Trying the non-raytraced SSGI in latest 2020 beta it seems more like a cheap AO in that it makes some areas darker, there is no ‘illumination’ as you would expect. Is this an early WIP?
Also, perhaps not supported in forward, but it can be enabled still and just looks odd.
The SSGI is working for you? I have been trying everything but it is not working for me.
Trying with Gradient Sky set to Black with all sides and using spotlight in dark-room.
SSGI have no any effect if I turn it on/off :\
Actually it is very hard to use and confusing. Not in play mode it seems to work one way and when you actually play it seems to work differently. Like concave corners were dark when I was in scene view, play the scene and corners were brighter than scene! I don’t get it & have abandoned for now! Maybe after beta they will at least show some screenshots of what it does on & off
I also still don’t understand how to use it, in theory, it should work like SSR, but it never works.
It does work. I’ve played with it many times 
You guys probably have HDRP settings wrong.
works as expected on 2020.2 b6
has some small lag tho… But I think that’s a drawback of SSGI itself
