Open and set some values on a Python Panel July 29, 2025, 10:20 a.m.

I have made a custom Python Panel, which lives inside a folder structure and loaded using a package.json file and the $HOUDINI_PYTHON_PANEL_PATH variable and a .pypanel file in xml format.
I am trying to make a button on an HDA that open a floating window and loads my panel, but I haven't had any luck so far.

The command below opens a PythonPanel, but I can't figure out how to change the selection on the drop down menu.
panel = hou.ui.curDesktop().createFloatingPaneTab(hou.paneTabType.PythonPanel, size800, 600))

Any idea of how to do that, or if there are any example code out there?

thank you

POP Wrangle Timestep Aug. 24, 2023, 11:08 p.m.

Hi,

I am building a Boids [www.red3d.com] system in a POPnet using POP wranges. I am trying to work out what's the correct way to apply forces and get the same results in different Time Scales, by setting the parameter on the POPnet.

In the simpler example attached, I have a few points with a popDrag and using a popWrange I set an upwards force just for one frame. If the particles cover 1 unit in 240 frame, I'd expect them to get there in 120 if I set the ScaleTime param on the POPnet, but they go twice as far.
I noticed the f@TimeInc attribute accessible on the POPwrange changes when I adjust the ScaleTime, so I played with the parameters. I got it somewhat close by turning off 'Use Timestep' on the POPWrange and setting the TimeScale param with this expression:
1/ch("../timescale").
It's not really there, so I wonder if it could get more accurate, or a better way to go about it.
Is there maybe an particle attribute that can be


Thank you

viewport keeps changing the camera April 9, 2019, 11:08 a.m.

Do you have lock camera toggle off? Although just going in and out of SOPs shouldn't deselect your cam even if the lock toggle is off.
I don't have this problem on my end.

Locking the camera prevents this from happening, but that's not a good solution as I may accidentally change the render camera position. I noticed when setting the triple option above the camera selection to view the rest of the scene, also prevents this issue.
I am in houdini Indie 17.0.459
Which version are using?
I will report it as a bug

thanks
