LTFloat_Step_001

LTFloat_Step_001 is the 0.01 member of the Latent Tools step-helper family, and it's the one you graduate to when the 0.001 sweeps start feeling like a punishment. It's a calibrated constant: you type a value, it returns the same number as a FLOAT and a STRING, with the widget stepping by 0.01.

This family exists for sweeping a parameter across a batch of images with the seed locked - change one thing per run, compare, move on. At 0.01 per image, a 100-run batch sweeps a full unit, which is a proper range for noise parameters. The trade-off is visible: consecutive images are clearly stepped rather than smoothly interpolated, so it's better for finding the range than for building a smooth animation. Sweep coarse with this, then go fine with 0.001 once you've bracketed the interesting zone.

How it works

The honest version: the node does not auto-increment. It rounds the value you type to five decimals and returns it as a FLOAT and a STRING. The step is the widget's spinner increment and the label for the constant. You bump the value between runs; the node keeps it deliberate.

The inputs and outputs

• value - FLOAT, default 0, range ±1,000,000, step 0.01.
• FLOAT - the value.
• STRING - the value as text, for labeling outputs via a filename prefix.

Wire the FLOAT into a mean/std/cfg input, the STRING into a Save Image filename, keep the seed fixed, and every image carries its own parameter in its name.

Installing it

Part of xl0's Latent Tools pack. ComfyUI Manager → search Latent Tools → install → restart, or:

cd ComfyUI/custom_nodes
git clone https://github.com/xl0/latent-tools

Restart, and it's under LatentTools. The pack's only dependency is lovely-tensors (Manager installs it; manual cloners may need pip install lovely-tensors). No model downloads.
