Hi Esther, You have probably noticed that Carrara 5 has been announced and the good thing is that it has alot more poser support than Carrara 4 pro.Again I am not a poser user that much but you should look into what C5 can do . The good thing for you is that I think you bought C4pro after October 1 so you are eligable fot the free upgrade to C5pro that has the native poser import options.I would check this out if you haven't already. Also, before I told you that carrara didn't have something exactly like Vue infinites ecosystems , well C5 does(dont know what exactly ecosystems do though). You can create scenes with 30,000 trees etc and Carrara handles it with ease and the file sizes are small too.I posted an image in my gallery that uses the new clouds and the new surface replicator tool. You bought c4 at the right time I think.
