Nested OTLs and kwargs

[GeordieM]

Hi all, I've got a chain of nested OTLs and would like to call Python functions held in a lower level OTL from a higher level one.

 

Example graph:

 

obj/OTL_A/OTL_B/grid

 

OTL_B's pythonModule has a function:

 

# OTL_B Function

def setGridSize(gridSize):

    curNode =  hou.node(".")

    curNode.node(".\grid").parm("sizex").set(gridSize)

#

 

I then have a button callback in OTL_A that calls:

hou.node("./OTL_B").hdaModule().setGridSize(10)

 

I know there are betters ways to achieve this functionality using exposed parms but just making an example.

 

The issue is that the call to hou.node(".") inside OTL_B returns OTL_A.

 

I've read The threads about the differences between hou.node("."). hou.pwd() and kwargs["node"] and I understand I should use kwargs["node"] like this (I think):

 

# OTL_B Function

def setGridSize(gridSize):

    curNode =  kwargs["node"]

    curNode.node(".\grid").parm("sizex").set(gridSize)

#

 

The real problem is that kwargs["node"] does not exist.  The kwargs dictionary exists but only has a "type" key.  I believe kwargs["node"] works correctly from within callbacks but what about being directly called in a function?

 

TNKS!

Pass the node that calls this function into this function directly from callback as a second parameter, instead of trying to get it inside of it.
