When changing an env var from the Aliases and Variables window, the scene instantly updates automatically to reflect that variable change anywhere it was being used.
But when changing the same env var with setenv in HScript or hou.putenv, the scene does not update. I've also noticed it takes a few seconds to reflect that change in the Aliases and Variables window if you have it open while changing it.
What is the correct way to force the scene to update after changing an env var like this?
thank you!

Thanks. So if I use an FBX Character Import SOP to get the skeleton and then feed that into an Agent From Rig SOP, how would I add an arbitrary channel to that skeleton to later use with blendshapes on geometry used as an Agent Layer?

I am bringing in an FBX character through an Agent SOP and then adding different layers to that agent with an Agent Layer SOP.
How can I add blendshape channels to these layers? I'm using these agents in a crowd system and want to modify the blendshape channels in the sim, but can't figure out how to add a blendshape channel to an agent layer.
Both the Character Blend Shapes SOP example hip and everything I've been able to find online makes blendshapes in an OBJ subnet rig, but I can't figure out how to do this in my setup.
Thanks!

Hi Seelan,
I believe I have found the issue. It was something in our houdini wrapper / launcher messing up DEADLINE_PATH.
thanks for your help!

OK, so submitting it manually in a shell works fine. The verbose logging output this:
And running this command successfully submits the job:

I've turned on Verbose Logging but don't see anything more being printed anywhere. Where does it log to?
A regular cook (dirty and cook) works fine, the graph is just a generic generator going into a python script that prints the hostname.
A pdgtemp directory gets created in the working directory I've set on the deadline scheduler with these folders and files inside:
I'm attaching the hip as well.

Trying to get Deadline Scheduler running and am getting this exception:
I'm not sure what file it's looking for that it can't find. The graph cooks fine with the local scheduler. The job does not show up on deadline. DEADLINE_PATH is set to the deadline installation folder and deadlinecommand is in the path and runs fine.
Any ideas on how to troubleshoot this?

I'm not sure how to remove just one. But yeah as a hack you can rebuild the dict without the keys you don't want.

Daniel_aRchI just built the correct env that I wanted from my venv during the launch of houdini instead of using houdini's houdini_setup_bash.
Have you ever resolved this issue?

I want to add a default python callback to all parm's on an hda that don't already have a callback set. Ideally I'd like to do this in OnCreated, but the only way I can see to add a callback is by modifying the parm templates in the asset definition. I'd rather not modify the asset definition.
If not, is there anything similar to Node's addEventCallback for parms?
I am open to even hacky ways of achieving this.
thanks!

I have a virtual environment and want Houdini to use that python instead of the one that ships with it.
My hope was that if I just sourced the virtualenv before sourcing houdini_setup_bash, it would pick it up.
The documentation says that I should point LD_PRELOAD to libpython2.7.so or include ‘/path/to/python/lib’ in LD_LIBRARY_PATH.
However, I can't find libpython2.7.so inside the virtual environment, and any ‘lib’ folder inside the venv that I add to LD_LIBRARY_PATH doesn't get picked up.
So my understanding now is that virtual environments don't come bundled with a full stand-alone installation of python (like Houdini does) and instead use the system's python libraries (even though they do come with a python binary executable).
How do I tell Houdini to use the python in the virtual environment?
thanks!

In the edit aliases and variables window you can define a custom expression function. What file are these saved in / what is the best way to manage these in a pipeline?
Is there anyway to export or define these from python?
thanks

I need to stop an rbd hinge constraint at a certain angle. Is there any built in way to do this? If not, is there a simple way to get the constraint's current angle? A simple to implement way would be awesome as I need to do this to tons of procedurally generated constraints.
thanks!
