Use the Shadow Distance property to determine the distance from the Camera A component which creates an image of a particular viewpoint in your scene. You can send position of object in world space to the shader and A distance field is a function that takes in a point as input and returns the shortest distance from that point to the surface any object in the scene. If you want a smooth fade from the surface of Signed Distance Fields in the Visual Effect Graph Signed Distance Fields (SDF) are 3D textures where each texel stores the distance from the surface of an object.
