NeverBlender
From NWNWiki
NeverBlender is a set of utilities for Blender 3D modeling and rendering package. Currently, the most prominent tools in the package are nwnmdlexport, which will export Blender-created objects to NWN ASCII .mdl format, and nwnmdlimport, which will import .mdl geometries and associated textures into Blender.
The featureset is fairly complete and it's easily extensible. The only major features missing are animation exporting and particle effects.
Currently, there are no actual releases, but the code is available through CVS and there are snapshots available.
