Frankly the new CS3 3d import is not really hugely useful to poser users as far as creating renders, you are far better off rendering your 3D object in poser and importing the render and compositing that, the reason being that the Poser renderer provides a lot more quality and features compared to the CS3 3D renderer, which is rudimentry at best(think OpenGL render). the CS3 3D features are primarily useful for photoshop users who don't have access to a decent quality 3D rendering solution. A texture artist may find the new features useful though, it doesnt take the place of a true 3d paint program becouse you can't actually paint right on the 3D model, but the benifit of being able to check a texture on the model instantly as you are working on the flat texture in photoshop seems useful, though I have heard from one user that photoshop has a tendancey to drop detail on export, I cannot confirm or deny this as I have not yet purchased a copy of CS3 Extended.
