3D Lighting

Expert guidance for realistic 3D lighting with shadows and global illumination.

NEVER Do

NEVER use VoxelGI without setting a proper extents — Unbound VoxelGI tanks performance. Always set size to tightly fit your scene.
NEVER enable shadows on every light — Each shadow-casting light is expensive. Use shadows sparingly: 1-2 DirectionalLights, ~3-5 OmniLights max.
NEVER forget directional_shadow_mode — Default is ORTHOGONAL. For large outdoor scenes, use PARALLEL_4_SPLITS for better shadow quality at distance.
NEVER use LightmapGI for fully dynamic scenes — Lightmaps are baked. Moving geometry won't receive updated lighting. Use VoxelGI or SDFGI instead.
NEVER set omni_range too large — Light attenuation is quadratic. A range of 500 affects 785,000 sq units. Keep range as small as visually acceptable.
NEVER hide a Light node using the Visible property to exclude it from a Lightmap bake — Hiding a light has no effect on the baker. You must change the light's Bake Mode to Disabled.
NEVER use VoxelGI with paper-thin walls — VoxelGI evaluates lighting using a 3D grid. Thin walls (less than one voxel thick) will cause severe light leaking. Seal your geometry or place hidden thick MeshInstance3D blocks around the exterior.
NEVER leave shadow bias at default for cascades — Default bias often causes Peter Panning or light leaking at split transitions. Tune bias per-light based on your scene's scale.
NEVER bake LightmapGI without a Denoiser — Godot's baked lightmaps are noisy by default. Use OIDN or JNLM (in Project Settings) for professional results.
NEVER use real-time SDFGI on Mobile/Compatibility renderers — It is a Forward+ exclusive feature. Use fake GI bounce lights for lower-end platforms.
NEVER use 'Update Continuity' in ReflectionProbes for performance — Keep ReflectionProbes on 'Update Once' and trigger manual updates only when necessary.
NEVER overflow the clustered shadow atlas — WHY: Forward+ packs Omni/Spot shadows into a shared atlas. Too many shadowed positional lights → atlas thrash, flickering, or silent quality collapse. Cap shadowed Omni (~3–5) and Spot (~2–4); use light_lod_optimizer.gd / distance fade before raising atlas size.
NEVER stack dozens of overlapping shadowed Omni/Spot in one cluster cell — WHY: Clustered light iteration cost scales with overlapping lights per tile. Prefer non-shadowed fills, tighter omni_range/spot_range, and distance_fade_* so far lights leave the cluster.

DirectionalLight3D (Sun/Moon)

Shadow Cascades

# For outdoor scenes with camera moving from near to far
extends DirectionalLight3D

func _ready() -> void:
    shadow_enabled = true
    directional_shadow_mode = SHADOW_PARALLEL_4_SPLITS
    
    # Split distances (in meters from camera)
    directional_shadow_split_1 = 10.0   # First cascade: 0-10m
    directional_shadow_split_2 = 50.0   # Second: 10-50m
    directional_shadow_split_3 = 200.0  # Third: 50-200m
    # Fourth cascade: 200m - max shadow distance
    
    directional_shadow_max_distance = 500.0
    
    # Quality vs performance
    directional_shadow_blend_splits = true  # Smooth transitions

Day/Night Cycle

MANDATORY day_night_cycle.gd — do not re-inline sun energy/color recipes here.

OmniLight3D (Point Light)

Keep omni_range tight; prefer quadratic attenuation. Flicker/campfire loops belong in scene scripts — not this body. Shadowed Omni count is a hard budget (see NEVER).

SpotLight3D (Flashlight/Headlights)

MANDATORY spotlight_projector_setup.gd for range/angle/projector cookies and camera-follow flashlights. Do not paste Spot setup here.

Global Illumination (script-first)

Use the golden-path table above. Body decision only:

Path	Script	When
Indoor / sealed	MANDATORY `light_probe_manager.gd` (+ `lighting_manager.gd`)	Tight VoxelGI extents per room; never paper-thin walls
Outdoor Forward+	MANDATORY `sdfgi_probe_manager.gd`	Real-time GI; Do NOT Load on Mobile/Compatibility
Static / Mobile bake	MANDATORY `lightmap_bake_helper.gd`	LightmapGI + Shadowmasking; bake mode ≠ Visible hide
No GI budget	MANDATORY `fake_gi_bounce.gd`	Fill lights only

Do not re-inline VoxelGI/SDFGI/Lightmap property setup here.

Environment & Sky

Sky/ambient/tonemap transitions → MANDATORY environment_blender.gd. Volumetric fog / shafts → MANDATORY volumetric_fx.gd (+ volumetric_fog_zones.gd for caves/forests).

Do NOT Load these for pure light-budget / shadow-atlas / cascade tuning — stay on light_lod_optimizer.gd / shadow_cascade_tuner.gd.

ReflectionProbe

For localized reflections (mirrors, shiny floors):

# reflection_probe.gd
extends ReflectionProbe

func _ready() -> void:
    # Capture area
    size = Vector3(10, 5, 10)
    
    # Quality
    resolution = ReflectionProbe.RESOLUTION_512
    
    # Update mode
    update_mode = ReflectionProbe.UPDATE_ONCE  # Bake once
    # or UPDATE_ALWAYS for dynamic reflections (expensive)

Performance Optimization

Light Budgets

# Recommended limits:
# - DirectionalLight3D with shadows: 1-2
# - OmniLight3D with shadows: 3-5
# - SpotLight3D with shadows: 2-4
# - OmniLight3D without shadows: 20-30
# - SpotLight3D without shadows: 15-20

# Disable shadows on minor lights
@onready var candle_lights: Array = [$Candle1, $Candle2, $Candle3]

func _ready() -> void:
    for light in candle_lights:
        light.shadow_enabled = false  # Save performance

Per-Light Shadow Distance

# Disable shadows for distant lights
extends OmniLight3D

@export var shadow_max_distance := 50.0

func _process(delta: float) -> void:
    var camera := get_viewport().get_camera_3d()
    if camera:
        var dist := global_position.distance_to(camera.global_position)
        shadow_enabled = (dist < shadow_max_distance)

Edge Cases

Shadows Through Floors

# Problem: Thin floors let shadows through
# Solution: Increase shadow bias

extends DirectionalLight3D

func _ready() -> void:
    shadow_enabled = true
    shadow_bias = 0.1  # Increase if shadows bleed through
    shadow_normal_bias = 2.0

Light Leaking in Indoor Scenes

# Problem: VoxelGI light bleeds through walls
# Solution: Place VoxelGI nodes per-room, don't overlap

# Also: Ensure walls have proper thickness (not paper-thin)
