Runtime created Cesium Tileset with material (OSM Buildings for example) doesn't render

Cesium for Unreal
3

Thank you, here is the C++ snippet

	ACesium3DTileset* Tileset = Cast<ACesium3DTileset>(
		UGameplayStatics::BeginDeferredActorSpawnFromClass(GetWorld(), ACesium3DTileset::StaticClass(), FTransform()));
	if (Tileset)
	{
		Tileset->SetTilesetSource(ETilesetSource::FromCesiumIon);
		Tileset->SetIonAssetID(Id);
		Tileset->SetIonAccessToken(CesiumAccessToken);
		Tileset->Rename(*LayerNameTextBox->GetText().ToString().TrimStartAndEnd());

		TileSet->SetMaterial(BaseMaterial);
		TileSet->EnableFrustumCulling = false;
		TileSet->EnableFogCulling = false;
		TileSet->GetRootComponent()->SetMobility(EComponentMobility::Movable);
		UGameplayStatics::FinishSpawningActor(Tileset, FTransform());
       }
