I'm tryiing to write a simple script to turn off the preMultiply feature in the Maya software renderer. I know I can just turn it off in the render globals, but I'm trying to set up a pipeline where it's on when working in Maya, but then when I want to render my sequences, my submit script turns it off and that way I never forget. The problem is, I've looked all through the docs, but I can't find a command to do this. There seems to be a command to edit every other setting in the render globals except preMultiply. Maybe they fixed this in Maya6, but I'm still in Maya5 for now.
If anyone knows this command, I'd be grateful.
