HTrace: Ambient Occlusion HDRP v1.4.0 (07 Apr 2026)|HTrace: Ambient Occlusion HDRP v1.4.0 (07 Apr 2026)

 HTrace Ambient Occlusion combines three of the most popular ambient occlusion techniques into a single asset, offering a highly scalable and adaptive system for AO computation. Includes three AO modes: ▪ SSAO (Screen-Space Ambient Occlusion) – A lightweight and extremely fast method for occlusion gathering. It doesn’t require a denoiser and produces zero temporal lag. ▪ GTAO (Ground-Truth Ambient Occlusion) – Built on the latest advancements in ambient occlusion research, this technique works seamlessly with or without a denoiser, delivering the best possible quality in screen-space. ▪ RTAO (Ray-Traced Ambient Occlusion) – The most accurate occlusion method, utilizing hardware ray tracing for uncompromised quality and scalable performance.
