To get you started we will begin by examining the various methods that are commonly used for treads and we’ll look at why these methods often fail, then we’ll look at a unique method of doing it that overcomes these problems. Finally we’ll go through the process of actually building a whole tank tread system that works!

What you’ll learn:

• Compare several common methods for tank treads and learn their downsides
• How to overcome the common problems
• Learn how to use vertex parenting for perfect treads that don’t deform
• Make use of curve modifiers and constraints to build a functioning tank tread
• Build a tread system with automatic steering
