The thing about all these programs is they are unique and when you are used to another program is can actually often create more of a learning curve. I don't think there will be a workflow that will be just import and render in carrara. The options in carrara maybe frustrating at the moment, but once you start learning all the things you can do with them I think you will love it. I don't use poser never have so I didn't have to adjust to anything else. I am far from having all the lighting down. I am always trying different options.

No need to think outside the box....
    Just make it invisible.
