SSRT 3 (for Screen Space Ray Tracing) aims to emulate path tracing and produce indirect illumination from screen pixels instead of scene geometry. It's very similar to Unity's SSGI, but much less noisy because it uses a horizon-based sampling method instead of …

Jul 11, 2019 · GI Boost: Intensity of the indirect diffuse light. Light Buffer HDR: Using an HDR light buffer gives more accurate lighting but have an impact on performances. Light Buffer Resolution: Using lower resolution light buffer can help performances but can accentuate aliasing.

Feb 16, 2023 · Basically a very limited screen space ray tracing global illumination. It's a global occlusion and illumination but doesnt compute what's outside the screen. For this reason, it's difficult to tweak and use properly.

Oct 20, 2022 · Real-time global illumination using screen-space information for HDRP. Like our previous implementations (SSRT) the algorithm is based on GTAO and uses a horizon-based method to retrieve GI samples, which makes it a lot less noisy/blurry than HDRP’s SSGI. Performance is also better than SSGI, at around 2-3 ms on an RTX 3060 for the entire effect.

This is an open source screen space ray tracing shader for reshade - jebbyk/SSRT-for-reshade

Aug 23, 2020 · Blender user “0451” just released a free SSGI addon for EEVEE on his Gumroad page. His addon cleverly combines all the scene’s materials with Screen Space reflections, allowing for this screen space GI effect. This gives it the benefit of working “realtime” straight from the viewport, on top of EEVEE’s traditional baked GI which uses probes.

Oct 27, 2020 · Does anyone knows if there’s any plan of implementing SSRTGI instead? Epic team or as a external plugin. How difficult would be to code and impement this?
