Screen Space Global Illumination Addon for Blender Eevee
Disclaimer: World/HDRI lighting in specular component is not handled properly between object reflections and gives inverted colors.
The addon (ab)uses Eevees built in screen space reflections with material nodes and thus won’t be comparable to a correctly built in SSGI solution.
