[Radiance-general] rvu: too many modifiers in ambient list

[Gregory J. Ward]

Hi Lars,

I had to check the code, myself.  Up to the limit (2047 in the  
current release), you can add modifiers to include or exclude,  
counting each once per appearance on the input.  (Actual instances  
containing materials count only once per, but repeating the same  
material name over and over does count.)  After the limit is reached,  
a warning is issued and further modifiers that should be on the list  
are silently ignored.  It still counts the ones up until that point.

As for Terry's question, your answer is correct about the #@mkillum  
lines on the input.  You cannot have different rtrace settings on a  
per-illum basis, however.  You can have different ones for mkillum  
than the rest of the process, by using a different setting for  
render= and mkillum= in the rad input file.

Hope this clears things up.
-Greg
