bad news, I have had problems to rig the Tank Track correctly, my knowledge is insufficient, it would be a mistake to give you something that can bring failures when doing some animation.

In a nutshell
I have thought of leaving the Tank Track in a fixed way (that can not move under acceleration) without losing its characteristics, so they will become normal biped legs, with damping and suspension (obvious).

Certainly this makes me sad, but it is a momentary solution, is that I want to deliver many free models for all of you !!!!

What do you think? ✈
