Frequently Asked Questions

Does Custom Block Highlight need to be installed on the Minecraft server?

No. Modrinth marks Custom Block Highlight as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Custom Block Highlight require?

Use a file for fabric and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.

Custom Block Highlight is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
