Project Changer v0.8 by Unai - Lets you set up different projects without restarting max, use different map paths, etc. If you're interested in this utility, take a look also at Borislav Petrov's Project Manager script.
finalRender Script Utility v1.15 by Matthew Clementson - utility for adjusting finalRender settings on groups of materials or objects.
NRB Material ID Paint v1.0 by Antero Pedras - This script was made to turn the task of adding material ID to a mesh faster (and not so boring).
Anipose v2.0 by Chuggnut  - A small util for making the task of repeatable poses in animation much simpler. What it does is blend object positions and rotations and scales from the current frame to a stored pose. Think of it like morphing but only on whole object locations instead of single verts.
