# fast easy work around for rendering hardware2/viewport2.0 sequence frames in Maya 2016
# you still need to setup for animation in the 'Render Settings'
# Change 'Frame/Animation ext:' pull down, so that each frame will be written out
# with name frame padding, etc.

import maya.cmds as cmds

startFrame = int(cmds.playbackOptions(q=True, min=True))
endFrame = int(cmds.playbackOptions(q=True, max=True))
