Select primitives with python in Scene Graph Tree in Solaris June 6, 2025, 5:56 a.m.

Hi guys,
I am trying to use Python to select primitives in the Scene Graph Tree, but I am not successful.
According to the documentation here
https://www.sidefx.com/docs/houdini/hom/hou/LopNetwork.html [www.sidefx.com]
it looks like it should work.
However, for me, it is just selecting the root primitive and not the one specified.
I've tried two different methods, one based on the network and the other based on the viewer, but both work the same.
Can anyone help me with that, please?import hou #Get current network viewer = hou.ui.paneTabOfType(hou.paneTabType.SceneViewer) network = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor).pwd() #OPTION 1 viewer.setCurrentSceneGraphSelection("/pig/geo") #OPTION 2 network.setSelection("/pig/geo")
Ok, I figured it out. For anyone who will find it useful.
The function expects a list. So it needs to be like this
viewer.setCurrentSceneGraphSelection(["/pig/geo"])

You also need to apply the changes to the current viewport.network = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor).pwd() load_masks = network.viewportLoadMasks() load_masks.setPopulateAll(False) network.setViewportLoadMasks(load_masks)
Interesting, awesome! That works great. Thanks a lot, alexwheezy, for your help!
