The Poser manual does not say anything about correcting errors when bending body parts. Does anybody know how to avoid this problem? Thanks

Bad case of poser elbow. Either don't bend it that far, hide it behind something or do a lot of post work. Sorry, no real helpm, but I feel your pain. :(

That really cannot be avoided in many instances. Your best bet is to fix it in post work. It's really not that difficult, nor does it take a lot of time. You just need the right tools. What's you graphics app?

You can use ctrl z to correct one move at a time. I use the dials to pose so that I can make my moves in increments. If you do post work you can fix it there, but if you are animating you will need to learn to use smaller movements and more than one dial. 8^) Marque

As Marque says, use more than one dial, and check to see if "use limits" is checked in your menu. That will restrict most body parts to their natural range of motion (or at least what Poser can handle). Carolly
