[shailan zareiy]

Thank you Greg for your quick answer.
yes, the light shelf i simulate is a mirrored shelf.The material that i
assign to it is
void mirror Mirror3
0
0
3   .91 .91 .91
and the parameters of rendering are :
-dp=2048
-ar=32
-ms=0.063
-ds=.2
-dt=.05
-dc=.75
-dr=3
-sj=1
-st=.01
-ab=3
-aa=.1
-ad=512
-as=256
-av=0.01 0.01 0.01
-lr=12
-lw=.0005
I hope that these information is efficient
