What is ZoneBuilder

ZoneBuilder is a tool built into IW4x that allows the creation of mods and fastfiles and dumping them to a human-readable format.

Usage

You can start ZoneBuilder using zonebuilder.exe shipped with the IW4x Rawfiles or by starting iw4x.exe with the -zonebuilder argument.

Working with IW5 assets

IW5xport can be used to export/convert IW5 (Call of Duty: Modern Warfare 3 (2011)) assets into a IW4x ZoneBuilder compatible format.

Porting CoD4 maps to IW4x

IW4x MPU has been created to simplify porting maps from Call of Duty 4 (Modern Warfare) to IW4x by providing an easy to use User Interface on top of iw3x-port and ZoneBuilder.

It's available for download on GitHub, with instructions provided in the README.
