hi Shamim
do you assign the mirror surfaces as secondary light source? if you use
ecotect for modelling, in the material assignment of this software, in the
advanced export you should write this discription :
void mirror materail name
0
0
3 1 1 1
does it solve the problem?

If all these surfaces are mirrors, then you cannot see anything.... unless:
- there is a non-mirror reflecting object somewhere in your scene that is
supoposed to be lit by the multiple-reflecting light path; since it will
reflect light in many directions you should see it!
or
- your point of view is located somewhere on the multiple-reflecting light
path and your view direction points towards it. Then you should directly
see the light source appearing as an image on the last mirror.Raphaël

Objet : Re: [Radiance-general] Light Shelf ReflectionsI am hoping to see multiple reflections of the light beam reflected off
the light shelf top surface in both the floor and the ceiling (all of which
are mirror surfaces).On Mon, Mar 11, 2013 at 10:40 AM, Jack de Valpine <[email protected] > <mailto:[email protected]>> wrote:

I am using Radiance via Ecotect. I have played around with changing the

Are you using the default parameters for rpict/rtrace? Have you tried
setting the -dr parameter greater than 2? If you post the command you are
using to calculate the reflections, it may be easier to comment. I suspect
it will be more complicated than the -dr setting, but that's a start.> I have been unsuccessful, so far, to generate more than two
reflections.________________________________________________________
