To clarify...

In the render globals, under Render Options there is a check box titled Premultiply. When I'm working in Maya, I like to keep that box checked, but when I render on the farm I like to have it unchecked. This is why I want to automate the setting with my script that submits the render to the farm.

If I turn on echo all commands it shows the commands:

updateMayaSoftwarePremultiplyCtrl;
control -edit -enable true premultiplyThresholdCtrl;

but when I try and work these into a script nothing happens.

Thanks again.
