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.
This is a bugfix release, with minor improvements to animation import and export for Morrowind (thanks to arcimaestro for reporting these bugs!). See changelog for details.
You can grab the latest version of the scripts here:
