Albedo Confusion
Question: I have a ground plane that is reflecting indirect light from Realtime GI way too brightly and making the undersides of my foliage have a neon green glow. I attempted to lower the 'albedo color' of my ground material in the materials tab from base white to a medium grey and that fixed the glow, but now my ground is puke green colored. Trying to fix it using Post Processing Stack only resulted in washing out my scene to the point that it looked better before the Realtime GI. How can I remedy this glowing without making my grass incredibly dark green?
(The left plant is dynamic, and the right plant is static and has the unwanted illumination)

You can change the intensity of indirect lighting on an object using an occlusion map (or a surface shader that writes to the occlusion channel).
From what I read in the link it sounds like I'd be stopping the indirect light received by an object (the plant) ins$$anonymous$$d of reducing the light transmitted by the ground. That would mean getting occlusion maps for all of my vegetation objects and given some of them are store assets I don't know how I would go about doing that. Is there really no way to reduce the amount of indirect light that reflects from the ground?
I don't think there is but I might be wrong. What you can do is reduce the "Indirect Intensity" in the lighting settings but that would affect the whole scene.
