H-Trace: Global Illumination and Occlusion
H-Trace is a screen-space horizon-based tracing algorithm that calculates global illumination and ambient occlusion in a single pass. Generally speaking, it's a modified GTAO approach that tries to solve GI in screen-space more efficiently than a regular SSGI ray-marcher does. The target pipeline (at the current moment) is HDRP.
