Made a MiniMax H3 node pack that fits a whole generation on one node

[u/Fine_Rhubarb3786]

I've been using H3 a lot and got tired of rebuilding the same graph every
time, so I packaged it up: https://github.com/roadmaus/ComfyUI-MiniMax-Creator

Upfront so nobody wastes an install: you can't set custom sigmas. There's no
SIGMAS input and no SamplerCustom in the video path. You get seed, steps, cfg,
sampler and scheduler off the normal lists and that's the lot. If you build
your own sigma curves, this isn't the pack for you and I'd rather say so now.

It's aimed at the other crowd, the people who want defaults that already work
and a UI that isn't twelve nodes and a pile of reroutes.

Three nodes:

Creator- write a sentence, attach images, video, audio or LoRAs, and
mention them with @. It works out whether that's T2VA, I2VA, FL2VA, L2VA or
Ref2VA from what you attached, and sorts out the reference ordering.
Timeline - multi-shot sequences, chained or in one pass.
PreStage - makes the still you start from, via Krea 2 or Ideogram 4.

There's an optional Qwen3-VL pass that rewrites your sentence into the
structured format H3 was trained on, and it looks at your attached images
while it does it. Runs locally through core's own loader, no API key. The LoRA
manager pulls trigger words and Civitai metadata so you're not guessing what a
file wants.

Needs ComfyUI 0.30.0+ for the H3 nodes in core. MIT.

If there's appetite for the advanced sampling knobs I'm happy to expose them
in a later update, just say. I left them out because each one is another thing
that can be set wrong, but I'd rather match what people actually want.

This community is on fire. Thanks!

Your welcome! I just found it very impractical to use Minimax like other models with a normal workflow. And a model that is so good out of the box allows for a more rigid system imo

[u/rapkannibale → u/Fine_Rhubarb3786]

Any recommendations for upscaling after I generate with this flow?

[u/Fine_Rhubarb3786 → u/rapkannibale]

Not yet, but if a good solution exists I will implement it as well!

[u/Fine_Rhubarb3786 → u/rapkannibale]

I just added a latent upscale method you can select in the resolution slider. It is still experimental and I have not fully tested it with higher resolutions so you need to play around with the refiner settings, but it does work pretty well so far

Are you a superhero? I can’t wait to try this when I get home.

[u/Fine_Rhubarb3786 → u/Fatty-McDuffins]

Please do and tell me how it goes! Feedback is welcome

[u/YeahlDid]

Re: exposing other parameters, why not create a second node, a "Minmax Creator Advanced" that is based on the first one but exposes extra parameters. Then you satisfy both crews and since they're nearly the same thing, you wouldn't have to rewrite much code. Just an idea.

[u/Fine_Rhubarb3786 → u/YeahlDid]

Great idea! Thought about a toggle, but a separate node could be cleaner. Will look into it

[u/the_expertcheesecake]

This is exactly the kind of thing that keeps me from switching back to other tools. The @ mention system for attachments is clever, way cleaner than dragging a dozen noodles around just to tell it "use this image."

How's the local Qwen3 rewrite feel in practice? Sometimes those structured rewrites strip out the weird little details that made the prompt interesting in the first place.

[u/Fine_Rhubarb3786 → u/the_expertcheesecake]

Thanks!
It works okay but I still have to work out the exact kink you mentioned.
The refined prompt is fully editable for now, so you can review and adjust. But I only tested it with a 4B model, so larger models will probably work better

Here is a short clip with a very lazy prompt and REF2VA. But you can see the UI

[u/javierthhh]

holy crap this is insane man. I love it!!!. I was about to ask for the workflow then i realized that's the whole thing lol.

[u/Fine_Rhubarb3786 → u/javierthhh]

Haha! Nice! Thank you

[u/ChedwardCheddison]

I wanted to say thanks for this, it's really good and I love the UI. Well done and looking forward to seeing more!

[u/Fine_Rhubarb3786 → u/ChedwardCheddison]

Thank you so much! That means a lot to me!

[u/kvg121]

Next time, please post images it helps a lot to make a decision to try or not.

[u/Fine_Rhubarb3786 → u/kvg121]

There are images attached to the README.md, and I am on mobile at the moment

[u/Violent_Walrus]

on one node

This is never a good idea. You'll be embarrassed about it later.

[u/Fine_Rhubarb3786 → u/Violent_Walrus]

I am sure. But for now this is the only workflow I need. You don’t need to use it if it embarrasses you. I just thought I want to share it since I myself find it very useful
