i'd like to respond to pakled's response. a lot of times i will transport to poser to bryce via daz but it is really more for an exercise. u can use bryce as a backdrop for poser and use poser ground as a shadow catcher and get great work. most of the high paid professional 3d and mixed media digital painters use so much layering it's ridiculous but newbies insist on being pure and get everything done with one render in one app. also with poser u can backdrop animations and lay your poser animations on top of your bryce animations. if u really would like your final render to be in bryce you can get several complex images into bryce by exporting tiff and png images in poser and then make 2d picture objects and put them wherever you want into your bryce scenes; and they easily pass as 3d. if ur careful u can even get away with using these 2d picture objects in ur bryce animations without notice.
