How to add depth/thickness to Paper2D Sprites?

I’m trying to duplicate the depth “thickness” added to 2D sprites that 3dSen VR accomplishes (screenshot shown below)


To achieve this for Paper2D sprites, I’m assuming I’ll have to make modifications to the “DefaultLitSpriteMaterial” that Paper2D uses by default. I made a copy of the material, but I’m not sure where to go from here to achieve the effect (default material shown below).

Anybody know how to go about this?

That’s cool lol. It could involve POM (parallax occlusion mapping), though that wouldn’t be the entirety of it I bet. There’s also pixel depth offset, custom stencils, depth sampling, and world displacing.

UE5 has been released! Maybe there is a new approach to this problem (still unresolved)?
