i've never used it or any other automation tool but i think acid has it right for learning rigging.
if you're flying solo because everyone around doesn't doesn't have a clue what a model is, then it's nice to have a model that is probably made perfectly so you can concentrate on rigging rather than rigging possible crap that you've made
i suppose being familiar with all these tools is a good thing though... i'll take your word for being able to recognise the automated stuff until i figure that out for myself :p
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
