SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides expert guidance and practical code examples for implementing realistic and performant 3D lighting in Godot Engine, addressing common challenges with shadows, global illumination, and light types.

Core Features & Use Cases

DirectionalLight3D: Optimize shadow cascades and implement day/night cycles.
OmniLight3D & SpotLight3D: Tune attenuation, range, and create effects like flickering or projectors.
Global Illumination: Choose between VoxelGI and SDFGI, and configure LightmapGI for baked lighting.
Environment & Sky: Set up HDR skyboxes and volumetric fog.
Performance: Learn light budgets and per-light shadow distance optimization.
Use Case: You're developing an outdoor scene in Godot and need to implement a realistic sun with dynamic shadows that don't tank performance. This Skill provides the exact GDScript code and configuration settings for DirectionalLight3D shadow cascades and a day/night cycle.

Quick Start

Use the godot-3d-lighting skill to configure DirectionalLight3D shadow cascades for an outdoor scene.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I optimize DirectionalLight3D shadow cascades in Godot for an outdoor scene?▼

To optimize DirectionalLight3D shadow cascades in Godot, you adjust shadow distance settings and utilize per-light shadow distance parameters. This ensures realistic dynamic shadows without tanking performance in large outdoor scenes.

What is the best way to configure global illumination in Godot using VoxelGI or SDFGI?▼

Configuring global illumination in Godot involves choosing between VoxelGI for dynamic scenes or SDFGI for open-world environments. This Skill provides expert patterns to set up either GI technique for realistic light bouncing.

How do I bake static lighting with LightmapGI in Godot?▼

To bake static lighting with LightmapGI in Godot, you configure light probes and bake the lighting data into textures. This approach improves performance by precomputing global illumination for non-dynamic objects.

Can I create a day/night cycle and volumetric fog effects using GDScript in Godot?▼

You can create dynamic day/night cycles and volumetric fog effects in Godot using GDScript. This Skill provides code patterns to manipulate DirectionalLight3D properties and environment settings for atmospheric effects.

Why does my Godot 3D lighting performance drop when using multiple OmniLight3D and SpotLight3D shadows?▼

Godot 3D lighting performance drops with multiple shadows due to high light budgets and unoptimized shadow distances. You can resolve this by tuning OmniLight3D attenuation and per-light shadow distance limits.
