Parenting the tracks
We will now parent the tracks to the tank and translate tank movement into track rotation. This way, movement of the hull will result in rotation of the empty sphere, which will in turn cause all the wheels and tracks to move. In the next few steps, we will bind the tracks to the rest of the tank using constraints:
- Create an empty cube and scale it so that it completely contains the tracks:
Figure 11.22 – Empty cube
- Parent all the objects, including the empty sphere and the track curve, to the empty cube:
Figure 11.23 – Parenting to the empty cube
- Rename the hull of the tank as
Hull:
Figure 11.24 – Renaming the hull
- Parent the empty cube to the hull by selecting the cube, then the hull, and pressing Ctrl + P:

- Add a Transformation constraint to the empty sphere...
