Non-photographic Render

It is not obvious in middle of galleries using cycles to find NPR artwork.

But I found this one.

Freestyle is the part of renderer in charge of stylized lines.
And it was used until now, mainly with Blender Render engine.

In 2.8, it will still be available. But Blender Render will not be present.
So, shaders will have to be done using Cycles or EEVEE.

And another NPR renderer for lines called LANPR is in development.

But blender 2.80 (first stable release of 2.8x series) will not be officially released before next year.
