This compound orients particles in the direction of their movement (velocity). This is useful for setting up anything that
needs a specific orientation relative to its movement, such as birds, arrows, or objects following along a curve.
Plug this compound's Execute output into a Port on the ICETree node.

The vector that is used to align the particles. The Y axis is typically the vector that points along the length of the particle,
depending on the shape of the particle. If you change your particle shape to a cone, you can see that the Y axis is the direction
of the cone point. The X and Y axes are the sideways axes.

Defines how much the particle is rotated each frame. The value is a ratio, so if you set it to 1.0, the particle is immediately
aligned. If you set this value to 0.1, the particle rotates by 10% each frame.

Toggles the limiting of the rotational velocity to the value you specify for the Max Rotational Velocity. Turn this option off so that there are no restrictions to the particle's rotational velocity.

|
|
This is the maximum rotational velocity value that the particles can reach. This helps prevent particles from spinning too
much when they are going very fast.
