Well, there is the Interposer plug in for Cinema4D (that's 3rd party) which a lot of people seem to use. Poser content runs natively in Carrara, that's more of a middle end app, I guess. Have to break away from Poser for a little while and spend more time with Carrara...pretty darned disorienting, though. Being that Carrara is a Daz app I imagine that Genesis will get comfy there in it's next version?

...With Max who needs Vicky or Genesis when you can have all of those super sexy Turbosquid models. If you've got the income, that is.
