The EarthMC map has many known issues with Dynmap such as, incomplete render, only rendering where players have visited, or not rendering leaves and other foliage. This is a result of how the map was made and is not an issue with Dynmap, luckily there is a fix.

1. Download the WorldBorder plugin: https://www.spigotmc.org/resources/worldborder.60905/

2. Pause Dynmap: /dynmap pause all

3. Set the world border radius and center: /wb [worldname] set [radiusX] [radiusZ] [X] [Z]

• [worldname] is the name of the world you want to set the border in.

• [radiusX] is the horizontal radius of the world border

• [radiusZ] is the vertical radius of the world border

• is the horizontal center point of the world border

• [Z] is the vertical center point of the world border

4. Run worldborder with the force flag: /wb [worldname] fill [freq] [pad] [force]

• [worldname] is the world you want to be pregenerated

• [freq] is how many chunks a second are generated, 20 is the default. WARNING: setting this too high will cause server lag

• [pad] how many chunks beyond the border to generate, this makes sure that if a player visits the border, all chunks are already generated. The default is 208, We recommend setting this to 0 for EarthMC.

• [force] This must be set to true

5. Wait for worldborder to finish

6. Unpause Dynmap: /dynmap pause none, you may have to start the fullrender using /dynmap fullrender [worldname]

@talwat it works fine, just because the last update was a few years ago doesn't mean it is bad or you shouldn't use it, worldborder is one of only 2 plugins that I know can fix those issues.

I'm experiencing this too, and even after doing this it hasn't fixed it.

Also, worldborder hasn't been updated in 5 years, don't use it.

What does the worldborder fix actually do? Does it force load chunks once? Does it pre-generate them? I'm confused on this.

That is also explained on the worldborder wiki, but it will bring all the chunks in it's set range to their last generation state so dynmap can render them.

I tried squaremap and it worked flawlessly, so I think it's a dynmap problem.

Was there a commit in dynmap that fixed this problem?

No, but the aforementioned way of using worldborder works, and we are not going to implement chunk generation in dynmap, so not planned
