Hi

I'm getting strange black reflections on shiny balls.I'm usingt mlpov 0.8 
with hdri. Anybody has an idea what is causing this?


The balls consits of two parts an inner ball with the following texture
#declare  lightyellowfinball =   finish { ambient 0 diffuse .0 reflection 
{ <2.3,2.3,1>*1.1*0.9,<0.5,0.5,0.5>*0.9  } }


around this is a second ball slightly thicker
with the following texture map

#declare ttextur=   texture { pigment {rgbt <1,1,1,1>} normal {bumps 1 scale 
.01}};
#if (strcmp(texturepic,"")!=0)
sphere{
0,1+0.001
      texture { uv_mapping
        image_pattern { gif texturepic  }
        texture_map {
                [0 uv_mapping ttextur]
                [1 uv_mapping textur scale 1/mapscale]
                }

         scale mapscale
         translate <0,1.02*mapscale,0>

        }
rotate <0,15,0>
translate <0,1,0>
}
this seems to work fine for the balls themselves, but the transparent part 
of the reflections go black... When i render the same pic without the second 
ball the reflections don't go black
