I need to trigger a menu-script evaluation every second or less.
How can I do it?

I guess I could use a background event callback like addEventLoopCallback(callback) [www.sidefx.com] , but I don't know how to trigger the menu script evaluation with python.

The menu-script is always triggered when you manually change any parameter of the node. But it won't be triggered when you change the parm with python.

Do you have any idea how to trigger a menu-script evaluation?

Have the same question, want to know it, too.

Hi,

You can call menuparm.pressButton() in Python.

thanks a lot

What about to force houdini to evaluate an ordered menu script which will build a HDA multiparm block?
I tried with different things, can't convinced him to effectually evaluate my menu script..
