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.
