This is a script the keeps track of "ExportSets" for UDK. It stores what object should be exported, and with what settings. It greatly speeds up the process of exporting to FBX for UDK, as you don't have to select anything and there's no export dialog anymore!
Right now it only supports Static Meshes and SkeletalMeshes, I might add animation in the future.
This is a macroscript that appears in the "FBX Export Sets" category. It should already have an icon if you place it on a toolbar.
