◆ setEnableVpls()

inlineinherited

◆ setFadeAttenuationRange()

void Ogre::ForwardPlusBase::setFadeAttenuationRange ( bool  fade)
inlineinherited

Attenuates the light by the attenuation range, causing smooth endings when at the end of the light range instead of a sudden sharp termination.

This isn't physically based (light's range is infinite), but looks very well, and makes more intuitive to manipulate a light by controlling its range instead of controlling its radius.

See also
Light::setAttenuationBasedOnRadius and
setAttenuation. And even when controlling the light by its radius, you don't have to worry so much about the threshold's value being accurate. It has a tendency to make lights dimmer though. That's the price to pay for this optimization and having more intuitive controls. Enabled by default.

In math: atten *= max( (attenRange - fDistance) / attenRange, 0.0f );

◆ setFineLightMaskGranularity()

void Ogre::ForwardPlusBase::setFineLightMaskGranularity ( bool  useFineGranularity)
inlineinherited

Toggles whether light masks will be obeyed per object & per light by doing: if( movableObject->getLightMask() & light->getLightMask() ) doLighting( movableObject light ); Note this toggle only affects Forward+ lights.

You may want to see HlmsPbs::setFineLightMaskGranularity for control over Forward lights. If you only need coarse granularity control over Forward+ lights, you may get higher performance via CompositorPassSceneDef::mLightVisibilityMask (light_visibility_mask keyword in scripts).

◆ setHlmsPassProperties()

virtual void Ogre::Forward3D::setHlmsPassProperties ( Hlms hlms)
virtual

Reimplemented from Ogre::ForwardPlusBase.
