Float Slider 🐲

ComfyUI's KSampler doesn't come with a slider for its denoise widget, and dragging it by hand is fiddly. Float Slider gives you a proper drag handle for that one value: a 0-to-1 float rendered as a slider, output rounded to three decimals, defaulting to 0.345. It's the "feels nice to use" version of the pack's Float node.

What it does

A number widget displayed as a slider, range 0.0 to 1.0, default 0.345, output a FLOAT rounded to three decimals. The range maps directly onto denoise: 0 is "don't change anything," 1 is "regenerate from noise." The author built it with a stepping of 0.005 so you could hit 0.42 or 0.775 exactly.

Which brings us to the honest caveat, straight from the source: the stepping doesn't work anymore. The code still declares step: 0.005, but as of ComfyUI frontend ~v1.19-1.20, sliders stopped honoring the step - a frontend change, not this node's bug. So the slider now produces whatever continuous value you drag to, and the three-decimal rounding is what keeps the result clean. If you need an exact denoise value, you'll still get a precise rounded number on the output; the "snap to 0.005" behavior just isn't enforced.

How it fits

The pack's number lineup, per the README:

• Float and Float Slider → denoise (0 to 1)
• Float L → CFG (0 to 24)
• Int Slider → steps (0 to 50)

Float Slider is the one you reach for when you're actively experimenting - sliding denoise up and down while watching the img2img output change. When you've settled on a value, the plain Float node is the repeatable version. The author even points to ComfyUI_NYJY if you want a float slider with actually configurable options; this one is fixed-range by design.

Inputs and output

• number - the slider. Min 0, max 1, step 0.005 (in name only, see above), default 0.345.
• Output: a single FLOAT. Wire to denoise on a KSampler.

Installing it

cd ComfyUI/custom_nodes
git clone https://github.com/DraconicDragon/ComfyUI-RyuuNoodles

Restart ComfyUI, or install via Manager (search "RyuuNoodles"). No models, no extra dependencies.

Gotchas

Beyond the dead stepping (which you should know about so you don't report it as a bug), the cap at 1.0 means this is denoise-only - you can't slide to 1.5. And if your ComfyUI frontend is older than ~v1.19, the stepping may still work for you; either way the node functions. It's a slider; there's not much else to go wrong.
