[Radiance-general] sudo recontrib

[Andy McNeil]

Urtza,

You should open up permissions on those two files like so:

sudo chmod 664 GenericTranslucent20.dat
sudo chmod 664 rang.cal

This changes permissions to allow owner and group read/write and everyone
read.
(you need to be in the directory or give the full path to the file).
