Physics group > Air group > Motion Path

The Motion Path feature makes it possible to precisely control the path that a particle takes after being emitted. This is done by setting keyframes for a comp Light and naming the Light in a certain way.

This keyframed Light lets you control the path that particles travel after being born. Motion Path is useful when precise control of the particle path is needed.

The Number Values

The popup for Motion Path is the only Particular parameter that you will set when creating a motion path. Each of the numbers corresponds a number 'X'. That number is used in the name given to the comp Light that acts as the motion source.

HQ Number Values

In the Motion Path popup there is an 'HQ' suffix of each number; if the Motion Path Light moves extremely quickly, the path is notably linearly interpolated between frames. A path has edges that should be smooth, so if this issue occurs, you should select the HQ variant instead.

Note the HQ setting decreases the speed.
