While I have purchased P5, it does have a steep learning curve. I also have projects begun in P4 that are too near completion for me to be able to start over by learning P5 and then recreating things. Especially since those projects combine Poser with Vue (where I find it is much easier to build and light a scene than it is in Poser). So for me, while new projects will likely take as much advantage of P5 as possible (and perhaps even some elements will be useful for current projects) I am not about to abandon P4 just yet. Kate
