Evaluate a parameter, given either an absolute or a relative path to it. Relative path searches are done from the node returned by . This function is a shortcut for hou.parm(path).eval().
Usage
evalParm(path) → int, float, or string
The return type will depend on the type of the parameter.
When a parameter is evaluating, hou.pwd returns the node containing that parameter, so hou.evalParm() can be used inside expressions to perform relative parameter references.
This function throws a hou.NotAvailable exception if you call it from mplay.
