Overview Exporter
The Overview/Radar texture exporter allows you to export an overview texture straight from your Max scene.
Export Multiple Texture Skins
You can give your model multiple skins (textures) so that the same mesh can look differently in different uses.
Generating LODs
The Level of Detail Generator on the Level of Detail Tools Rollout lets you generate LOD models from the root mesh. The tool will make lower-res versions of your model so that less polygons are rendered in-game when players move farther away.
Cordon Manager
The cordon manager lets you use multiple cordons and limit the compiling of your level to the area inside the cordon.

This page explains how to recover your displacements from a Sculpt Mesh that was never committed.
