• Bedrock LevelDB log file reader optimizations (speedup for worlds with large log files)

• Isometric mode now uses the block filter settings
• Added support for Java Edition default blockstates (from 26.3-snapshot-7)
• Upgraded to .NET 11 (preview.7)

Default blockstates

Minecraft Java Edition from version 26.3-snapshot-7 does not store blockstate properties in the world save files when referencing a default blockstate. This caused these blockstates to render incorrectly.

uNmINeD now uses a configuration file config/vanilla.defaultblockstates.java.txt to resolve default vanilla blockstate properties. If it encounters a blockstate reference without properties, it will use the default properties from the configuration file.

The configuration file only contains default blockstate information for vanilla blocks. A mod will be available later that will allow you to generate a blockstate configuration file for modded worlds.

Block model handling

uNmINeD now can read and use 3D block models from Java Edition client JARs and datapacks, and render them in 2.5D top-down and isometric views.

Bedrock Edition does not have 3D block models available for external tools, so uNmINeD uses Java block models to render Bedrock blocks. You will need a Java client JAR file to make this work. You can download it even if you do not have Java Edition, the original Mojang download links are available on GitHub, scroll right to see the client JARs.

Assigning Java block models to Bedrock blocks is controlled by config/bedrockmapping.json. The content of this file is largely based on information extracted from the Chunker project.

Bedrock fences, stairs, glass panes and other connecting blocks may render incorrectly if you have a version older than 1.26.40, because the required information is not present in the world save files.

Block model rendering mode

This is a preview of a new feature under development.

uNmINeD now can render 3D block models to draw blocks instead of using single colors.

• It works at 4:1 or higher zoom-in levels
• It works with shadows
• It works with image and web export
• It does not need a GPU (uses only CPU)
• It requires a Java Edition client JAR file even if you use it with Bedrock worlds.

Use the --blockrender=true command line parameter to enable block model rendering in the CLI.

Isometric rendering mode

This is a preview of a new feature under development.

uNmINeD now can render an “isometric” (axonometric) 3D map.

• It only works at 16:1 zoom-in level (other zoom levels coming soon)
• It has multiple view angles
• Image and web export not yet available
• It does not need a GPU (uses only CPU)
• It is only available in the GUI (CLI will come later)
• Shadow rendering will come later
• It requires a Java Edition client JAR file even if you use it with Bedrock worlds.

Notes and known issues

Block model rendering is a new feature under development. There are a lot of bugs, glitches and unfinished stuff. The code is not yet optimized for speed, upcoming releases will be faster.

Some of the most visible known problems:

• Some 3D block models are not rendered correctly or not visible at all
• Waterlogged blocks are rendered as dry
• Custom (modded) Bedrock blocks are not rendered at all
• Ambient occlusion shading in isometric mode does not work at chunk borders
• Blocks do not cast shadow on themselves
• Terrain elevation shading is applied incorrectly
• Water settings are ignored
• Water transparency is not supported in isometric mode

Changes:

• (Minecraft) Reworked datapack and mod handling
• (Minecraft) Textures now can be used with Bedrock worlds (experimental)
• (Minecraft) Colors for custom/modded blocks now can be calculated automatically from textures
• (CLI) Textures now can be used with the CLI

Automatic colors for custom blocks

uNmINeD now can read biome and block metadata from datapacks/mods and behavior/resource packs, and it calculates map colors for custom blocks automatically by averaging their textures instead of displaying them as pink.

Textured rendering

By default, uNmINeD displays each block as a square filled with a single color. When textured rendering is enabled, it still does not render blocks in 3D, instead it fills the squares with an image (the in-game texture of a block) rather than a solid color.

Textured rendering can be enabled on the render settings side panel (the tab with a cog wheel icon). It works for zoom-in levels 4:1 or higher. It works well with cube-like blocks, but fences, walls and other blocks with a complex 3D model look off. Upcoming releases will be able to render fences and walls correctly, and images to be used for complex blocks will be customizable.

