Screen Space Ambient Occlusion (SSAO)
We improved the quality of SSAO (screen space ambient occlusion) when rendering to provide significantly better quality with less artifacts and more possiblities to adjust the appearance.
Find our realtime Screen Space Ambient Occlusion in Visualization > Rasterization Settings > Realtime Environment Shadows
