I just found guy trying to repllicate last of us indirect shadows (which tomorrow children is also going to use) in ue4 , the early results were very good but sadly it seems that Arnage stoped implementing the tecnique altogether , I am pasting to demonstrate how inportant such a would be for ahr , another similar solution would be to imput the indirect lightning information as direct lights to the screen space directional oclusion that some people are requesting ( i dont know how different the two options would be , but has been itching my mind since long ago and if someone thinks the latter is not desirable or if the first is used some kind of ao would still be needed please explain why)
