NIF is a popular file format used by 3D games such as Morrowind, Oblivion, Fallout 3, Civilization IV, and many more. The Blender NIF scripts enable you to read and write files that are compatible with these games in Blender.
Glow textures are now imported and exported for Fallout 3. Also for Fallout 3, the Emit Multi value can be set in the shader emit slider (up to a factor 10 to accomodate the range) and the emissive color is stored as Blender's diffuse color. For Morrowind, a new 'nif + xnif + xkf' export option has been added. Also, import of nifs that have multiple skeleton roots (such as the official skin meshes, and various creatures such as the ice raider) has been improved. Various bugs have been fixed as well: see changelog for details.
