Holofoil cards are great fun to pull in the Pokémon TCG, and with the stencil buffer and other Shader Graph tricks, we can create digital equivalents with a ton of tweakable settings.
By combining screen-space shadow maps, depth textures, post processing, and triplanar mapping, we can create flexible sketched shadows.
Turn any mesh into dazzling crystal by triangulating the mesh and using random vectors for lighting calculations.
Duplicating a mesh, inverting its faces, and moving them along the normal vector then drawing with a block color is probably the most widely-used outline method in games.
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.
