There's the problem. Minumum setting of -1 would cause you to miss the fine
detail. That's what's causing the buzzing. Regardless of what you set the
threshold to, rays fired into pixels can miss the fine hair in some
instances. Use 2,2. Setting the minimum value to the same as the maximum
effectively turns off adaptive sampling and gives much better results on
detail. Threshold settings would then be irelevant. Same as the difference
between adaptive and Bartlet in SI3D rendering.
Personally, I find -1 a touch low, even for general purpose work. I usually
start at 1,2 oe 0,2 if I'm in a hurry.
Hope this helps,
