Description

Sets a Niagara StaticMesh parameter by name, overriding locally if necessary.

Set a constant in an emitter of a Niagara System void UNiagaraFunctionLibrary::SetUpdateScriptConstant(UNiagaraComponent* Component, FName EmitterName, FName ConstantName, FVector Value) { TArray> &Emitters = Component->GetSystemInstance()->GetEmitters();

for (TSharedPtr &Emitter : Emitters) { if(UNiagaraEmitter* PinnedProps = Emitter->GetProperties().Get()) { FName CurName = *PinnedProps->EmitterName; if (CurName == EmitterName) { Emitter->GetProperties()->UpdateScriptProps.ExternalConstants.SetOrAdd(FNiagaraTypeDefinition::GetVec4Def(), ConstantName, Value); break; } } } }
