Changing the size of the players map vision.

[Scintillates]

Hello everyone, I'm looking for some help in the right direction in regards to editing the reveal radius players can see when they open up the map. This is because for a world that is figured to 'Only night' the map reveal radius shows more than the player can see with a light source. So far I've looked into sentryward.lua (ocuvigil) for some guidance on how it reveals itself in the map but I'm not seeing anything that can help me change the items reveal radius.

Any help would be appreciated thank you!
