I'm trying to simply eval an int from a channel in a python partitioner, but seeing as I cant do this on a python partitioner…

import hou
node = hou.pwd()
parm = node.parent('some_int').eval()

Then I'm not sure how to eval any parm/int on the parent hda. in this case pwd will just return ‘/’.

Hacky way is to set the int as an attribute, and pull it that way- but then I'm finding I have to make the partitioner dynamic in order to reliably read that attribute which is not desirable.

Thanks if anyone has a pointer for this.

Thanks to jens for this one. The solution is

Thanks, was just struggling with that this morning!

This has been addressed in tomorrow's daily build of 17.5. hou.pwd(), hou.parm(“../../some_relative_path”), etc should all be working as expected now. If you want to evaluate a parameter with respect to a particular PDG work item, you'll still need to go through PDG's API as mentioned above. For example:

Thanks for getting the hou.parm functionality working for us.
