NB: dynamic objetcs don't need it because already done in traverseHRC()
|
|
(but don't worry, reset state is flagged, so resetLighting() no op...)
|
|
This is important only for static object (freezeHRC()).
|
|
Why? because we are not sure the MergedPointLight does not represent moving DynamicPointLights.
|
|
Actually, it surely does. Because most of the static light setup return<=2 lights, and MaxLightContribution
|
|
is typically==3. So any additional light may surely be a dynamic one.
|
|
NB: this may not be useful since dynamicLights resetLighting() of all models in range. But this is important
|
|
when the dynamic light leave the model quiclky! (because don't dirt the model).
|
|
NB: this is also useful only if there is no dynamic light but the ones merged in MergedPointLight.
|
|
Because dynamic always reset their old attached models (see below). This still can arise if for example
|
|
_MaxLightContribution=2 and there is a FrozenStaticLightSetup of 2 lights....
