I am not sure what prompted me to start doing this but it has been a great help to me so I thought I'd pass it on. In the course of creating an image in Poser, I generally end up with a dozen or more versions of the image saved on the hard disk as back up in case I screw up in making a change and want to go back. Well I came up with a better way that works kind of like an undo command. Since I am building a still image and not an animation, I use the extra frames for progressing versions of the image. For example, I have an image at frame 1, make it all key frames and contant, move to frame 2 and duplicate the key frames of frame 1. Now I can make changes, and re-key everthing to save those changes, and move on to frame 3 and do it again if I want to experiment with something else. At anytime, I can go back render any frame I want, or I can modify the image at a new frame with elements from the previous frames using the memorize/restore - element/figure/all commands. This way I only have to save the file I am working on, and possibly a back up copy. But I also have the freedom to experiment and copy changes from one version to the next within the same file. Hope this makes sense. If not ask, and I will try to do a better job explaining. Rob

I've been doing very much the same thing. Especially helpful to save different camera set-ups, poses and light positions. If I like something & think I'd use it on onother project I'll add it to one of the librarires. I still end up with a zillion "test" renders and dup files anyway.

Thanks for the warning Allie. So far I guess I have been lucky using this method, but I will take your warning to heart as I have not been using this method more than a couple of weeks and am not sure off all the pitfalls. I do remember all too well early attempts at animation and the unexpected changes brought on by spline interpolation - one of the reasons I learned to use the break spline key a lot. Rob
