There is no point in doing this unless you export the correct tangents and normals. That is the ones that were used to bake the normal map.
I realize it blows that there is no API function to get the render normal. So what you have to do is produce it yourself like is done in DerivedMesh.c<https://svn.blender.org/svnroot/bf-blender/trunk/blender/source/blender/blenkernel/intern/DerivedMesh.c> and many other places as well. An example in this file is the static function GetNormal() which is used as a call-back function by mikktspace.c and you can see how it uses the averaged normal if the face is set to smooth and it uses the face normal which it calculates itself if the face is set to flat. If you are going to make an api to export tangents I for one cannot emphasize enough that I prefer an all or nothing solution. Either do it right or don't do it at all. The last thing we need is to introduce a new tangent space standard within blender. Either export the correct basis that was used for baking (this includes the normal) or don't try to do it at all. _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
