Back in the day, when calculating GI used to be highly CPU intensive, ambient occlusion was developed as its cheaper alternative. Ambient Occlusion, or AO for short, is an old rendering technique used as an approximation for true global illumination. It can be connected to other attributes.Hey VRay users, today I’ll be discussing how you can use the Ambient Occlusion map VRayDirt to enhance your images. yiAmbientOcclusionShader : It's a basic ambient occlusion shader.yiAODiffuseShader : It's an ambient occlusion plus diffuse.Receive Transparency : When turned on, the transparency is calculated. keep in mind, this mode might take some time.The ray is shot it becomes a square of the sampling value. Set 1 or more Reflections in Raytracing Quality when useing "add transparency".You'll find the "yiAODiffuseShader", "yiAmbientOcclusionSader" under Surface, and you can also find the "yiAmbientOcclusion" under General Utilities.Load the "yiAmbientOcclusion.mll" from plug-ins manager.Put "scripts/AE*.mel" into scripts folder.Put "icons/render_*.xpm" and "icons/render_*.png" into pref/icons folder.Put "plug-ins//yiAmbientOcclusion.bundle" and "plug-ins//key.lic" into plug-ins folder.This shader is an ambient occlusion for maya software render.
