this mod pulls the entire worldmap from the seed while also saving chunks as you visit different parts of your world, making it faster than traditional maps. this mod is also compatible with the lost cities mod and modded structures (modded structures might be very less detailed box).
the most important features is that in multiplayer when players go out of your renderdistance it stops displaying them in the map. but in this mod it will always display players no matter where they are (both parties need to have the mod installed).
now compatible with ftb and opac chunks.
different players claimed chunks will be shown in different colors.
you still have to claim the chunks using the mod's own ui or map.
give me more ideas in the comments! :D
