Minecraft Bedrock server worlds can be modified to include a resource pack or 'shader'. This pack can be added to existing worlds, but it is best done on completely new ones. These packs can drastically change the graphics for Minecraft and require users to enable the new vibrant visuals option. Shaders vary slightly from addons/behavior packs; they don't add mechanics or items, only visuals, to the game.
Note: Make a backup of the existing world before installing a shader pack.
