The Galaxy effect creates a spiral like effect that expands around the model either clockwise or counterclockwise. Used most effectively on models such as a mega tree or a matrix.

One or multiple colors can be used for the effect. If multiple colors are selected, than the spiral will be made up of the selected colors.

| Options/Settings           | Description                                                                                                                                                |
| -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Start: Center X,Y**      | Defines the x and y coordinates of the center (i.e. focus) point of the galaxy effect.                                                                     |
| **Start: Radius**          | Defines the lower radius of the galaxy.                                                                                                                    |
| **Start: Width**           | Controls the width of the lower end of the spirals.                                                                                                        |
| **Start: Angle**           | Controls the angle of the spirals.                                                                                                                         |
| **End: Radius**            | Defines the upper radius of the galaxy.                                                                                                                    |
| **End: Width**             | Controls the upper width of the spirals.                                                                                                                   |
| **End: Rev’s**             | Determines the number of full revolutions each arm makes in the given timeframe.                                                                           |
| **Options: Head Duration** | Controls the swell i.e. the amount of time that the head of the spiral uses.                                                                               |
| **Options: Acceleration**  | Sets the speed of a non-linear movement for the head color and body.                                                                                       |
| **Options: Reverse**       | Reverses the direction of the rotation of the galaxy effect.                                                                                               |
| **Options: Blend Edges**   | Each edge blends to black. Turning it off converts the galaxy effect to a full circle at the end of the rotation.                                          |
| **Options: Inward**        | If the spirals overlap, it determines if the spirals will appear to be moving inward or outward. If there is no overlap, this setting will have no effect. |
