I am having problems with bones that flip when I move the IK target very close to 0 degree mark (or 90 or 180 degrees… I’m not sure what the reference is).
I’m animating a swimming whale shark - with it’s tail swaying from side to side. Here’s a preview:
All works fine - up to close to the “zero” point of the tail, when the following happens:
As I get close to the “zero” point, the tail’s orientation is:
On (and in close proximity of) the “zero” point of tail, it suddenly flips straight:
…and just after the “zero” point, it flips in the opposite direction:
I want the tail to move in a flowing motion in the one direction (and do the opposite in the opposite direction), as indicated in the diagram:
It should not go straight at the zero and then suddenly flip immediately afterwards.
I think that it has something to do with where the “zero” is, because I have similarly NOT had the same type of problem if the “zero” was defined elsewhere, but I cannot seem to put my finger on it.
(I’m sure that I am asking a question that has already been answered, but I did a search on the forum and looked at Wavez’s BSoD document - and could not find anything in there either.)
Can somebody help?
