What is an IWI file?
Graphics file used by the Infinity Ward game engine, which was used for some Call of Duty and James Bond first-person shooter games; stores textures for game models; used for overlaying graphics on NPCs, weapons, buildings, terrain, and other objects.
IWI textures can be converted to the .DDS format using IWI_X_DDS.
NOTE: The Infinity Ward engine was developed using the id Tech 3 "Doom 3 Engine" as a baseline. It adds several lighting effect enhancements.
