Activating Doom Shaders in Your Video Settings

Accessing the Shader Menu

Before loading into your world, ensure you are running a compatible shader loader such as Iris or OptiFine.

1. Press Esc while in-game to bring up the Game Menu.

2. Click on Options, then select Video Settings.

3. Locate and select the Shader Packs (or Shaders) menu option.

4. If Doom Shaders is not visible in the selection list, click the button to open your shaderpacks folder and confirm the pack file is present.

Applying the Shader Pack

Once the shader list displays Doom Shaders, you can enable it directly:

1. Click on Doom Shaders in the list to select it.

2. Click Apply or Done to confirm the change. The game screen will briefly reload as the new lighting profiles take effect.

3. Return to your game to verify that the lighting has transformed.

You should immediately see clean shadows appear beneath your character and surrounding blocks while maintaining the classic, blocky appearance of the base game.
