Well, I've been stumped! According to all the docs I've read when you apply an Upvector to a Bone Chain it always points at it in the Y axis. However, I'd like the Bone to bend in a different axis. Oh well, you might think, will have to work around it somehow - at the every least I can have an offset null or somesuch.
However, taking a look at some of our other rigs, someone managed to work out a way to change this axis. Now I've tried copying all the Joint parameters over but I can't find anything which gives it the same behaviour Any ideas what I'm missing? I've attached a couple of pictures to explain what I'm after.
