Questions tagged [ambient-occlusion]
Ambient Occlusion (AO) is a method for making scenes more realistic by taking into account the shadows created by ambient light. The EEVEE render engine treats AO as a separate property and the material shader system has an AO node for managing AO. Use this tag for any questions related either to EEVEE AO or to the AO Node.
