You can find the Planetary Installations Settings Configuration File in MySaveWorldFolder\Storage\1521905890.sbm_ModularEncountersSpawner\Config-PlanetaryInstallations.xml. The settings you can modify are listed below:
This setting allows you to specify the cooldown time (in seconds) after a Planetary Installation appears before another one can appear for the player. Value can be any integer number (should not be 0 or lower)
This setting allows you to specify how often the script should measure the player's distance to see if they've travelled far enough to trigger a Planetary Installation spawn. Value can be any integer number (should not be 0 or lower)
This settings allows you to specify the distance a player must travel in space before a Planetary Installation will spawn. Value can be any number (should not be 0 or lower)
This setting allows you to specify if there can should be a maximum amount of Planetary Installation grids near the player area. The AreaSize property below specifies the radius to check. Value can be replaced with any integer number (no lower than 0).
This setting allows you to specify the area to check for existing Planetary Installation if MaxShipsPerArea is set to true. Value can be any number (should not be 0 or lower)
This setting allows you to specify the maximum altitude from the surface the player must be for a Planetary Installation spawn event to trigger. Value can be any number higher than 0
This setting allows you to specify the minimum distance from the player that the station(s) will appear. Value can be any number higher than 0 and lower than MaximumSpawnDistanceFromPlayers
This setting allows you to specify the maximum distance from the player that the station(s) will appear. Value can be any number higher than 0 and higher than MinimumSpawnDistanceFromPlayers
This setting allows you to specify if the mod should perform terrain checks in 8 directions from the player. If set to false, the mod will only perform checks in 4 directions, which may result in a lower chance of finding a suitable spot to spawn the station(s). Value can be true or false
This setting allows you to specify the distance to the next terrain surface check area if a previous check fails. Value can be any number higher than 0.
This setting allows you to specify the minimum distance from other grids and players the station spawn coordinates must be. Value can be any number higher than 0.
This setting allows you to specify the minimum terrain variance that is allowed when checking a potential area for spawn coordinates. Value can be any number lower than 0.
This setting allows you to specify the maximum terrain variance that is allowed when checking a potential area for spawn coordinates. Value can be any number higher than 0.
This setting allows you to specify if the mod should check a potenial spawning area in 8 directions to ensure the terrain is level (using MinimumTerrainVariance and MaximumTerrainVariance). If set to false, only 4 directions will be used, which could result in more uneven terrain being used to spawn stations. Value can be true or false.
This setting allows you to specify how far each directional step from the proposed spawn coords should be checked. Value can be any number higher than 0
This setting allows you to specify the base chance a medium station has of appearing instead of a small station. Value can be any integer number between 0 and 100.
This setting allows you to specify how much the MediumSpawnChanceBaseValue increases for every small station that spawns. Value can be any integer number between 0 and 100.
This setting allows you to specify the additional distance from players that is added to MinimumSpawnDistanceFromPlayers and MaximumSpawnDistanceFromPlayers when spawning a medium station. Value can be any number higher than 0
This setting allows you to specify the base chance a large station has of appearing instead of a medium station. Value can be any integer number between 0 and 100.
This setting allows you to specify how much the LargeSpawnChanceBaseValue increases for every medium station that spawns. Value can be any integer number between 0 and 100.
This setting allows you to specify the additional distance from players that is added to MinimumSpawnDistanceFromPlayers and MaximumSpawnDistanceFromPlayers when spawning a large station. Value can be any number higher than 0
This setting allows you to specify if the spawn group frequency should be set no higher than a provided value. The MaxSpawnGroupFrequency value would be the frequency used if the spawn group frequency is above that value. Value can be set to true or false
This setting allows you to specify the spawning frequency of Planetary Installations if UseMaxSpawnGroupFrequency is set to true. Value can be replaced with any number (no lower than 0).
This setting allows you to specify the minimum distance players must be from the encounter before despawn is triggered. Value can be replaced with any number (no lower than 0).
