"I prefer arranging scenes in poser" No accounting for taste. The crude selection ability in Poser and the wonky orthogonal views to name but two problems make anything other than very simple scene setting a pain. And find me one other 3D program with no duplicate function. Yes, you can duplicate in Poser by saving an item to a library, creating a new instance, and then deleting the now redundant library entry, but what a cumbersome way to do things. I don't know that you can even do it with single lights. I suppose you would have to create a new light, copy the settings of an existing light and then paste them to the new light. Scene setting is much easier when you can lassoo a bunch of stuff with the mouse, click Ctrl-G to group it all, Ctrl-D to duplicate it, and rotate and drag the new group to its position. A couple of key presses and mouse movements only. "the bryce and vue way of rendering is very inefficient because it renders the same parts over and over again" The render pass system is not inefficient at all - since Vue is faster rendering than Poser, how could it be? And as I said, you get an instant look at how the render is going to be, without having to go through the motions of turning off all the shadows, etc.
