Rex Shaders

Rex Shaders is a lightweight shader pack that brings a warm, nostalgic look to Minecraft without destroying your FPS. Soft sunlight, reflective water and gentle atmospheric haze, built to run smoothly even on mid-range hardware.

Features

• Soft shadows with adjustable quality and softness
• Reflective water with animated waves, sky reflections, sun glare and screen-space reflections
• Dynamic sky with warm sunrises and sunsets and deep blue nights
• Atmospheric fog that thickens during rain
• Waving plants: leaves, grass, flowers and crops sway in the wind
• Glowing light sources like lava, lanterns, glowstone and froglights, with a soft bloom effect
• Underwater, lava and powder snow fog
• Custom Nether and End lighting (shadows are disabled there for extra FPS)
• Optional depth of field for cinematic screenshots

Performance Presets

Preset	Best for
Low	Laptops and integrated graphics
Medium (default)	Most systems, balanced quality and FPS
High	Dedicated graphics cards
Ultra	High-end PCs and screenshots (DOF enabled)

Every effect can be tweaked in-game: shadow quality, shadow distance, sun angle, water transparency, wave speed, fog density, bloom, saturation and more.

Tip: If you need more FPS, lower Shadow Quality, Shadow Distance or turn off Water Reflections first.
