Spline Follower
Method #
This node translates a child object along an input spline. The child may also optionally be rotated to point along the direction of the spline.
Parameters
These properties control the core behaviours of the node.
Parameter Details Spline Time The percentage along the spline the child nodes will have moved along, in relation to the “Spline Time Mode” dictated in the input spline. If set to “Knot”, the spline will move up by 1 per control point.
Rotation Follows Direction Toggle whether the rotation of the objects on the spline follows the direction.
Rotation Look Ahead Time How far ahead along the spline the child nodes should rotate towards.
Follower Rotation - Heading / Pitch / Bank Control which axis of rotation are used in the rotation.
Use Matrix Rotations Generate the rotations via transform matrices. This may be more accurate as unlike the euler angle method it does not suffer from gimbal lock - but it is less controllable, as the rotation channels cannot be accessed or controlled separately in this mode.
Fix Heading Rotations Try to solve flips in the heading direction as the object moves around the spline.
