Are you crafting custom content for Minecraft? If so, be sure to download the map called Particles (PARTICLES).
The custom map Particles (PARTICLES) is not designed for creativity or survival in Minecraft Bedrock Edition. The creator of this world has compiled an entire library of effects that can be found within the game.
Features of the PARTICLES Map
The map features an extensive gallery (which is also well-designed in Minecraft BE) adorned with blocks. Once activated, particles linked to each block will appear. Just remember to deactivate them; otherwise, the performance of your game may lag towards the end of your session.
