Blocktopograph can map your Minecraft worlds in real-time.
Included map-types: Overworld, Nether, Caves, Slime-chunks, X-RAY, Block-light, Biomes, and more!
The map also provides a intuitive way to edit chunk-NBT-data and teleport players. And markers for every mob!
This is a third-party branch of the previous famous Blocktopograph.
We saw players still want the app to be back so we'd like to continue it after the original version's being out of date.
Huge new progress have been made, and now maps can be displayed 20 times faster, latest map format is also supported well.
