Some test renders I did using the PixelArt.osl, by Zap Andersson. It feels kind of naughty using an unbiased, photo-realistic, physically-based ray tracing engine to do this kind of thing, but a lot of fun nonetheless 🙂 Rhino and croc models from Zoo Tools.

Download the shader here. Connect it to the toon.base_tonemap and render with Camera (AA) samples -2, closest_filter.
