This plugin allows you to show an overlay around some blocks like the famous xray mod but it doesn't require any modification. It doesn't use entities and doesn't require a resourcepack (a pack is still recommended in 1.17 to allow more colors).

The plugin is opensource and you can rebuild it for free from the sources.

You need the permission xray.command to be able to use the /xray command. You can configure the available blocks from the config.yml (this supports oraxen custom blocks).


Because of https://bugs.mojang.com/browse/MC-234030, you won't be able to use red and blue colors in 1.17 and 1.18. This can easily be fixed using this resource pack changing core shaders: https://cryptpad.fr/file/#/2/file/lJ+if1l6xolulYrV55OjOmi5/

This plugin will soon add a player mechanic to the Oraxen plugin.
