I'm getting black lines & patches no matter what. :/
Code:
// +FN16 +BS5 +RP4 +RVP +am3 +a0.1 +r512 +ac0.999995 +w800 +h800
// Rendertime 12min 55sek
// Win 8.1Pro x64 on AMD PhenomII with 8 GB ram
#version unofficial patch 3.7;
#patch "upov-reflection-roughness" 0.9;
global_settings{ assumed_gamma 2.2 max_trace_level 36 }
#default{ finish{ ambient 0.1 diffuse 0.7 }}
camera {

}

}
}

texture {
pigment{ color rgb <1,0,0> }
finish { specular 1.0 roughness 0.0125 brilliance 2
reflection { 0.5 metallic 0.5 roughness 0.0125 } }
}
scale<1,1,1> rotate<0,0,0> translate<0,1.35,0>
} // end of sphere -----------------------------------
I would have liked to paste or attach an image here but...
I've tried to vary the +r, the +ac & the number of samples that the
focal blur uses, also the conf & vari, but no success.
The black patches only exist at the horizon while the lines/dots are
on the sphere.
Sincerely Rendering!
