Illustration 3D scene setup

I've setup the last bits and pieces for the 3D illustration and we can now move into actually developing the look and feel of the final image using then NPR filters.

I've added a few sculpted details to the meshes but nothing to 'polished'. What I like about this 3D illustration workflow with NPR filters, is that a lot of the details and texture is given by the actual filter passes at render time and not necessarily from the sculpted details.

As you can see the sculpting work is really basic... just a few concrete alphas for the wall and polished with the trim dynamic. The polypaint pass is also pretty simple but here's the trick...
