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), orvex(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.
Examples
/obj/geo1/sphere1/tx
The Translate X parameter of sphere1 inside geo1.
/comp/comp1/color3/colorr
The red color component of the color3 color COP inside COP
network comp1.
