More Information

NIF files are also used to store "rigged" models, which contain default geometries that are used as templates for creating new customized models. NIF files can be compiled by the Gamebryo LightSpeed game development software.

NOTE: NIF stands for "NetImmerse File." It is named after NetImmerse, the predecessor to Gamebryo.
