Node Parameter Comparer

● Node Parameter Comparer is a Python tool for Houdini that compares parameters of two nodes and displays only the differences.

● Why do I need it?

When you have two similar nodes with dozens (or hundreds) of parameters, finding differences manually is painful. This tool does it in a second.

● Features

- Shows only different parameters — identical ones are hidden

- Checkboxes to select specific parameters

- Copy in either direction: A → B or B → A

- Copy selected or all parameters with one click

- Displays expressions when present

- Ramp parameters hidden by default, toggled with a checkbox

- Full Undo support — one Ctrl+Z reverts everything

- Table auto-refreshes after copying
