you can extract the sub file from a save game, make it a new local mod, edit it in sub editor, repack and load the save. other than that you could copy the item file of this mod and make a new one, just changing the name back to vanilla and adding the overwrite tag, ive never done the latter but on the games discord people will know if you ask.

darn! is it craftable for use in games-in-progress?

or is there any way mods like this one that modify the base nav stations?

it doesnt overwrite the vanilla terminal, its an additional item you'd have to put on a sub manually

i downloaded this and didn't notice any difference in visible range at the nav terminal. i wasn't able to zoom out the sonar screen any further than without this mod.

Many thanks

its for enemy detection, they each have different values for sight and hearing range which you can check in the creature editor or wiki, this is how far away they can spot you. i assume static sight means having active sonar on/off doesnt change visual range, fade i have no idea

I just found that I simple edited wrong items. But thanks.
What does<aitarget sightrange="200" soundrange="10000" staticsight="true" fadeouttime="5" />this mean?

it is this bit right here:
<aitarget sightrange="200" soundrange="10000" staticsight="true" fadeouttime="5" />
<Sonar canbeselected="true" range="16000" powerconsumption="100" displaybordersize="-0.1" allowuioverlap="true">

(AI) soundrange and (sonar) range being the important ones

How do you make this? I added range="20000" to my navigation terminal and nothing happened.
