[Radiance-general] rtcontrib - rad3R9_linux

[Greg Ward]

Hi Germain,

The "too many modifiers" probably means that the mirrorfull_mat is  
being reused many times in your file.  You should define the material  
once somewhere and reuse it in our your included scene files.

As for the nothing output, this is of course suspicious, but without  
seeing your input files, quite impossible to diagnose.  Perhaps you  
could send those my way in an off-list e-mail and I'll take a look.

Best,
-Greg
