In Beyond Skyrim projects, 3D artists are expected to be able to export their own meshes to nifs, and textures to DDS, if they are simple enough. However, for more complex objects, like animated objects, or those with particle effects, it may fall on an implementer to bring this into Skyrim. Other partner projects of the AU may have the entire responsibility of bringing a mesh from fbx to in-game fall to the implementation team. Therefore, the first thing you should know is how to export to nif from a 3D program or from a predefined format like fbx.
