BlueMap

Copper-chests and coppergolem statues models.
And reverted the integrated webserver changes from 5.12.
(There are some issues with using virtual-threads in combination with a database-storage that could lead to the webserver becoming unresponsive. This issue is resolved when using Java 24+ but as long as BlueMap still supports Java 21 we revert to the previous webserver implementation)

Upgrading from 5.12

Replace the bluemap.jar-file with the new one

Changelog since 5.12

Added models for copper-chests
Added models for coppergolem statues

Highlights / Notes

This is a one-off backport of BlueMap 5.12 for Forge 1.20 - 1.20.4 (including 1.20.1) due to very high demand.

This Version needs Java 21 to run!
Forge and most mod's should be able to run on Java 21 instead of Java 17. If you can't use Java 21, then you need to use BlueMap 5.3 instead.

Upgrading from 5.3

The previous BlueMap version that supported Forge 1.20.x was 5.3, so you are likely upgrading from there.

There have been a ton of changes and new config values etc., so I really recommend you to do a full clean installation of BlueMap:

Stop the server
Make a backup
Delete your current ./mods/bluemap-x-yz.jar
Delete the ./config/bluemap
Delete the ./bluemap directory
Put the new bluemap-5.12-mc1.20-6-forge.jar in the ./mods folder
Start the server
Reconfigure BlueMap again, using the newly generated configs
You can keep the configs from your backup aside, to help you with the porting
run /bluemap reload

If you don't want to do a clean installation to keep your currently rendered maps, you need to follow the upgrade-steps from these changelogs:

Highlights / Notes

With Render-Masks it is now possible to limit your map render to all kinds of shapes and perfectly control what you want to be visible on the map, and which regions should remain hidden.

Upgrading from 5.10

Replace the bluemap.jar-file with the new one
Delete your <webroot>/index.html to make bluemap update the webapp
You will need to update your map configs!
- Find the section with min-x, max-x, min-z, max-z, min-y and max-y in your map config file, e.g.:
```
#min-x: -4000
#max-x: 4000
#min-z: -4000
#max-z: 4000
#min-y: 50
max-y: 90
```
  and add render-mask: [ { before, and ] } after the section, e.g. like this:
```
render-mask: [ 
  {
    #min-x: -4000
    #max-x: 4000
    #min-z: -4000
    #max-z: 4000
    #min-y: 50
    max-y: 90
  }
]
```
  -> here is a video-example
- Optionally, you can add the new edge-light-strength: 15 property to your map config as well
