This effect reverses the direction of ring growth. If the rings were expanding, they immediately begin contracting at the same speed, and vice versa. A similar effect can be achieved by changing the sign of the Ring Growth parameter, but the Reverse command is much more convenient.
Reverse is handled separately from the Ring Growth parameter, and does not alter it; they combine to determine ring behavior, as shown below:
| Ring Growth | Reverse | result |
|---|---|---|
| positive | no | expansion |
| positive | yes | contraction |
| negative | no | contraction |
| negative | yes | expansion |
| zero | N/A | frozen |
