void SceneUtil::LightManager::setLightingMask

(

unsigned int

mask

)

Parameters

mask	This mask is compared with the current Camera's cull mask to determine if lighting is desired. By default, it's ~0u i.e. always on. If you have some views that do not require lighting, then set the Camera's cull mask to not include the lightingMask for a much faster cull and rendering.

Here is the caller graph for this function:

void SceneUtil::LightManager::setStartLight

(

int

start

)

Set the first light index that should be used by this manager, typically the number of directional lights in the scene.

Here is the caller graph for this function:

void SceneUtil::LightManager::update

(

)

Internal use only, called automatically by the LightManager's UpdateCallback.
