Hey, sorry I didn't reply to you...geez its been over a year. By now you probably don't even care anymore. I just used C4d because it is very easy to get good rendering results very quickly. You can even set up your renders to only render the selected object, leaving the background transparent. Sorry I left DA.
I thought Cinema 4d was for animation? Did you export this into as a jpg or pdf?
than finished it in photoshop?
