Hi Martin,

I used to dabble in Linux for a while, but then made a rule for myself, if it doesn't work out of the box forget it, I can do more interesting and productive stuff with my time instead of trying to work out how to get something running on an un-native platform when it already runs perfectly on another, that's just me.

Anyhow here's a free renderer that runs on Linux, http://www.luxrender.net/en_GB/standalone

Cheers
