I've made a skeleton and placed custom constraints on the various limbs. When I go back to the constraints the limits are gone and the limbs move free. Happens when I save and come back. The limits go away somehow.

me too. i'm not sure if its a bug in the program or if i'm missing something obvious about custom joints, but i avoid them because they don't seem to stay defined. -scott

I think it is a bug, I try using it before the 1.1 patch and it definitely did not work then, but I haven't tried it after initialing the update. Maybe the bug was not addressed in the patch? I sure hope Carrara 2.0 addresses all this little quarks that are still hunting us.

My experience has been this...when I set it up it stays there...BUT it works like object collsion in the assembly room. If your hit the limit it stops...if you keep yanking on it it ignores the limit. I animated a robot once. I really like the feature b/c sometimes you want to go past the limit in certin moves (ie: sometimes whats correct and what looks right is not the same) but then you do have to reset. As for losing constraints after a save/reboot cycle..it never was a problem for me. Sometimes I have lost 1 constraint but never a whole skeleton of constraints..... -brent
