hou.parmTuple function

Find a parameter tuple, given either an absolute or a relative path to it. Relative path searches are done from the node returned by , so hou.parmTuple(path) is a shortcut for hou.pwd().parmTuple(path). Returns None if no parameter exists at that path.

A parameter tuple often corresponds to a two or three parameters on the same line in the parameter dialog. For example, the “t” parameter tuple contains the “tx”, “ty”, and “tz” parameters.

When a parameter is evaluating, hou.pwd returns the node containing that parameter, so hou.parmTuple() can be used inside expressions to perform relative parameter references.

This function throws a hou.NotAvailable exception if you call it from mplay.
