[Radiance-general] Re: Rendering with Radiance

[Greg Ward]

Hi Kam,

Sounds like a path problem -- make sure that your PATH variable is  
set with the executable directory for Radiance appearing before  
others in the list.  The "rview" name has been taken over by the  
"vim" editor, so use "rvu" instead.  I don't know of a conflict with  
genprism -- this you should try running on the command line to see if  
there is a problem with its arguments.

Best,
-Greg

P.S.  For future, please don't copy the digest in your e-mail.  Thanks.
