Just want to say that pixie is really a great too. I'm just preparing a renderman class and I use it for everything I need to show. I'll post the webpages here I prepared if anyone is interested.
I am always interested in renderman tutorials, so please do share the links here.
Here it comes. It is not complete yet, but I will continue to work on it. If you see errors or if you have suggestions or links for the links page, please do not hesitate to contact me.
