uNmINeD 0.14.3 – Zoom

  • Post comments:2 Comments

New uNmINeD development snapshot is available for download!


  • Added blocks from latest Minecraft 1.17 snapshot 21w08b
  • Added zoom in levels for image export
  • Added zoom in levels for web export
  • Added mouse coordinates to web map
  • Increased max zoom out level
  • Fixed int32 overflows caused by very far regions
  • (CLI) Added zoom range options for web export (--zoomin, --zoomout)
  • (GUI) Reduced memory usage
  • (GUI) Fixed memory leaks
  • (GUI) Fixed crashes while changing zoom level
  • (GUI) Fixed empty browser when adding a single world folder

uNmINeD now ignores insanely far regions with block coordinates greater than ±67 million to avoid int32 overflows in calculations. This limitation is unlikely to cause any problems since in-game world border is at ±30 million.

New uNmINeD development snapshot is available for download!

This release contains macOS related fixes for the GUI version.


  • (macOS GUI) Changed packaging to an easy to run/install app
  • (macOS GUI) Fixed wrong Minecraft saves path

My friend in a galaxy far, far away finally managed to install macOS inside a virtual machine running on his PC, so now I can test uNmINeD on macOS.

Installation instructions: extract the downloaded tar.gz and start the application (or move it to Applications and start from there).

Required macOS version is 10.13 High Sierra or later.

[WIP] Selection and overlays

  • Post comments:4 Comments

I’m working on a selection tool to make image export easier and to support other upcoming features:

Developing a rectangle selection tool

The new rendering workflow makes possible to implement various overlays based on any chunk information like data version, status, last update, inhabited time, entities, or the amount of a given block type.

This is a heat map showing inhabited time (how long the players have been in the area):

uNmINeD 0.14.1 – Optimization

  • Post comments:6 Comments

New uNmINeD development snapshot is available for download!


  • New chunk processing and rendering workflow
  • Added I/O scheduling
  • Optimized block name pattern matching (faster stylesheets)
  • Improved support for worlds with negative Y (Minecraft 1.17)
  • Fixed missing zoom out tiles in generated web maps
  • (CLI) The --area parameter now accepts block, chunk and region rectangles

uNmINeD now reads region files one by one and sequentially instead of random access. This has a huge impact on chunk read times on hard disks (5-10x).

uNmINeD now also have a new task scheduler and a new render pipeline with some buffering that allows reducing the number of chunks that need to be read and processed more than once.

Value of the –area parameter can be a block, a chunk or a region rectangle. The rectangle can be specified using two points (top-left and bottom-right corners of the rectangle), or using one point (top-left corner), and a size (width, height).



The bottom and right edges specified by the point (x2,z2) are exclusive, they are outside of the rectangle.
