This a quick animation of my Blender Tank Tracks, its still a Wip I hope to add other features and Dynamic phisics.
It uses a similar technique as my Ant rig to orentate its self correctly. But the major issue I had with the tank track was getting the track to interact with the floor.
The red and blue track segments are so you can see the track is rotating rather than stepping like some other Track solutions.
