[Python/Api] Setting the active viewport

Coding
1

Hey All,

I’m working on a Playblasting tool, but am encountering an issue when running the playblast command itself,

What I’m doing:

Cloning the active viewport-

self.tempViewport = pm.modelPanel(tearOffCopy=self.activeView)

Setting the focus to the new script generated viewport

pm.setFocus(self.tempViewport)

Executing the playblast (Playblast command dosent let you name the viewport to Playblast from - it just takes the “active” view … which i assumed was the one with focus, apparently not! )

Any ideas on how to set the active view, via API or another method?

Cheers!

It is the ‘model editor’ inside the model panel that need to be activated, using the modelEditor command.

It is probably should be something like:

pm.modelEditor( self.tempViewport, e = True, activeView = True )

Sadly just been trying that again - Excuse Psuedocode

self.tempViewport = pm.modelPanel(tearOffCopy=self.activeView)
pm.evalDeferred(self.setFocus())

def setFocus(self):
      self.tempModelEditor = self.tempViewport.getModelEditor()

      print pm.modelEditor(self.tempModelEditor, query=True, activeView=True)
      [ This yeilds False ]

      pm.modelEditor(self.tempModelEditor, edit=True, activeView=True)

      print pm.modelEditor(self.tempModelEditor, query=True, activeView=True)
      [ This yeilds True ]

      pm.evalDeferred(self.createPlayBlast(),lowestPriority=True)

But Maya still gets the # RuntimeError: no active view for playblast # when running through… :frowning:

This code snippet seems to work for me. It appears that playblast() is intelligent enough to work on the active panel (not the model editor):


import maya.cmds as pm
 
 
print "Current panel to get playblasted is: " + pm.getPanel(withFocus=True)
 
tempPanel = pm.modelPanel(tearOff=True)
print "Tear off panel is: "+ tempPanel
 
print "Playblast currently focused on panel: "+ pm.playblast(activeEditor=True)
 
pm.setFocus(tempPanel)
 
print "Now playblast focused on panel: " +pm.playblast(activeEditor=True)
 
pm.evalDeferred("pm.playblast()")

Hey Phil!

It appears the difference to what ive tried and your sample is you’re doing

pm.evalDeferred(“pm.playblast()”)

I was evalDeferring the function that contained the PlayBlast command, rather than the playblast command itself.

After making a monster string containing all the flag arguments to pass into the PlayBlast command ive got it working as above as well :slight_smile:

Cheers!
