I use both Daz's Cyclorama and RDNA's Cyclodrop. I am another one who doesn't like the combination of photographic backgrounds with rendered figures - I prefer rendered backgrounds, but often don't have the time/can't be bothered/haven't the inspiration to make my own. I'd love to see some backdrops built along the lines of a stage set - I'm thinking of the sort of sets I remember from when my parents used to drag me to the ballet as a child. Not photorealistic, stylised, and dramatic!
