Ive yet to find anyone else experiencing this problem, If i add a power fractal to a child layer of a surface shader and use that fractal for adding bump to the terrain if i go any lower than .01 in the scale the whole terrain starts to go darker the lower i go from there, this happens both in the preview window and when i render, any thoughts on this ? im trying to get some really nice fine/very small bumps on my surfaces to accentuate that the terrain is large and the details very tiny.
