the level. The Reflection Ca pture acto r will rec eive indire ct and static lighting
from the scene and create a cubemap for the reflections to be projecte d onto
parts of the scene that receive re flection (i.e., parts of the scene that are within
the actor’s area of influence). We placed a Sphere Reflection Captu r e actor
close to the surface of the river and made its area of influence large enough to
affect the entire river.
Once the Reflection Cap ture actor was set up in the scene, we changed the
roughness of our water material to 0. This change makes the water material very
reflective. The material is already set up to be fully metallic, so the specularity
of our material is taken care of.
