NIF is a popular file format used by 3D games such as Morrowind, Oblivion, 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 release fixes a bug with skinning export: bone corrections would not be applied under certain conditions. From this release onwards, the developer documentation for the scripts (generated by epydoc from the docstrings in the source code) will be included as well.
You can grab the latest version of the scripts here:
