There is a lot of disinformation about weight mapping in Poser.

First off, weight maps can only affect 2 axis's per rotation channel, that is how they work.

You do have a few options to affect the 3rd axis.

You can scrap traditional scaling and use that channel to do the third axis, but then scaling has to be set up as morphs with animated joint centers.

Or you can add another bone.

Or you can use a JCM.

Or magnets...

Why muscle rigging has never taken off sort of baffles me. Yes it is a harder to set up, so it isn't for everyone. If you want it to look like a person, it is far easier to pull it off in many poses when muscle rigging is used. Muscle rigging does present its own set of challenges thou, so it is not always the best type to use in every situation. But if you want it to look like a person, bend like a person actually does, you cant beat it...
