\qmltype Light \inherits Node \inqmlmodule QtQuick3D

An uncreatable abstract base type for all lights.

Light itself is an uncreatable base for all of its subtypes. The subtypes provide multiple options to determine the style of the light.

For usage examples, see \l{Qt Quick 3D - Lights Example}.

See also

DirectionalLight, PointLight

\qmlproperty color Light::color This property defines the color applied to models illuminated by this light. The default value is white, rgb(255, 255, 255).

\qmlproperty color Light::ambientColor The property defines the ambient color applied to materials before being lit by this light. The default value is black, rgb(0, 0, 0).

\qmlproperty real Light::brightness This property defines an overall multiplier for this light’s effects. The default value is 1.

\qmlproperty Node Light::scope

The property allows the selection of a Node in the scene. Only that node and its children are affected by this light. By default the value is null, which indicates no scope selected.

Note

Scoped lights cannot cast real-time shadows, meaning a Light with a scope set should not set \l castsShadow to true. They can however generate baked shadows when \l bakeMode is set to Light.BakeModeAll.

\qmlproperty bool Light::castsShadow

When this property is enabled, the light will cast (real-time) shadows. The default value is false.

Note

When \l bakeMode is set to Light.BakeModeAll, this property has no effect. A fully baked light always has baked shadows, but it will never participate in real-time shadow mapping.

\qmlproperty real Light::shadowBias This property is used to tweak the shadowing effect when objects are casting shadows on themselves. The value range is [-1.0, 1.0]. Generally, a value inside [-0.1, 0.1] is sufficient. The default value is 0.

\qmlproperty real Light::shadowFactor This property determines how dark the cast shadows should be. The value range is [0, 100], where 0 means no shadows and 100 means the light is fully shadowed. The default value is 5.

\qmlproperty enumeration Light::shadowMapQuality The property sets the quality of the shadow map created for shadow rendering. Lower quality uses less resources, but produces lower quality shadows while higher quality uses more resources, but produces better quality shadows.

Supported quality values are: \value Light.ShadowMapQualityLow Render shadowmap using 256x256 texture. \value Light.ShadowMapQualityMedium Render shadowmap using 512x512 texture. \value Light.ShadowMapQualityHigh Render shadowmap using 1024x1024 texture. \value Light.ShadowMapQualityVeryHigh Render shadowmap using 2048x2048 texture.

The default value is Light.ShadowMapQualityLow

\qmlproperty real Light::shadowMapFar The property determines the maximum distance for the shadow map. Smaller values improve the precision and effects of the map. The default value is 5000. Unit is points in local coordinate space.

\qmlproperty real Light::shadowFilter This property sets how much blur is applied to the shadows. The default value is 5.

\qmlproperty enumeration Light::bakeMode The property controls if the light is active in baked lighting, such as when generating lightmaps.

\value Light.BakeModeDisabled The light is not used in baked lighting.

\value Light.BakeModeIndirect Indirect lighting contribution (for global illumination) is baked for this light. Direct lighting (diffuse, specular, real-time shadow mapping) is calculated normally for the light at run time. At run time, when not in baking mode, the renderer will attempt to sample the lightmap to get the indirect lighting data and combine that with the results of the real-time calculations.

\value Light.BakeModeAll Both direct (diffuse, shadow) and indirect lighting is baked for this light. The light will not have a specular contribution and will not generate realtime shadow maps, but it will always have baked shadows. At run time, when not in baking mode, the renderer will attempt to sample the lightmap in place of the standard, real-time calculations for diffuse lighting and shadow mapping.

The default value is Light.BakeModeDisabled

Note

Just as with \l Model::usedInBakedLighting, designers and developers must always evaluate on a per-light basis if the light is suitable to take part in baked lighting.

Warning

Lights with dynamically changing properties, for example, animated position, rotation, or other properties, are not suitable for participating in baked lighting.

This property is relevant both when baking and when using lightmaps. A consistent state between the baking run and the subsequent runs that use the generated data is essential. Changing to a different value will not change the previously generated and persistently stored data in the lightmaps, the engine's rendering behavior will however follow the property's current value.

For more information on how to bake lightmaps, see the \l {Lightmaps and Global Illumination}.
