spotLight is undoable, queryable, and editable.

TlightCmd is the base class for other light commands. TnonAmbientLightCmd is a class that looks like a command but is not. It is a base class for the extended/nonExtended lights. TnonExtendedLightCmd is a base class and not a real command. It is inherited by several lights: TpointLight, TdirectionalLight, TspotLight etc. The spotLight command is used to edit the parameters of existing spotLights, or to create new ones. The default behaviour is to create a new spotlight.

Return value

stringLight shape name boolean Barn door enabled state angle Left barn door angle angle Right barn door angle angle Top barn door angle angle Bottom barn door angle angle Cone angle angle Penumbra angle float Dropoff value
double[]when querying the rgb or shadowColor flags double when querying the intensity flag boolean when querying the useRayTraceShadows or exclusive flags linear[] when querying the position flag angle[] when querying the rotation flag string when querying the name flag
intrate of light decay, when querying the decayRate flag
intNumber of shadow samples, when querying the shadowSamples flag boolean True if soft shadows are enabled, when querying the softShadow flag float Shadow dithering value, when querying the shadowDither flag float Disc radius value, when querying the discRadius flag

In query mode, return type is based on queried flag.

MEL examples

// Create a spot light
string $light = `spotLight -coneAngle 45`;

// Change the cone angle value
spotLight -e -coneAngle 33 $light;

// Query it
spotLight -q -coneAngle $light;
// Result:33//
