UltraThe highest quality AO. It takes quite a long time to calculate but produces very good results. This is the recommended quality when baking Lighting for high resolution assets with small details. HighHigher quality AO that is slower to calculate. It is useful when you have small, intricate shapes. MediumThe default value. A good balance between quality and speed. LowLow quality Ambient Occlusion. This is quite sufficient in many situations.
