Just a heads up, I posted a Carrara file (and some rendered backdrops) into the free stuff.  It's the same scene I used to make the backdrop for my Blue Horizon image.

I had a request for the backdrop so I thought I'd sort of turn it into a nice freebie.

Please make sure that you read the description in the freebie because you will need plugins to make it work.  Also, I am using Carrara 8.1 utilizing the replicator.  If you have an older version of Carrara, I don't know if it will work.

Enjoy!
