2🐕Simple slider

Sometimes you don't need a whole "Primitive" node with all its type-guessing, you just need a slider that outputs a number between 0 and 1 - for a LoRA strength, a blend factor, a mask opacity, whatever's next in the graph wants a FLOAT. EG_RY_HT ("Simple slider") is exactly that and nothing more, and it's actually one of the better-known individual nodes in this pack - people specifically ask for "the ergouzi slider" by name when comparing UI-widget options in ComfyUI.

How it works

There's one widget: weight, a FLOAT slider from 0 to 1 in steps of 0.01, default 1. Drag it, and the node outputs that value as a FLOAT. That's the whole node - no min/max customization, no alternate ranges, just a clean, reasonably wide slider bar for dialing in a fraction.

That narrowness is also its known limitation. In a community discussion comparing slider-style QOL nodes, one user summed it up plainly: they liked the ergouzi slider's feel over other options, "but you can't set a custom range for them" - it's locked to 0–1. If what you need is a slider from, say, -10 to 10, this node can't do it; you'd want a different widget or a Primitive with custom range configured.

The inputs and outputs that matter

• weight (FLOAT, required, range 0–1, step 0.01, default 1) - the only input, and it is the value you're producing.

Output is a single FLOAT - wire it into any node with a FLOAT input, most commonly a LoRA loader's strength, a KSampler's denoise, or a blend/mix node's ratio.

How to install it

Search Comfyui-ergouzi-Nodes in ComfyUI Manager, or install by hand:

cd ComfyUI/custom_nodes
git clone https://github.com/11dogzi/Comfyui-ergouzi-Nodes.git

Restart ComfyUI. Worth knowing: the author's README says this English repo isn't being updated anymore, with newer work happening in a Chinese-named sibling pack instead - you're on the frozen version, though for a node this minimal there's not much to break.

Common issues & troubleshooting

You need a range outside 0–1. This is the node's one real, community-confirmed limitation - it's fixed to 0–1 and there's no setting to widen it. For anything needing negative values or a range above 1 (a CFG scale, a custom multiplier), use a standard Primitive node with the range you want, or a different slider widget entirely.

It looks identical to a dozen other float widgets. If you're not sure why you'd pick this over ComfyUI's built-in float widget on a node, the honest answer is UI feel - some people prefer this slider's width and step behavior for fine 0–1 adjustments (LoRA strength, denoise, blend ratios) over the stock widget. Functionally the FLOAT it produces is identical either way.

Step size feels too coarse or too fine. The step is fixed at 0.01 - you can't adjust it on this node. If you need coarser increments for quick scrubbing, you'll be dragging past your target; there's no workaround built into the node itself beyond typing the exact value directly into the field.
