Luminus Crepuscular – Screen Space God Rays

Turn sunlight into the signature of your scene.

Soft morning rays through a forest. Bold beams breaking through silhouettes. A warm glow that makes an ordinary environment feel alive. With Luminus Crepuscular, create lighting that draws the eye, sets the mood and gives your world a lasting visual identity.

Powered by compute shaders, Luminus Crepuscular brings customizable god rays and light shafts to Unity through a lightweight screen-space approach. Camera depth and radial sampling create striking sunlight effects without requiring a full volumetric lighting system—giving you expressive lighting with a rendering budget you can control.

• Shape the light. Own the atmosphere. Fine-tune color, intensity, ray length, density, decay and exposure. Build a delicate cinematic glow, dramatic shafts of sunlight or a bold stylized look that becomes part of your game’s identity.
• Bring your beams to life. Optional atmospheric dust adds animated detail and variation inside the light shafts. Visibility responds to the camera’s angle relative to the sun, making the atmosphere shift naturally as players explore your world.
• Put performance in your hands. Adjustable sample quality and render resolution let you balance visual richness against rendering cost. Choose the detail your scene deserves and the budget your project allows.
• Create across Unity’s render pipelines. Dedicated implementations for URP, HDRP and the Built-in Render Pipeline, with pipeline-specific sun controllers and straightforward setup, help you get from installation to shaping your lighting.
