Luxium Let There Be Light Mod brings custom lighting, soft shadows, and clean fog to low-end computers without slowing down your game. It reworks how the world renders by talking directly to Sodium or Embeddium. Players on weak laptops and integrated graphics chips can now enjoy pretty scenery while keeping their frame rates high.

Features:
- Built-In Lighting and Shadows: Adds sun shadows, custom light, and ambient fog across the Overworld.
- Direct Rendering Engine: Works directly alongside Embeddium or Sodium instead of running heavy shader packs through Iris or Oculus.
- Luxium Spatial Resolution: Renders world blocks at a lower target and sharpens the image on screen while keeping your hand and user interface crisp.
- Temporal Frame Reprojection: Generates extra frames between real frames to increase frame counts by twenty to thirty FPS.
- Opaque Ice Setting: Moves ice blocks to the solid render layer to stop lag on budget computers.
- Saves system power by skipping unneeded frame work and sharing visual data between active effects.
- Maintains smooth gameplay on basic integrated hardware like Intel UHD graphics chips.
