I do not understand the meaning of this console var
REPGRAPH_DEVCVAR_SHIPCONST(int32, "Net.RepGraph.TrickleDistCullOnDormancyNodes", CVar_RepGraph_TrickleDistCullOnDormancyNodes, 1, "Actors in a dormancy node that are distance culled will trickle through as dormancy node empties");
when this console var enable, will call ConnectionActorInfo.SetCullDistanceSquared(0.f) to set culldistanceSquared to zero. why ? What is the purpose to set CullDistance to zero?
