Car Rig

The plan was to rig a car for steering, wheel rotation and drifting control. However, I only manage to get along with steering part.

First I created dummy for wheel hubs from create->helpers->dummy window. It was aligned with the first wheel using align tool. Then I copied the dummy and aligned other as well. All four wheel were linked to the dummies that was suppose to provide wheel rotation. Extra two dummies where create for front wheel steering. In front of them to more dummies were created. Previous dummies were constrained to new dummies with lookAt constrain. Therefore, when new dummy is moved the previous wheel dummy rotates to that direction. Then i created the steering wheel control and linked steering dummies to it. The whole car body group and dummies were linked to one dummy so i could have separate objects and still move everything together. Then i created a control for it and assigned the dummy to it. The control were created in separate layer as also the dummies. In the end car model consisted of three layers. One for car objects, other for rig-dummies and third for controls.
