Yes! I made another Ratchet model! This time I rigged him up. It really screwed up (the rig in his arms grabbed onto the geometry in his cheeks, which pulled the cheeks down with the arms so I covered the cheeks up with his arm haha), but eh, at least it kinda worked out in the end.
I didn't model his chest brace thing because I didn't want to spend any more time on it knowing that it wouldn't be animateable.
I still don't have a fully animateable Ratchet model, this is definitely no good for animation but I will keep trying to learn Maya, and I will keep going until I can make cool models which are fully rigged and animateable!
