How to Install and Enable the No Block Break Particles Pack
Placing the Pack Correctly
This is a resource pack, not a mod, so it does not go in your mods folder. Open your Minecraft installation folder and locate the resourcepacks directory. Drop the pack file (a .zip) directly into that folder without unzipping it. If you extracted it, Minecraft will not read it.
Activating It In-Game
Launch the game and go to Options → Resource Packs. Find the pack in the left column (Available) and move it to the right column (Selected). Make sure it sits above any other pack that also touches particle textures, otherwise the other pack will override it. Click Done.
Confirming It Works
Enter a world and break a dirt or stone block. If you still see the usual scatter of fragments, check that no other pack is layered on top of it. You can also open Options → Video Settings → Particles and set particles to All to confirm the pack, not the setting, is what removed the visuals. If particles are set to Minimal, you may not notice a difference either way.
Keeping It Applied
Resource packs are per-profile, so if you switch between installations or profiles, reselect the pack in each one. It stays active across worlds once selected.
