I'm currently using Maya 5.0 and I'm doing some work with Mental Ray. I've noticed that when you do a batch render, the little box that appears beside the menu with the Maya Software Renderer is gone, so you don't have the option of ticking, "use all available processors" in Mental Ray.
Is this because Mental Ray automatically uses all processors, or can it only use one? I have a dual processor machine at home, and it would help if I could use both while rendering.
If anyone has any info on this, I'd like to hear it.
