Ray Traced Distance Field Shadows enable you to generate high-quality soft shadow effects using 3D/volume textures, which store the nearest surface to a mesh. They can be used to great effect when dynamic lighting is required, and are generally 25% to 50% faster than standard depth-map-based dynamic shadows.
In this Unreal Tips & Tricks video, we’ll look at how to enable distance fields in a project, briefly discuss some ways to optimize them and go over the process of using them in a scene.
