Amplify Occlusion 2.0 sets out to deliver a new industry standard for fast, high-quality Screen Space Ambient Occlusion in Unity. This FREE UPDATE completely discontinues HBAO-based techniques in favor of the much superior Ground Truth Ambient Occlusion(GTAO), bringing quality and accuracy closer to traditional raytracing.
It’s a lightweight solution for consoles, mobile devices, desktops, and even VR, higher-quality and more accurate than standard SSAO techniques. When compared to other solutions, it offers superior performance scaling, even when combining high resolution and large sampling radius. When we said that you wouldn’t need to purchase another AO solution any time soon, we meant it.
Typical post-process occlusion techniques darken direct light the same way they darken everything else visible to the camera resulting in strong abnormal occlusion on bright lit surfaces. Amplify Occlusion provides an optional Deferred-path application mode that injects SSAO before the direct lighting stage in order to deliver natural and PBR-accurate results. Notice the direct lit stairs area and the sphere in the image below, in the Deferred image the the effect is exclusively applied to ambient lit surfaces.
