About this mod

This addon imports & exports models between the latest version of Blender and Fallout 4, Skyrim, ad Skyrim SE directly, with no fiddling or cleanup.

Donations
This is a Blender export/import addon supporting Skyrim, Skyrim SE, and Fallout 4, and potentially FO3 and FONV if there's interest. 

Skeletons, bone weights, Skyrim partitions, Fallout segments, shaders, and extra data are all handled correctly. The tool also handles tri files, shape variants like Skyrim's _0 and _1 bodyweights, facebones mesh variants, and Bodyslide/Outfit Studio-style body morph tri files, some collisions, and various types of extra data. 

Shaders are imported to a Blender equivalent and exported back to the nif.

Works for Blender 2.91+, 3.0

Check the github for latest version and news. Updates here are spotty. The github is also the best place to report bugs.

Features
  • Supports FO4, FO76, Skyrim LE, Skyrim SE
  • Handles tris and base mesh in one step. No need to separate UV seams or triangulate before exporting
  • Handles expression and chargen tri files for Skyrim and FO4
  • Import tris into an existing mesh or on their own
  • Supports Bodyslide tri files on import and export for body morphs
  • Handles multiple bodyweights in one step. Export _0 and _1 armor weights for Skyrim from a single mesh.
  • Handles Skyrim partitions and also FO4 segments and subsegments (see the wiki for hot to get them right).
  • Handles skinned and unskinned meshes correctly. Exports head parts to SE correctly.
  • Handles shaders correctly. Set them up in Blender and export.
  • Handles some Skyrim collisions. More are coming.
  • Import-and-forget. What you import will behave correctly on export without fiddling.
  • Animation import.

What you don't get (yet)
  • MOPP collisions.

Status

Solid for what it does.

Installation

Get the latest release from  the GitHub release page. Install like any Blender addon. See the wiki for documentation.

What it is

Outfit Studio has working export/import for a bunch of the Bethesda games (FO3, FONV, LE, SE, FO4). I'm a modder and I've been using the niftools scripts for years, but I've started modding for Fallout 4 and there's no direct support for that at all. This spring I suddenly realized that since OS has code to do this, it couldn't be that hard to bolt their code onto a Blender addon, so that's what I did. The components are:

  • nifly layer: Does the heavy lifting. It's the part of OS/BS that reads and writes nifs and was recently separated out into its own library. All credit goes to Ousnius and the BS team for this part. Any bugs are probably mine.
  • DLL layer: Wraps nifly plus some additional OS code into a DLL that can be called from any program.
  • PyNifly layer: Provides classes and additional code to give a python-friendly interface to the DLL. Allows reading and writing nifs from any python code.
  • Blender addon: Provides an export/import addon for Blender.

Nifly can be found here. Bodyslide/Outfit studio is here.

Relationship to the niftools export/importer

This is an entirely separate code base and development stream, so the mix of features and limitations will be different. There's a lot of complexity handled by niftools that this exporter doesn't touch at all. 

Credits

The major effort here is in reading and writing nifs, and all credit for that goes to Ousnius and the Bodyslide team.
