Stylized Shadows

[pemattern]

I have searched and chatted in an attempt to find an answer. How do I create stylized shadows in bevy? Specifically, I want to create a dithering effect on shadows. It seems there isnt something like a "Screen Space Shadow Texture" or something. I know how to create a dithering shader I just dont know how I can manipulate the shadows in bevy with one.

Any ideas?

Thank you!
