Preserving Vanilla Lighting and Block Textures

Confirming Vanilla Visuals

Unlike traditional shader packs that overhaul lighting engines, tint skies, and add artificial bloom, Cosinus deliberately maintains the simple look of vanilla blocks and standard lighting. It adds its strange twists purely through mathematical screen transformations.

Verifying Correct Appearance

To make sure the shader is rendering as intended:

1. Place a light source, such as a torch or lantern, inside a dark cave. Notice that the illumination follows standard vanilla light levels and falloff without realistic volumetric lighting or heavy shadows.

2. Inspect nearby structures and textures. Blocks retain their original vanilla colors and textures rather than being modified with custom reflective or bumpy surface effects.

3. Look across the horizon. You should see the classic block textures and lighting intact, but the entire scene will twist into unusual, wavy contours. This balance allows you to experience a weird visual novelty without losing the clarity of vanilla gameplay.
