Extend Natsura
Natsura is built to be opened up. The core verbs, the mapping framework, the effectors, and the decoration layer are surfaces you build on top of, not closed boxes. This section is for technical artists and pipeline developers who want to go past the shipped nodes and make the toolkit do something it doesn't do out of the box.
It is the most technical part of the documentation. It assumes you are comfortable in Houdini and VEX, and with the way Natsura defers and compiles its graphs (see Simulation for that model). If you are still learning the core ideas, start with Core Concepts first and come back here when the shipped nodes stop being enough.
