A growing collection of notes, cheat sheets, and small references made while learning Houdini.

This is not a complete guide to Houdini, and it is not trying to be one.

The goal is to collect useful landmarks: ideas, workflows, and things worth returning to when a project creates a question.

Everything here is made to be practical, clear, and open for anyone who finds it useful.
