+00080                 NB: dynamic objetcs don't need it because already done in traverseHRC() 
+00081                 (but don't worry, reset state is flagged, so resetLighting() no op...)
+00082                 This is important only for static object (freezeHRC()).
+00083                 Why? because we are not sure the MergedPointLight does not represent moving DynamicPointLights.
+00084                 Actually, it surely does. Because most of the static light setup return<=2 lights, and MaxLightContribution 
+00085                 is typically==3. So any additional light may surely be a dynamic one.
+00086                 NB: this may not be usefull since dynamicLights resetLighting() of all models in range. But this is important
+00087                 when the dynamic light leave the model quiclky! (because don't dirt the model).
+00088                 NB: this is also usefull only if there is no dynamic light but the ones merged in MergedPointLight. 
+00089                 Because dynamic always reset their old attached models (see below). This still can arise if for example 
+00090                 _MaxLightContribution=2 and there is a FrozenStaticLightSetup of 2 lights....
