Been building a rig, to 8 characters in a few days. I have to prove they work to Unreal Engine to render nicely - which they do. That little extra graphical pop goes a long way for clients. So far, it's fun. My staff will stay the night, and we are working in a relaxed "sprint" like method, with long breaks between. It has been good. But the deadline is creeping up on us really fast - not to mention all the other projects in play.........
