Maybe some guru could write a shader that negates part of the ‘AO’ effect back into the diffuse cause right now I’m guessing that’s where things end up a bit clunky. It all works, it’s all very realistic but that might just be it in the end. Sometimes a tad ‘unrealistic’ makes for a way better image. Not sure yet. I tried varies voxel settings and those all don’t matter much. All sliders under the ambient section are great for tweaking VXAO under just about any indoor/outdoor setting except for when working with dense foliage (why does it always have to be green stuff! :D). Somehow makes me feel tweaking 6x the same slider where I always end up with either too little AO or too much. For now I find it very tricky to get that sweet spot.
's some additional tests (last one being the control with VXAO off):
