How to Turn On Optional Path Tracing for Caves and Interiors

Path tracing in CTMPOMFIX Chocapic13′ is optional, letting you choose between higher frame rates and realistic light behavior. Turning it on changes how illumination interacts with walls, ceilings, and underground spaces.

Activating Path Tracing in Shader Settings

You can toggle path-traced lighting directly in-game through your shader loader:

1. Pause the game and open Options, then Video Settings.

2. Open the Shader Packs menu where CTMPOMFIX Chocapic13′ is active.

3. Click the shader pack settings button to view its customization options.

4. Find the lighting or path tracing section, switch optional path tracing on, and apply your changes.

Where Path Tracing Makes the Biggest Difference

With path tracing enabled, light bounces naturally around corners and casts soft shadows instead of stopping sharply at block edges. You will see the clearest difference inside caves and enclosed builds, where light from torches, lava, or small window openings reflects off nearby surfaces to softly light dark corners. Because calculating natural light bounces takes extra graphics power, you can return to the shader settings menu whenever you want and turn optional path tracing back off for smoother everyday gameplay.
