SCAN Shaders designed to create an oppressive atmosphere by severely limiting visibility. Instead of traditional lighting, the shader simulates a scanning device effect. Every two seconds, a horizontal update bar moves from top to bottom across the screen, briefly illuminating nearby surroundings before fading back into darkness.

Features:

Severely reduced overall visibility
Periodic scanning light effect every two seconds
Horizontal illumination bar moving from top to bottom
Brief environmental lighting during each scan cycle
Designed to create tension and limited spatial awareness
Experimental atmosphere-focused rendering
