Unable to find IPRViewer in Houdini 18

[ninhenzo64]

Hi people,

I had some code which I was running to find the rendered image in the "Render View" pane and save it to file.

    _desktop = hou.ui.curDesktop()
    _ipr = _desktop.paneTabOfType(hou.paneTabType.IPRViewer)
    _ipr.saveFrame(_file)

This was running fine in Houdini 17. However, since updating to Houdini 18 (I'm using 18.0.440), the desktop object seems like it can't find the IPR pane, the paneTabOfType method is returning None.

Anyone have any ideas what I can do to get this working?

Thanks,

Henry

Your IPR being your output mantra_IPR? unless you are using another render engine?

[ninhenzo64]

yes, i'm using mantra renderer in the "Render View" tab - it's one of the default tabs when you launch a vanilla houdini

For those coming back to this, it looks like that way is deprecated. But you can do something similar like this

_desktops = hou.ui.currentPaneTabs()
_ipr = [x for x in _desktops if x.type()==hou.paneTabType.IPRViewer][0]
_ipr.saveFrame()
