uNmINeD 0.14.1 – Optimization

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.

    I’m not sure if this is a bug from the software but in night mode there is an unlit section in the middle of an otherwise brightly lit area. I’ve tried adjusting the y position of the light sources in the unlit area in-game without much success. What kind of parameters determines what is illuminated in night mode?
    Thanks for your continued work!

      uNmINeD uses block light information stored in saved chunks to render night maps.
      Sometimes this light data is missing or messed up by Minecraft.
      Sometimes it’s a bug in uNmINeD.
      Can you show me a repeatable test case? How the light sources and other blocks need to be placed to cause unlit sections in uNmINeD?

    Thanks so much. I have a 1.17 snapshot server and Unmined now lets me look at the map that’s generated so far. One thing that would be really nice, is if coordinates could show on the leaflet map because when you get really far out it’s hard to find your way back because it’s not possible for example to zoom out enough when you’re at x= 80000 and then to find your way to other areas that you know the coordinates of. Of course a higher zoom-out option would do it too. Other than that Unmined is super in every way and thanks so much for your hard work.

      Version 0.14.3 released today has coordinates on the leaflet map.
