Hi

Is Example for control pdg from hython?
I dont know how get pdg.node for cook.

If you have a hou.TopNode, you can call:


which will return the pdg.Node associated with the TOP node.

hou.node('/obj/box_object1/topnet1/hdaprocessor1').getPDGNode()

returned None

I need open hip file from hython and cook pdg graph

It returns None because the PDG graph does not exist until the TOP graph is cooked.

The easy way to cook the graph is like so:

Hey chris,
could this command theoretically be sent as a job to basically have a graph execution as job?
Thanks!

Yes, that's basically what the ‘Submit Graph As Job’ button does on the Hqueue and Tractor scheduler nodes.

Thanks Chris!
Is there a reason why that doesn't exist on the DL scheduler? If yes, why?

Support for Submit Graph as Job will be added soon for the DL scheduler.

Awesome! Sorry to interrupt this topic.

Is there a way from PDG to force a SOP node to cook?
A have a python node that takes geo and exports a txt file. All this in SOP land

When i use a filepattern TOP node to collect my geo from folder and a wedge to control some parameters of the graph that ultimately ends with the python node, i cook it and nothing happens.

i need to select a work item and the python node gets evaluated.

Why is this happening and how can i force sop nodes to cook from tops when i am not using TOP nodes for exporting geo or images but my exports are being done in SOPs. I just need the PDG graph to iterate through my 3d models apply some wedges and let the python sop do its thing.

Apart from the python node i have some other nodes as well that export stuff (Houdini to Unity Volume-point cache exporter). i have the same problem with those.

Any advice would be super helpful
