This is a very simple script. (not really a maxscript, but useful for 3dsmax users)
It will allow you to use your backburner Manager to handle your Eyeon Fusion renders, using cmdjob.exe.
INSTALLATION
You have to copy the script on you fusion scripts comp folder (C:\Program Files\eyeon\Fusion 6.2\Scripts\Comp\).
Then you can access it at the Script top menu directly on fusion; you dont have to re-open Fusion for it to show.
