Luminus Crepuscular – Screen Space God Rays

• Render pipelines: URP, HDRP and Built-in Render Pipeline
• Rendering technique: screen-space radial light accumulation using camera depth
• URP integration: Scriptable Renderer Feature
• HDRP integration: Custom Pass Volume
• Built-in integration: camera image effect
• Ray sample options: 8, 12, 30, 60 and 100 samples
• Adjustable ray color, intensity, length/density, decay, weight and exposure
• Adjustable maximum ray distance
• Optional sun visibility/off-screen culling controls
• Dedicated sun controller for each render pipeline
• HDRP support for Physically Based Sky interaction and lux-based directional light intensity
• HDRP Full / Half / Quarter ray-resolution options
• Optional animated atmospheric dust
• Adjustable dust strength, scale, movement, density and light-angle response
• Depth-based scene occlusion
• Scene View support
• Designed to work with a standard Directional Light
• No full volumetric ray marching required
• Performance can be scaled through resolution, sample count and optional dust rendering

Note: Luminus Crepuscular is a screen-space effect. Objects outside the camera view cannot contribute to ray occlusion in the same way as a fully volumetric lighting solution.

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.
