I think BeamNG should consider trying to implement Nvidia's VXAO as an option to replace the SSAO, which imo looks really unrealistic in most situations. The current SSAO doesn't look very good especially with a low radius, as it kind of just creates a ring of shading around the bottom of the cars. It's very noticeable on cars like the Scintilla. It does look slightly better with a higher radius, but that causes a lot of weird effects and sometimes the shading still doesn't cover the whole car. VXAO fixes this by using world space data which should mean that there will no longer be rings of shading, but rather realistic shading under the whole vehicle, shown in Nvidia's tank render. VXAO is probably the closest thing to ray tracing and if it's possible to add to BeamNG, I think it would give it a LOT more visual realism, since BeamNG doesn't even have any sort of dark shadows under cars.
