FunPack includes a requirements.txt file for its Python dependencies.
Install them with:
pip install -r requirements.txt
FunPack uses your existing ComfyUI/PyTorch install. The expected baseline is transformers >= 5.0.0
