A free mod for Valheim, by Slothsoft.

Improve your exploration experience with this mod developed for the game Valheim. This helpful mod adds the avatar’s line of sight to the map uncovering algorithm. It has cool features that will give you a more realistic experience while playing.

With this mod, the map is not just uncovered where you are but also where you’re looking. Terrain and other high structures will be blocking your view, so you will have to climb over a mountain to uncover blocked areas near you. And just like in real life, food reduces the view distance, so you will have to wait for a sunny day before going on an adventure.
