The Cove backgrounds can also be used on all of the Infinity Coves including Render Studio for Poser and Render Studio for Poser 8.
Remember you don't have to use the same images on both the Cove and the Sphere. You will get some really interesting results using different images.
There are a few suggestions from our testers in the readme.
Our Special thanks go to Suze who created the renders for us using Kali, Harpert (a clown variation on Mr. Pitterbill), and Cookie.
