Hi Dan, You must have missed the bit where I pointed out this error and where I fixed it.
That was a silly mistake I made because I was talking at the same time as doing stuff…which
But the easiest way to fix it would be to unparent any geo that is already parented to any of these bones (except if you used bone relative parenting)
Then select each bone and change the x value of the head and tail to 0
(or position the cursor anywhere at x = 0 and then scale the bones to the cursor but constrain it to the x axis)
Then reparent.
But you are correct, it is an excellent learning opportunity.
I can’t say that you or I won’t make that mistake again, but now you know how to move bones around after they have been parented.
