Grook: Turn the BUMP maps off or take them out of each figure. This is an old problem with Poser dateing back to poser3. For some reason the rendering of bump maps totally screwes up the animation and causes the computer to lock up. I have rendered 900 frame animation with no problem. As long as the bump map option is turned off. If left on I get about 150frames then crash. The other option is to render to frames, this way when it locks up you just start the render from the last frame. BUt there are problems with this as well. only being able to render 255 frames at a time before crashing. Good luck Karl
