Ambient Occlusion Ambient Occlusion Settings Quality [ RESTART REQUIERED ] Quantity of samples used to render the ambient occlusion. The Very High setting can heavily impact your performance. [ 2, 4, 8 ] Resolution Resolution of the ambient occlusion rendering. Max Distance Maximum distance of the ambient occlusion rendering. Blur Base blur intensity to smooth the ambient occlusion result. General Radius Maximum distance to test the occlusion of a pixel. You may need to adjust the intensity of the effect if you increase the distance. Maximum Occlusion Maximum occlusion possible of a pixel. [ 0.0 = full black ] Global Intensity Intensity of the ambient occlusion globally. [ 1.0 = 100% ~ 0.5 = 50% ] HUD Intensity Intensity of HUD elements ( Weapons, arms, etc. ). This is a percentage of the Global intensity. [ 1.0 = 100% ~ 0.5 = 50% ] Flora Intensity Intensity of flora ( Grass, trees, etc. ). This is a percentage of the Global intensity. [ 1.0 = 100% ~ 0.5 = 50% ]
