Houdini is very inspiring to me and seems like it will be a worthwhile suite of software to master, even if I can't personally afford it. However, I can only find tutorials on rigging an arm and a foot. I'm sure there are snares to avoid with other parts of the anatomy, so I am hoping to find a complete set of lessons on character rigging and eventually on total character animation with Houdini. It may be too early to ask for such things, (seeing that it's character animation tools are quite young), but I hope they exist, nonetheless.
Sincerely,
Greg Smith
