We made UI for the great 3dsmax script : "RTT Assist"
RTTassist is a free MaxScript toolset shaped in a beautiful interface that automates the tedious process of texture baking.
It has a wide range of features, but most especially it is designed to give you better user experience!
Take a look at some of the main features at: http://vertexbee.com/rttassist.htm
