and normals from blender using the python api.
The normals exporting provided too, because the python API
only gives access to the unconditionally averaged/smooth normals.
After patching, copy the 'weldmesh' folder from archive into '//blender/intern'.
The weldmesh is a free welding library, provided by Morten Mikkelsen. Much thanks to him!
Sample exporting script for writing tangents, normals and tangent's indices per face to file
is providing as "tangent_stace_test_export.py".
There also a sample blend file with simple model and generated normal map.
The patch is adding new python collections and classes.
For more info, look to 'readme.txt' file in archive.
