run python script from button in node


Recommended Posts


I made a python script that runs from the shelf. I'd like to have the script run when I press an update button created in a node. Looked at the callback function but can't figure out how to get it to work.

Hope someone can help

cheers Coen

In the "scripts" tab of your hda add a PythonModule and put your function there, e.g. def runMe()

In your button callback, enter hou.pwd().hdaModule().runMe()

Better if you take a look at the mdd writer hda at http://undo.fi/houdini/mdd/ - it has a button set up that runs a script.

There might be better ways to do it, but at least that works for me :)

thanks eetu,

starting to make sense now. But is that only suitable for digital asset? Just trying it on a null now and the method doesn't seem to work
