In Beyond Skyrim projects, 3D artists are expected to be able to export their own meshes to nifs, 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 [[AU:Mesh_Export_to_NIF|export to nif]] from a 3D program or from a predefined format like fbx.

Nif files are much more than models. They also include properties and attributes which define how the model interacts with the game world physically. A detailed reference guide for nifs is available at the [[Arcane_University:NIF_Data_Format|NIF Data Format]] page. Here are some pages focusing in on specific aspects of nifs:

In Beyond Skyrim projects, 3D artists are expected to be able to export their own meshes to nifs, 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. For the basic process of asset implementation, see Intro to Asset Implementation

Skyrim Data Formats

Skyrim uses NIF and DDS file formats to store meshes and textures, respectively. That means your mesh must be converted to a NIF and textures to DDS.
