MBL2 Shader Loader (1.21) – Minecraft Bedrock Loader 2

MBL2 Shader Loader is an intermediate pack that allows players to install advanced shaders or textures on Minecraft PE/Bedrock (Windows 10 / Android), which the base game does not natively support. It works by modifying the behavior pack so that the game is forced to load additional .hlsl, .json, or .material shader files from specified directories.

How it works

The basic working mechanism of the MBL2 Shader Loader is as follows:

• When you install the .mcpack, it is added as a behavior pack.
• The ShaderLoader will:
  • Call the configuration file manifest.json → defining the entry scripts and components.
  • Through the Scripting API (Bedrock Script Engine), it points Minecraft to the folder containing the shader (for example: /resource_packs/YourShaderName/).
• As a result, when you open a world, the shader is injected into the rendering process (lighting, shadows, water, fog, etc.).
• Some versions even support automatic shader selection if you have multiple shader packs installed.

Method 1:

1. Download the .mcpack file below.
2. Double-click it to import the pack into Minecraft.
3. Once imported:
   • Go to Settings → Storage → Behavior Packs to check if the pack has been added.
4. Open World Settings → Behavior Packs → My Packs → Activate to enable MBL2_ShaderLoader.
5. Then, install the separate shader you want (if MBL2 doesn’t include one).
   • Place the shader folder in:

     /games/com.mojang/resource_packs/

6. Restart Minecraft → open the world with the activated pack.

Method 2: (Manual installation)

1. Rename the .mcpack file to .zip.
2. Extract it and copy the entire folder to:

   Android: /games/com.mojang/behavior_packs/
   Windows: C:\Users\\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\behavior_packs\

3. Then activate it in-game as in Step 4 above.
