ChunkyMap

ChunkyMap is a map renderer for Dynmap that uses Chunky to render the map tiles. This combines photorealistic rendering with the convenience and automatic updates of Dynmap. ChunkyMap is implemented as a drop-in replacement for the HDMap that comes with Dynmap.

Installation

1. Download the latest jar from the releases page and put it in your plugins directory.

2. Edit plugins/dynmap/worlds.txt and change the class option from org.dynmap.hdmap.HDMap to de.lemaik.chunkymap.dynmap.ChunkyMap for all maps that you want to render with Chunky.
   You can use any perspective and resolution for those maps (list of available perspectives).

   This example worlds.txt for a single map of a world called world might help you:

   worlds:
     - name: world
       maps:
         - class: de.lemaik.chunkymap.dynmap.ChunkyMap
           name: chunky
           title: World
           perspective: iso_SE_30_hires

3. Restart your server (restart not reload).

4. Re-render the worlds you enabled the new renderer for by running the following command from the server console: dynmap fullrender world (replace world with the actual world name).

5. Wait for it… ⌛

6. Wait for it… ⌛ (Sorry, rendering with Chunky takes a while, but it's worth it!)

7. Take a look at your new, shiny maps! ✨

Configuration

The maps can be configured by adding options to the map's section in the world.txt file.

Option	Description	Default
samplesPerPixel	Samples per pixel that Chunky should render. More SPP improves the render quality but also increases render time.	100
chunkyThreads	Number of threads per Chunky instance. More threads will decrease render time but increase the CPU load of your server.	2
texturepack	Texturepack path, relative to plugins/dynmap. Use this option to specify a texturepack for a map. The texturepack in Dynmap's configuration.txt is ignored by ChunkyMap.	None
chunkPadding	Radius of additional chunks to be loaded around each chunk that is required to render a tile of the map. This can be used to reduce artifacts caused by shadows and reflections.	0
templateScene	Path to a Chunky scene file (JSON), relative to plugins/dynmap. Use this option to customize the scene that is used for rendering the tiles, e.g. to change the water color.	None
texturepackVersion	The Minecraft version that should be used as fallback textures	1.16.2
denoiser.enabled	Enable denoising using Intel Open Image Denoise. Only works on Linux	false
denoiser.albedoSamplesPerPixel	Samples per pixel for the albedo map. Setting this to 0 will disable the albedo and normal map.	4
denoiser.normalSamplesPerPixel	Samples per pixel for the normal map. Setting this to 0 will disable the normal map.	4

Example config

worlds:
  - name: world
    maps:
      - class: de.lemaik.chunkymap.dynmap.ChunkyMap
        name: chunky
        title: Chunky
        perspective: iso_SE_30_hires
        chunkyThreads: 2
        samplesPerPixel: 20
        denoiser:
          enabled: true
          albedoSamplesPerPixel: 4
          normalSamplesPerPixel: 4

Ceveats

• Rendering is pretty slow, but I'll improve this by rendering multiple tiles as one image in the future.
• ChunkyMap only works with Bukkit/Spigot at the moment. Supporting more servers would be awesome, though!

Dynmaps that use this plugin

• Craften Server: Lobby dynmap

Building ChunkyMap

1. Get the latest version of Chunky 2. After updating, you'll find the jar file in ~/.chunky/lib (Linux/Mac) or %APPDATA%\.chunky\lib (Windows). Copy the chunky-core-<version>.jar file into the root directory of this repository and rename it to chunky.jar.
2. Run mvn install to install all other dependencies. Chunky 2 can't be installed this way because it's not yet in the Maven repository.
3. Run mvn clean package, the plugin jar will be in the target directory.

Trivia

Originally, ChunkyMap was created as a demo for the RenderService. This service allows rendering the tiles on a distributed network of renderers, which is often faster than rendering the tiles locally.

Ironically, I then implemented support for local tile rendering and removed support for using the RenderService. It will come back in the future.
