The two won't conflict, Studio isn't as fully featured as Poser 5, being more on a par with Poser 4. Instead, they are developing plug-ins that will be sold. Personally, I prefer the Poser environment to work in, along with its materials and dynamics. On the other hand, a whole lot of people swear by Studio. I'm finding that 3D programs are not just about 'what's best' but 'what has the interface that suits you best'. Studio comes into its own for me in conjuction with Bryce, DAZ's landscape software. Studio makes short work of introducing Poser models to Bryce scenes and that earns it a place on my pc.
