I've got the cyclorama, the infinity cove free set, the microcosm free set, the worldz set from 3dworldz, and I love them all. As stated above, they each have their good and bad points. I've discovered making my own "panels" for the cyclorama (much easier than I had thought) and infinity cove will take almost anything as a background. I haven't purchased the newer environment set from Sirius because I've been strapped for cash but it looks lovely. My motto: free is good! Download the daylights out of everything you can find and play with it. Then, purchase what is left and repeat as needed. Hey, Poser is an addiction...feed the need...now, how to get the lawn to spread like I want in the cyclorama.....hmm.....
