hello all, need help with this style of rendering

hello all,

i am having trouble figuring out the exact method to replicate a pure black & white style of rendering like the image in the link below

http://media.cargocollective.com/1/...aderimg/AAA.jpg

i am using vray with rhino or maya, and if anyone can share their thoughts on how to achieve that kind of effect with vray, please let me know. thanks!

Looks like a simple cartoon shader with lines on top to me.

Yeah that's definitely a toon shader of some kind. Something like this:

It looks like self illuminated shaders, black and white.
And an overlaid shadow pass, 100% black.
I suspect the result it's not really a lot 3d, but photoshop tricks. There is this black area where the toon lines are inverted to white. I think it's just inverted with vector masks. Maybe the shadow pass used as mask. Maybe many black areas are just made with the photoshop fill tool.

I might be wrong, but to me that drawing seems to be a section cut generated directly from Revit, it's a vectorial drawing.

But if you need to get that kind of effect with a renderer, I would turn off Global Illumination and generate a shadow pass( sorry I don't use vray so don't know the exact name for the render pass). Then, in photoshop make a selection based on that shadow pass and fill it with black.

To get the outlines use just a toon shader on vray, as leigh pointed out, activating just the contour lines. And compose the outline render on top of the shadow pass.

You mention you use Rhino, I think it might be easy to get this effect generating a 2d vector drawing from your 3d in rhino and exporting that drawing to Illustrator or a similar vector drawing soft.
