Map Seed

The Map Seed determines the map shape. Using the same seed with the same parameters will generate an identical map, so it's helpful to specify this when you desire repeatability. You can specify a numeric value and/or text if that's easier to remember. The value you set here is saved in the Action when the map is generated.

Selecting Random will generate a new random value when you click the Generate Height Map button, but again, that value is saved in the Action that is generated.
