So, my situation is kind of unique. You don’t see many Unity users using the URP and even less using it with 2D.
Basically, I’m using the Cinemachine package as well to have some sweet gliding effects to follow my gameobject around. It’s set on a dolly track and is pointing at the game object (the the rotation is never going to be perfectly 0). However, when the 2D Shadow Caster from the URP package “casts” the shadow, the camera has to be perpendicular to the object that the shadow is on in order for it to be visible (I’m using a perspective camera for my unscrupulous purposes).
