Lightmass Importance volume

Hi guys.

Is there a way to set my brush size for a lightmass importance volume in C++?

I have searched for this but can not find anything about setting any attributes for lightmass importance volumes.

Thank you in advance.

My code:

.h:

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include “Lightmass/LightmassImportanceVolume.h”
#include “Level1LightmassImportanceVolume.generated.h”

/**
*
*/
UCLASS()
class CHAIN_JUMPER_API ALevel1LightmassImportanceVolume : public ALightmassImportanceVolume
{
GENERATED_BODY()

public:

ALevel1LightmassImportanceVolume();

};

cpp:

// Fill out your copyright notice in the Description page of Project Settings.

#include “Chain_Jumper.h”
#include “Level1LightmassImportanceVolume.h”

ALevel1LightmassImportanceVolume::ALevel1LightmassImportanceVolume() {

}
