Activating Cosinus Shaders in Video Settings

Selecting the Shader Pack

To view the wavy math effects in game, you must enable the pack through a compatible shader loader such as Iris or OptiFine.

1. Press Esc to open the pause menu and select Options.

2. Click on Video Settings, then choose the Shader Packs (or Shaders) menu.

3. If you have not added the pack file yet, click Open Shader Pack Folder and place the shader file inside.

4. Locate Cosinus in the list of available shader packs and click to select it.

Applying and Verifying the Effects

Once highlighted, click Apply or Done to reload the game's rendering pipeline. Return to your world to verify that the shader is working.

When loaded, your ordinary blocky surroundings will immediately warp into wavy landscapes driven by cosine math functions. If the screen remains standard and flat, reopen the shaders menu to confirm that the pack is actively selected and that your shader loader is toggled on.
