Some time ago I started modeling Robocop 2 Cain.
Still working on it but I made also couple rigging tests.

Check out some rigging tests I made:

BTW. Everything modeled and rigged in Houdini.

Amazing!!! I just love those mech stuff! Very detailed and clean model.

Gorgeous!
You must have watched Robocop 2 more times than I did!
