OSX rpict errors with mkillum

Greetings,

I've finally made the plunge from running Radiance in Linux on a PC to OSX, never thought I'd see the day! I compiled Radiance using the OSX binaries and all seemed well until using the "rad" program with an illum source in the "rif" file. Once mkillum finishes and rpict kicks in I get the following rpict error:

rpict: fatal - cannot find data file "illum12.dat"

The odd thing is that the illum12.dat file was created and is in the directory.
Thanks ahead for any insight / advice.

Hi Chris,

This sounds like a RAYPATH issue. What do you get when you type "echo $RAYPATH"? I'm guessing you don't have '.' in the path for some reason. Either that, or the directory you're in doesn't have the right permissions. (Though I would expect an earlier error in that case.) What do you get when you type "ls -l illum12.dat"?

Hi Greg,

Thanks for your quick response. Yes, in my conversion to OSX I'd forgotten that I was now working with bash and hence had a space in the path statement where it should not have been. Back to basics 101. Thanks again.

Best regards,
Chris
