Follow Path Constraints
Follow Path constraints allow an object to use a target Bézier curve as a path. When the Bézier curve's path constraint is animated as a channel animation, this affects the object's position. If the option Align to path is checked, it also affects the object's orientation.
The object follows the Bézier path starting from the path's start point and progressing in the same sense as the path. You can change the start point by:
Right-clicking on the Bézier path where the start point should be placed and selecting Place start here.
Modifying the Position along path setting below the list of constraints. Provide location along the Bézier curve by entering a percentage of the curve.
If the option Align to path is checked, the object will rotate so that its face is always oriented in the direction of travel along the Bézier path. Below the list of constraints, you can define:
Setting | Default | Description |
|---|---|---|
Aim axis | local X axis | Defines the local axis of the object's pivot that is oriented towards the direction of travel along the Bézier path. |
Up vector | local Y axis | Defines the local axis of the object's pivot that points upwards. |
