By combining screen-space shadow maps, depth textures, post processing, and triplanar mapping, we can create flexible sketched shadows.

For a hand-drawn sketched loop, we can apply a special overlay texture in screen space which animates with a modulo clock.

For an easy sketched look, we can combine depth-, color-, and normal-based outlines with an overlaid sketch texture which animates in discrete time steps.

The Kuwahara filter removes noise from images, but it can also be used stylistically for an oil painting-like effect.
