[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [12455] branches/qdune/blender: Added support for subsurf orco coords, but still doesn't work properly

[Alfredo de Greef]

Wait a minute, maybe you want to do it according to
the catmull-clark rules. In that case, qdune code is
not useful either, since only all other data except
the surfacepoints itself currently is as I said still
linear interpolated.
