Hi guys, I was looking at someone's tutorial (see link) and he mentions running a Perl script on a terrain to create waves. He supplies the script but doesn't mention how to use it. I've never run a perl script in Bryce before and I was wondering if anyone knew how to do it? I'd really appreciate any help.
