Arcane University:Blender Niftools Addon

The Blender Niftools Addon can be used to directly import and export nifs to and from Blender. It is created by the Niftools team, and hosted on Github. The most recent version can be found on the releases page. It is intended for direct conversion between game-ready nifs and Blender, including geometry, shaders, skinning and collision. At the moment, it only supports Skyrim LE nifs, and does not yet support MOPP collision (i.e. non-convex).
