My dear droogs,
here it is — my first official custom node pack for ComfyUI (currently at v313), vibe-coded over the past few weeks with Claude.ai. The inspiration came from pixaroma.com, who built a fine pack of his own that lets you handle a lot of the prep work from graphics tools like Adobe Photoshop directly inside ComfyUI. This is the way!
My pack, however, is devoted entirely to LoRAs — implementing them and putting them to work. There are other LoRA nodes out there, like the "Power LoRA Loader" by rgthree, but that one only offers sequential stacking... So I had new merge and trim methods developed, to run many LoRAs at once even on stubborn models like WAN 2.2 — without the image falling apart on me. The keyword: multi-LoRA interference. Claude.ai casually nicknamed it "mush" along the way: AI LoRA porridge. Yeah — we don't want that...
So here and now, you get to group your LoRAs first, before they're merged into one single big model that then flows into the sampler — or samplers (HIGH/LOW)...
Why does that matter? Because different LoRAs overwrite different parts of the actual base model.
Picture a sugar-sweet goth girl posing for a photo shoot in a big-city back alley at golden hour — behind her, a concrete wall covered in graffiti; she has purple hair; she's wearing a black tank top, a black mini dress and ripped tights.
That's the prompt. But those are also the triggers that fire specific custom LoRAs: for the skin, for the hair, for the face of a celebrity like Margot Robbie (greetings to the Overlord!) — or for the clothes, for the lighting like "golden hour" or "god rays", and so on and so forth.
Current nodes merge all of this strictly in the order it was added to the list: indiscriminately, with no emphasis and no sense of what belongs together.
These custom nodes change that.
And the pack has a lot more on board — all of it created "on the fly", mid work-in-progress, born from things that annoyed me. For instance: kijai's WanVideo sampler simply can't be addressed with classic nodes anymore! There are Bridge nodes now that fix exactly that. And example workflows that show you how. There's a multi-model node that lets you handle several models at once via numbered switches. There's a set of analysis tools. And more...
Raise a Moloko Plus to that! And afterwards, a bit of the old ultraviolence!
Your humble narrator, Alex
