v5 seems pretty sweet there are only a handful fireflies and i had the energy cranked up pretty high. I was pretty sloppy with the array of the spheres...

I let it bake for 1hour 30 minutes. I am sure it looked fine after 30 mins. 2200x2200
v5 is looking to be a real leap forward.
P.S. is there plans for Fesnel effect on glossy and spec materials? or am i just not seeing that octane already does it?
