For Ray tracing, disabling ray-traced shadows on the light, setting the console variable to 0, or changing the fallback relative error can improve the quality of shadows.  I had a project in 5.  As this picture tries to show, moving a slight distance forward towards this mesh results in a much more dark and detailed shadow appearing under the bricks. gg/38ceaJ67Eu0:00 Int Here&#x27;s what we need to do: pick a point or spot light.
