I have Maya 6.5. Recently I had to re-install Maya because I lost Mental Ray. Well it's reinstalled OK and works fine. Now I go to place joints via the Joint tool and nothing happens either on the screen or Hypergraph. Is it because it's not registered properly and joint creation is not enabled? %$#@*&^% computers!
Have you tried placing joints in a view other than perspective (ie: front, top, side, etc)?
Good point, yes I have. I found out what the problem was, though I don't understand why. I was viewing the object through Camer1, a camera I created. I guess Maya won't create joints other than via the standard camera's.
