Issue with Sequence Editor - Rotating Bones

<< < (2/2)

hf003:
Thanks much hihosilver,

That explains the issue very well. As johnar pointed out, it is exactly the Gimbal Lock" problem that I ran into here. I see most problems with "Gimbal Lock" can be avoided by choosing the correct axis hierarchy. I am assuming that can be done by rotating the bones in the Figure Editor first to get the correct hierarchy that best suits one's needs. I'll try what johnar suggested.
Thanks all

hf003:
After playing around with this a bit, I realized Gimbal Lock does not occur in the Figure editor. Both Sequence and Figure Editor allow bone rotation, yet Gimbal lock is only a problem in the Sequence editor. Although, I did not do an extensive test, I now believe it is impossible to avoid Gimbal Lock when animating all possible movements of a human's arms in the Sequence editor. If I am wrong, can someone please create a tutorial showing how to do such?

 

hihosilver:
You don't run into Gimbal lock in figure mode because you're not animating the bones.  You're simply moving them to where you want them to begin, so there is no issue.  There isn't necessarily a way to avoid Gimbal lock altogether, but there are definitely ways to get around it.  I don't have specific methods but I believe other members do (I believe they add an extra bone in the arm or shoulder.)
