Description

This resource pack makes redstone dust 3D, and adds a beautiful power level indicator. Redstone dust is the only affected block, so I recommend using it alongside my other resource packs like Clean Redstone - main components (put Fancy Dust on top of the resource pack list). The font of the indicators is what you typically find in a vanilla-like 32x resource pack.

This is what it looks like:

If you want to make the indicators use hexadecimal instead, or remove the indicators entirely, you can do so by unzipping the file, and going to Fancy Dust\assets\minecraft\blockstates. Here you will find alternate versions of redstone_wire.json. Remove the original one and rename the version you want to redstone_wire.json.

How to install

After downloading the resource pack, go to options -> resource packs and click the Open Pack Folder button, or open %appdata%\.minecraft\resourcepacks directly. Put the resource pack in this folder. It should then show up under Available. Click the arrow to switch it to the Selected tab and click Done. That's it, the pack should now be installed properly.
