OK, that’s one heck of a definition of Hemires ^.^!
Anyhow I think it’s like what I did, but that’s like an automatic process?
Don’t know ,just guessing.
Right, how did I fix it?
Well, all I did was subdivided the radiosity generating plane (emitter)
But I couldn’t differentiate between the two techniques to solve it. I did another render with increased Hemires and that took a bit longer to render, but the same amount of time it takes to render if I subdivided the radiosity generator plane.
Who knows maybe calculating a subdivided plane is faster than increased hemires for the CPU.
