In addition to side projects like this one, I am currently training myself in the Unreal Engine! My past experience with programs like MAX, Rhino 5, Maya, Cinema 4D and video games, I find that I really like the interface and the free camera is very familliar. I am currently getting the hang of the blueprint editor, which has some similarities to the MAX programming layout.
I added the second parts to the rig and I'm happy with the progress.
The main purpose of this rig is test my level of designing at high complexity.
