Question Is it possible to make a sprite cast a shadow that is the shape of the opaque parts of the sprite?

    I'm making an HD-2D game, kind of like Octopath Traveller, Triangle Strategy, or the new Live A Live remake. My effects look almost perfect, but when I turned on shadow casting for the SpriteRenderer the shadow was just a square. Is there any way to make the shadow the shape of the opaque parts of the sprite?

    Yup; alpha clipping does this. If you're using default URP lit material, just check this box (and adjust the cutoff as needed):

    If you're using shader graph, it's here:

    If you're writing your own shader, use clip() inside the ShadowCaster pass.
