Having subscribed another month of ProRigs in April, there are always little thing to learn. For example, the outsole of a running shoe is usually a bit off the ground. In the past I would see it as pure flat. In their rigs I found that a simple extra set-driven-key is added at the very start during the foot roll. The action is more believable with this tiny detail.
I came across an impressive reel by Mateusz Poplawski https://vimeo.com/mpoplawski This is inspirational on how rig features could be shown in a concise way. Recently I’m checking with the characters by ToyRig www.toyrig.com. Not only they are free, the smearing feature is amazing. Just like some of the rigs some joints and meshes are locked and hidden. So if you want to see them for study purpose, open the file in an editor. Search with the hidden node name. The answer is quite obvious 😀
