Just a post to let people know that I have posted a new free Carrara scene featuring a couple of octopus-type creatures and underwater style lighting. I was asked how I did this on a gallery so thought I'd share the whole thing.

Do what you like with it - render "as is", save the creatures for your own scenes, texture and bone them, or delete them and use the scene lighting for your own models and figures.  Enjoy!
