Meux Seed

ComfyUI went through a phase where the SEED type became a plain integer and every node wanted it in a slightly different flavor. Some want SEED, some want INT, a few stubborn ones want a float. MeuxSeed is the "give me all of them" answer: one seed widget on the input, four outputs carrying the same number in every type ComfyUI cares about.

It's also registered under the alias Seed, matching the name WAS Node Suite uses for the same passthrough - so a workflow that expects the classic Seed node loads with this one satisfying it.

How it works

Dead simple under the hood: it clamps your input to the 64-bit safe seed range (0 to 18446744073709551615) and hands it out in four forms. The clamping isn't decoration - past that ceiling, seeds wrap or behave inconsistently, and this is the "safe" insurance.

Input:

• seed - any integer from 0 to 18446744073709551615.

Outputs:

• seed - the native SEED type, for KSampler and friends.
• number - a NUMBER, for anything that accepts a generic number.
• float - the same value as a float.
• int - the same value as an int.

Pick the output that matches whatever your target node's input type is. If you're unsure, seed and int cover the overwhelming majority of cases.

Installing it

Standard pack install:

cd ComfyUI/custom_nodes
git clone https://github.com/fchangjun/Comfyui_MultiSaveImage
cd Comfyui_MultiSaveImage
pip install -r requirements.txt

Or ComfyUI Manager → search "Baidu Meux ComfyTools" → restart.

Where people get burned

Honestly, this one's hard to burn yourself on. The main trap is subtle and it's the opposite of what you'd expect: this node doesn't randomize. It's a passthrough, so the "new seed per run" behavior comes from the widget's control_after_generate setting, not from anything the node adds. And because it clamps rather than errors, a seed you typed above the safe range silently becomes a different number - which is fine until you're wondering why you can't reproduce that one image.

It's a small tool, but it's the kind of small tool that lives permanently in your template once you've needed it once.
