Lumi is a professional light detection solution that can be used to sample light luminance and color, enhancing a variety of gameplay scenarios, such as:

• Visibility mechanics for stealth and horror games.
• Simulating sunlight input for solar panels and plants.
• Checking exposure to direct sunlight for characters like vampires.

Let your imagination guide you as Lumi lights the way!

Features

• Supports URP, BIRP, and HDRP pipelines.
• Supports Directional, Point, and Spot Lights, using raycasting for occlusion detection.
• Supports light cookies.
• Sample light at multiple points and average results for precise detection.
• Baked light sampling via Light Probes and Lightmaps.
• Sample luminance, lightness, and color, using custom curves for fine tuning.
• Alpha clipping support correctly factors in shadows from cutout materials.
• Transparent material shadow support (Built-in Render Pipeline only).
• Directional sampling mode: Essential for systems where light angle matters—perfect for simulating solar panels.
• Editor integration: Runs seamlessly in the editor for rapid development.
• Accounts for human brightness perception to ensure sampled luminance matches user expectations.
• Can be used with fake lights, such as the FakeLight asset.

Technical Details:

• Realtime lights rely on physics raycasts to detect occlusion.
• Does not account for screenspace effects, such as ambient occlusion or global illumination.
• Does not support Adaptive Probe Volumes (APV).
