I am trying to use a very neat (though rather buggy) program called freestyle found here:
If you download the windows zip file you will find a prebuilt executable. Then you can generate viewmaps load python modules and create an artistic NPR render in seconds. It is very cool - try it!
The problem is that Freestyle isn’t importing the .3ds files that Blender exports. The .3ds files provided with Freestyle work as you would expect and Blender successfully imports these files but the exported meshes from Blender are incompatible (“radius is negative” error) even when everything is triangulated.
I would be very grateful if someone could help me out here. Unfortunately, I do realise that the “Other Software” forum isn’t exactly throbbing with activity. Anyway, I’ll try to keep my hopes up.
