haven't had problems yet.. with the pz3 import... what's really cool .. is that instead of re-importing every time you change a pose... you can make a 10 frame keyed animation in poser.. once that's done...make every frame a different pose. save... import scene in shade.. then jump to any frame you want with in shade... oad a heavy pz3 with vicky 3,lots of props,etc...on my machine takes about 30 seconds... plus say an other 30 in poser to save the scene... i think it's worth it becuase the time you save with the advanced render engine more than make up for it in the long run... (that's ofcoarse if you import more than one posed frame at a time.)
