Hi… I just tried rendering a scene that rendered well on my previous computer (a Q9300) on my new computer (i7 2600).
the scene rendered well and fast, but I noticed some problems on the reflections. Basically, some black, aliased (as not anti-aliased) reflections.
After some tinkering, I noticed that adjusting the Exposure of the scene could increase or decrease the problem… at -0.27 exposure, the bad reflections disappeared completely.
Then I turned on Clamped Colors (which I have no idea what they are) and I noticed that at -0.27 there were no clamped colors… the entire screen was gray… but when I increase the exposure (at -0.27 its TOO dark), the SAME AREAS where the bad reflections appear, also appear when I turn the Clamped Colors layer/mask of the render window.
What the hell is going on after all