Usage with Java Edition

Using textures or datapacks/mods with Java Edition worlds requires a Minecraft client JAR file. If you have Minecraft installed, uNmINeD will automatically find your client JAR file, otherwise you have to copy it from another machine, and select it in uNmINeD’s app settings.

Usage with Bedrock Edition

Using textures or behavior packs with Bedrock Edition worlds requires a vanilla resource pack. You can download it from Mojang: https://github.com/Mojang/bedrock-samples/releases. Find your version (or use the latest), click on Assets, and download the full package named bedrock-samples-xxxxx-full.zip (or the source code zip package, either one is good), then select the downloaded file in uNmINeD’s app settings.

CLI usage

Use --java-client-jar=/path/to/1.21.11.jar to select your Minecraft client JAR.

Use --bedrock-vanilla-pack=/path/to/bedrock-samples-v1.26.0.2-full.zip to select your vanilla resource pack.

Use --textures=true for textured rendering (effective at zoom-in levels 4:1 or higher).

Selecting a client JAR or a vanilla resource pack is required for all datapack related functions, including automatic color calculation for custom blocks and textured rendering.

Changes:

• (Minecraft) Added and fixed a lot of building block colors
• (Minecraft) Fixed Java Edition region loading issues that were occuring on some systems
• (Hytale) Added support for RocksDB world storage type (thanks to rocksdb-sharp)
• (Hytale) Map colors are now calculated based on in-game textures
• (Hytale / GUI) Added Hytale player markers
• (GUI) Added export functions to the block list panel

uNmINeD now uses different colors for each Minecraft stone type (basalt, diorite, andesite, etc.), and the color of stone and cobblestone blocks are now darker to better match the in-game color. Many other blocks now have a distinct color (gold, lapis, diamond, etc.). If you want to go back to the previous map colors, turn off the Natural stones, Masonry and Mineral blocks settings on the stylesheet sidebar tab.

Hytale support is still experimental. There may be bugs and crashes.

About the block finder

The new block finder feature of the CLI scans the world for a specified block and displays the coordinates or writes them to a CSV file. You can use the --area, --topy and --bottomy arguments to limit the search area in the same way as with mapping functions.

Usage examples:

1. Write coordinates of all bell blocks to a file:

unmined-cli blockfind dump --world="path_to_my_world_folder" --block=minecraft:bell --output=results.csv

Warning! The result file can grow extremely large if you search for a common block. If the file already exists, the results are appended instead of overwriting the file.

Result:

BLOCK;STATE;X;Z;Y
minecraft:bell;powered:false,attachment:floor,facing:south;68;2;62
minecraft:bell;powered:false,attachment:floor,facing:north;1079;1083;76
minecraft:bell;powered:false,attachment:floor,facing:north;1993;371;72
minecraft:bell;powered:false,attachment:floor,facing:north;29;-1495;71

2. List all deepslate ores to console:

unmined-cli blockfind dump --world="path_to_my_world_folder" --block=minecraft:deepslate_*_ore --log-console=false

Note: the --log-console=false argument should be used to disable logging to the console when the output is also displayed on the console. You can use the --log-file argument if you still need the logs.

Result:

BLOCK;STATE;X;Z;Y
minecraft:deepslate_diamond_ore;;196;1220;-56
minecraft:deepslate_lapis_ore;;34;1710;-51
minecraft:deepslate_lapis_ore;;34;1710;-50
minecraft:deepslate_gold_ore;;34;1711;-55
minecraft:deepslate_diamond_ore;;176;1076;-56
minecraft:deepslate_diamond_ore;;176;100;-49
minecraft:deepslate_diamond_ore;;176;101;-49
minecraft:deepslate_redstone_ore;lit:false;176;104;-54
...

3. Customizing output format:

unmined-cli blockfind dump --world="path_to_my_world_folder" --block=minecraft:bell --log-console=false --csv-header=false --csv-separator="|" --csv-fields=x,z

• --csv-header=false disables the CSV header
• --csv-separator="|" sets the | character as field separator
• --csv-fields=x,z sets the output format to contain only x and z coordinates

Result:

68|2
1079|1083
1993|371
29|-1495
