[Radiance-general] Infor Radiance

[Greg Ward]

Also, make sure you render with -dr 1 or greater.  I think the default in rvu is -dr 0, which turns off virtual sources.

Cheers,

I'm using Radiance (with Ecotect software) for the frist time for my thesis and I've very short time to resolve my problem because I did, during last months, experimental texts but now I need to compare theese tests with the software in 3 weeks maximum . I'm studying different types of light shelves but when I do the simulations on Radiance I can't see the reflection of the rays (of the sun) on surface and on walls too. I'm using "mirror" like material of the light shelf. I tried all things that I could find on internet and on forum too, but nothing!  I'm really in trouble.  Please help me ! Thanks
