This mod tweaks the engine settings through the Engine.ini file for better ambient occlusion. Adds better ambient occlusion through either Ray Traced Ambient Occlusion (RTAO) or GTAO (Ground Truth Ambient Occlusion). RTAO will obviously look better, but run worse.
IMPORTANT: RTAO is expensive, and is only excpected to run smoothly on mid/high-end 30 or 40 series NVIDIA cards. Recomended to use GTAO.
RTAO runs mostly @ locked 4k 120fps on a RTX 4090.
Comparisions Vanilla vs RTAO (imgsli):
Iwatodai Dorm 1 Comparison (Ultrawide)
Iwatodai Dorm 2 Comparision
Iwatodai Dorm 3 Comparison
Paulownia Mall Comparison
How to install (Steam):
BONUS: If you are using RTAO and struggling with performance, try decreasing r.RayTracing.AmbientOcclusion.SamplesPerPixel. Increasing it makes AO resolve more detailed. Must be a multiple of 2.
Also, feel free to add other Engine.ini settings.
KNOWN ISSUES:
GTAO provides overall better AO than vanilla, but might darken the overall scene depending on where you are.
Although RTAO is vastly superior, RTAO unfortunately causes a few visual artefacts, mainly with glass objects. This happens because RT transparency is not supported. This causes the glass on the bookcases in Iwatodai to not be transparent. Same with the bulletin-board on Paulownia mall. Also, the crane game in Paulownia has broken occlusion inside the glass. Another minor artefact is that sometimes character faces receive very slight blocky shadows. Can be seen in all-out attacks, but I have not seen it elsewhere. There is no fix for these as of now. Any bug post about this will be removed.
