Setting the correct Pixel Aspect in Maya

I just recently ran into the issue of setting the pixelAspectRatio of the defaultResolution to a value that wasn't what maya was setting based on the width and height. I couldn't really find any answers on the net so I figure i'd put my answer up.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

import maya.cmds as cmds def setResolution(width=1920, height=1080, pixelAspect=1.0): ''' Sets render resolution properly. @param width- The width of the resolution. @param height- The width of the resolution. @param pixelAspect- The pixel aspect to set the defaultResolution to. Returns None ''' #Calculates the device aspect since pixel aspect isn't an actual attribute. device_aspect = float(width * pixelAspect)/float(height) #Set the Lock Device Aspect Ratio. IMPORTANT! #If you don't do this it won't work. cmds.setAttr("defaultResolution.lockDeviceAspectRatio", 1) #Set width, height, and aspect ratio. cmds.setAttr("defaultResolution.width", width) cmds.setAttr("defaultResolution.height", height) cmds.setAttr("defaultResolution.deviceAspectRatio", device_aspect) if __name__ == "__main__": setResolution(width=3168, height=2376, pixelAspect=2.0)

Hope this saves someone the time it took me to figure this out!
