Nif
From GECK
<nif> is a user interface tile in Fallout. <3d> tag can be used as alias.
NIF tiles are used to render a NetImmerse Format 3D mesh to the screen; these are often used for 2D components that require animations or complex shapes. 3D meshes use similar coordinates to tiles in a menu, but with different axes. The contents of the specified NIF file are inserted almost directly into a tile's rendered content.
Note that the game engine deliberately limits the features that a NIF in a menu can use. NiMaterialProperty and NiAlphaProperty blocks will be stripped out of your 3D content when it is spliced into the user interface.
The exact relationship between 2D and 3D content is as follows:
| Direction | 3D axis and increment | 2D trait and increment |
|---|---|---|
| Right | X +1 | x + 1
|
| Down | Z -1 | y + 1
|
| Front (depth) | Y -0.008 | depth + 1
