When rendering terrains with multiple (not excessive) displacements, I am getting tiny white and blue spots that show only on the shaded of the terrain. I have the displacement tolerance set at 2, far as the slider will go, and Enviro Light at 2.5 strength on surfaces. This happened prior to my installing the "frontier" build - and after as well.
I've attached the .tgd. Maybe there's something in there causing it.
My machine is a 64 bit, 8 core (Toshiba Qosmio laptop) if that is of any benefit.
Thanks for looking into this.
