Updating Skeleton With New Bones

On the latest build, 4.12.

I added an extra bone to my skeleton to act as a simulated “jiggle” bone, however updating the skeleton by importing a mesh with the new bones seems to be very buggy. Several times I have lost all my work and had to re-import everything again, all animations and whatnot.

At any rate, whats the proper workflow for adding bones? Or is it just a bees nest and I need to try my hardest to design ahead and never add more “jiggle” bones?

Thanks guys!

EDIT: An example of a bug, is that sometimes adding a new bone would cause several bones to permanently ‘zero out’ their position to his feet for some reason, breaking animation.

Problem Fixed.

The issue was that the preview mesh didn’t have those bones weighted to any verts so they did not display correctly.

I know this was written a long time ago, but could you explain what you mean by this?

I might be having a very similar issue, what do you mean about bone weights on verts in preview mesh?
