Network 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.

• The root path is /.

• The next level is the list type. This is one of obj (objects), comp (compositing operators), out (render output operators), part (particle operators), ch (channel operators), shop (shader operators), or vex (VEX builder operators).

• Next comes any subnet names.

• Next is the node name.

• You can also specify a parameter name inside the node.

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.
