Houdini 20.0 Networks and parameters

Node and parameter paths

Every node and parameter has a unique pathname you can use to refer to it.

The organization of data in Houdini is very similar to a UNIX file system.

As in a filesystem, you can use . (here) and .. (up one level) to refer to nodes and parameters by their position relative to the current context. For example, in a sphere node at /obj/geo1/sphere1, you can refer to the radiusy parameter on another sphere node at the same level with ../sphere2/radiusy.



The Translate X parameter of sphere1 inside geo1.


The red color component of the color3 color COP inside COP network comp1.
