.assExporter is the
plug-in for 3ds Max that exports the world data (e.g., vertices,
materials, world geometry) from 3ds Max to a file format (.ass)
that Halo 2 Tool and Map Editor
Launcher can understand.
The .ass file format is an intermediate version
of a Halo 2 map on its way from a modeling program (3ds Max)
to the Halo 2 for Windows Vista game engine. Data stored in
.ass files must be compiled by Halo 2 Tool before the Halo
2 for Windows Vista engine can use the information.
For more detail about .ass Exporter, see the
Using .ass Exporter
section. For a complete file specification for the .ass file
format, see the .ass File
Specifications section.
