Problems rendering krakatoa on my farm

The “Add Krakatoa to 3ds Max” utility adds an entry to the 3ds Max plugin.ini that controls which plugins are loaded. It looks something like:

Krakatoa=C:\Program Files (x86)\Thinkbox\Krakatoa\3dsMax2010\x64

Are you sure this is your problem? You should manually inspect the plugin.ini in the 3ds Max folder for the machines misbehaving.

You will definitely need to do this.
