It really depends on what style you want to achieve but it can get quite hairy pretty fast. Non-photorealistic rendering is actually a whole (fascinating) academic field in itself. Since you have conflicting goals (temporal coherence, spatial coherence, "flatness", relatively constant stroke/feature size, ...) it's full of interesting tradeoffs and techniques. Even simple things like beautiful real-time stylized outlining can be really hard if you are picky about the result.

For anime style you'll need a little more than just a few shaders. The models themselves need to be distortable and perspective-dependent.

  I know very little about this field - why would a model need to be distorted to give an anime look? (Also, what does perspective-dependent mean in this context?)

    Re: perspective-dependence: I'm assuming they meant that in actually hand-drawn anime, things like hairstyles or eyes are not realistic because they switch shapes and locations depending on the perspective (like, both eyes always visible even when almost-sideways, or hair spikes switching from left to right when the character turns, etc).

      Good, and incredible impressive, examples are recent entries into the Guilty Gear series, such as Guilty Gear Xrd: Revelator: https://www.youtube.com/watch?v=tY1RpK1vbTo https://www.youtube.com/watch?v=tY1RpK1vbTo https://www.youtube.com/watch?v=5z5-97rfHEg https://www.youtube.com/watch?v=5z5-97rfHEg https://www.youtube.com/watch?v=tHp3fmDypg0 https://www.youtube.com/watch?v=tHp3fmDypg0 One early example in the first video is the shell casing, which is replaced with a model that has some motion blur-like extensions.

        Here’s a short pdf breakdown of the shading tricks used in this game: https://www.dropbox.com/s/3ltkinwnmmzurjw/GuilltyGearXrd_shader.pdf?dl=0 https://www.dropbox.com/s/3ltkinwnmmzurjw/GuilltyGearXrd_sha...

      Thanks! For anyone interested, I found a paper on the topic (pdf): "View-dependent geometry" [Paul Rademacher, 1999] https://www.cs.princeton.edu/courses/archive/fall00/cs597b/papers/rademacher99.pdf https://www.cs.princeton.edu/courses/archive/fall00/cs597b/p...

That might be what Unreal Engine refers to it as, but in academia it's referred to as NPR Rendering - Non-Photo-Realistic Rendering. https://en.wikipedia.org/wiki/Non-photorealistic_rendering https://en.wikipedia.org/wiki/Non-photorealistic_rendering
