I learned something new about 3DSMax and Backburner today

Although 3DS Max 2009 can submit backburner render jobs to both 32bit and 64bit machines, it cannot submit to both at the same time. There is a toggle in the Advanced Tab of the network render dialog box see below:


This toggle allows you to send your job to either option but not both at the same time. You also don't want to mix and match render jobs on both 32bit and 64bit if you are creating an animation as you may introduce a noticable flicker in the final animation.

Thanks to Matthew Sulhoff at Incipio Technologies for providing the screen shot and some of the above information.
