Ink'n'Paint with radiosity

[CrabPirate]

Maybe this question has been both asked and answered already, but I could not find any threads pertaining to it.

 

I've been tasked with creating a virtual map of a school campus and my employer originally was going to purchase a copy of Pencilsoft's Pencil+ shader for Max. (I had shown them several different render styles and they really liked the cell-shaded / hand drawn look). Well once my employer discovered all the hoops you had to jump through to purchase a pencil+ license they decided it was out of the question.

 

My solution was to simply use ink'n'paint materials combined with radiosity. (giving a smooth NPR look to the whole campus) I was especially enamored by the z-distance ink map. However, radiosity for whatever reason refuses to render the outlines of the objects that have the ink'n'paint material applied.

 

Is there a work around for this?

If you create a 3d shape you will get the outline render but if you create a 2d shape no outline will be created unless you put an extrude modifier on it or you enable the 2d shape in the render and the the viewport
