void	dumpObjectInfo () const
	Dumps information about signal connections, etc.
bool	setProperty (const char *name, const QVariant &value)
	Sets the value of the object's name property to value.
bool	setProperty (const char *name, QVariant &&value)
QVariant	property (const char *name) const
	Returns the value of the object's name property.

QT_BEGIN_NAMESPACE bool QQuick3DBakedLightmap::isEnabled ( ) const

\qmltype BakedLightmap \inherits QtObject \inqmlmodule QtQuick3D

Specifies baked lightmap settings for a model.

Since: 6.4

A BakedLightmap object can be used to enable:

\list

persistently storing the baked lightmap data - during baking, or
loading the previously generated and stored lightmaps - at run time. \endlist

A Model with \l{Model::usedInBakedLighting}{usedInBakedLighting} set to true is considered to be part of the raytraced scene when baking lightmaps, meaning the model's geometry and material contribute to direct and indirect lighting. This on its own does not however enable generating, including full calculation of bounced indirect lighting, and finally saving a lightmap for the model. To do that, the model also needs to be associated with an \l enabled BakedLightmap object with a unique key set.

When running in normal mode, the same BakedLightmap object indicates that the Model has lightmap data, and that the engine should attempt to load this data (based on the unique key) and use it when rendering.

For more information on how to bake lightmaps, see the \l Lightmapper documentation.

Note: As of Qt 6.4, lightmap baking is in an early technical preview state. Changes to features, quality, and API are likely happen in future releases.

See also: Lightmapper, Model::usedInBakedLighting

\qmlproperty bool BakedLightmap::enabled

When false, the lightmap generated for the model is not stored during lightmap baking, even though \l key is set to a non-empty value.

The default value is true.

\qmlproperty string BakedLightmap::key

When non-empty and \l enabled is true, the lightmap generated for the model is stored persistently during lightmap baking. No other Model in the scene must use the same key.

The default value is empty.

\qmlproperty string BakedLightmap::loadPrefix

Deprecated: [6.10] This has no effect. See \l Lightmapper documentation.
