The mini-map with a twist!
- A clientside-only, highly configurable isometric 3D mini-map with a twist, it only tracks the blocks you've stepped on.
- Has waypoint support and multiple map types. However, the mod is optimized for mainly Blocksteps map type.
- This was an experiment turned mini-map. It may not have the best performance but the community voted it into existence! There might not be much I can do about performance issues outside of the Blocksteps map type.
- Also, if you return to somewhere from far away (eg, another dimension) the map might look like a mess, hit the SHIFT + (Switch Map Mode/Rerender) key to refresh the map.
