Use Sobel Shaders for Better Visibility in Caves

Activate the Shader in Dark Areas

The edge detection system works well in caves because it highlights block boundaries regardless of ambient light. The dark outlines remain visible even in low-light conditions, making it easier to navigate underground without relying solely on torches.

Combine with Strategic Lighting

Place torches or other light sources to maintain orientation, but rely on the shader's edge detection to spot cliff edges, lava pockets, and ore veins. The blueprint effect makes height changes obvious, reducing fall damage risks.

Spot Resources More Easily

Ore blocks stand out clearly against stone due to their distinct edges. The shader's outline effect makes it simpler to identify valuable resources like diamonds, iron, and copper without needing to adjust brightness settings.

Navigate Tight Spaces

When moving through narrow tunnels or caverns, the clear edge definition helps you judge distances and avoid hitting walls. The visual clarity is especially useful when building or mining in confined underground spaces.
