Every now and then we do get asked if BackBurner does cross platform rendering. The simply answer is yes but there is indeed some setup involved to make sure things work.
In this video I explain two key components to get this up and running. The first is setting the correct path to Maya's render command so both Windows and Mac OS can use the same command when submitting the job. The second task here is to mount a samba drive on Mac OS. In the video I show a simple method of gettng this done but you will loose the mount at reboot. To keep the mount through reboot I suggest you lookingto launchctl command and how to use it.
Hope this helps!
