I started rendering a 280 frame animation last night. The animation used to take 12 hours to render in Poser 4. I added some displacement mapping to some of the objects in Poser 5 and started rendering using Fire Fly using shadows, displacement and texture filtering. Each frame was taking aprox 45 minutes and it died during the nigtht after 7 frames with a C execption error. I'm using a Pentium III 850 with 1/2 gig PC 133 mem and I'm running in Windows 2000 with the latest Service releases. I've also got the latest drivers for my Geforce GTS 64 meg video card. I'm using the last beta service release of Poser 5 as well. I may just not have enough machine for Poser 5 so I'm going back to Poser 4. I will miss the new bells and whistles but over 8 days for 280 frames is more than I'm willing to comit to my hobby. I will continue to try Poser 5 as the patches come out but this is a hobby and it's supposed to be fun. :)
