Do you find the interface slow? No no slower than poser4 with PP. Do you find the program taking a pretty long time to load? About the same speed as 4, maybe a little slower. Do you find the rendering in Firefly sometimes cutting the head off Victoria, Mike, and even that funky looking Judy? No, not at all. Do you get those c exception errors? I did, but I removed the nipple bump maps from figures that had nipples and had bump maps applied there, the figures loaded and firefly works error free and the material room. Do you find the FF rendering a bit too time intensive ??? If I load up many polyed figues with huge texture maps and many lights, and do close ups with all the goodies checked. yes it is slow then again poser 4 was slow with like render. do you get render lockups? Not since I pulled the nipple bumps. In truth I prefer doing the firfly renders, they seem better and faster Does your library take a nap while it loads different subdirectories? Since I have my folders setup as figures/males/vendor going deep into my library does take a few extra second to load the thumbs
