Improper's 3D Minimap
by ItziSpyder
Improper's 3D Minimap draws a radar-style map with 3D terrain, letting players see the blocks around them while caving.
What it does
The minimap renders terrain in three dimensions, with filled voxels for full blocks and separate drawing for non-full blocks. Blocks on the same y-level as the player are shown in light gray, and block entities are drawn as well. A radar view adds entities, and a target selection menu controls which of them appear on the map.
The mod is built for survival caving, and its author notes that it was used on multiplayer servers. Server owners should check the server rules before using it, since a mod that reveals terrain can be treated as a bannable offense there. Two render modes are included, and map coloring by block type can be disabled.
Installation needs Fabric API, which must be present alongside the mod. Improper's 3D Minimap is client-side only, so the server does not need it. It is open source under the MIT License and is published for Fabric, covering 1.21 – 1.21.5 with the latest file for 1.21.5.
