Nemyax, the thing you propose sounds as too perplexing for someone who is a simple user, knowing almost nothing about technical issues. : - )
Isn't Freestyle in Blender a v2.67 target? i.e the next release?
Yes, it is a target for the next release of Blender... but I did explain the reasons that make me prefer having a very simple kind of such a renderer in Wings, in my second post in the present thread.
Apart from the reasons I did give there, there is the advantage of the easy access that may offer such a renderer to someone who uses as a modeller Wings, of course.
