loading complicated kml with sub-kml ?

Hi everyone!

I use:

var dataSource1= new Cesium.KmlDataSource();
dataSource1.load('filename.kmz');
viewer.dataSources.add(dataSource1);

to load .kml. I came up to one kml with nodes of other kml-a which looks like this:

<kml xmlns="http://earth.google.com/kml/2.2">
  <Document>
    <name>Name</name>
       <NetworkLink>
          <name>SUB_KML_0_0</name>
                   <Region>
                      <LatLonAltBox>
                         <north>1.0000</north>
                         <south>2.0000</south>
                         <east>1.0000</east>
                         <west>2.0000</west>
                      </LatLonAltBox>
                      <Lod>
                        <minLodPixels>7000</minLodPixels>
                        <maxLodPixels>-1</maxLodPixels>
                      </Lod>
                   </Region>
                   
       <Link>
          <href>http://server_name/sub_kml_0_0.kmz</href>
          <viewRefreshMode>onRegion</viewRefreshMode>
       </Link>

      </NetworkLink>
       <NetworkLink>
          <name>SUB_KML_0_1</name>
                   <Region>
                      <LatLonAltBox>
                         <north>2.0000</north>
                         <south>3.0000</south>
                         <east>1.0000</east>
                         <west>2.0000</west>
                      </LatLonAltBox>
                      <Lod>
                        <minLodPixels>7000</minLodPixels>
                        <maxLodPixels>-1</maxLodPixels>
                      </Lod>
                   </Region>
                   
       <Link>
          <href>http://server_name/sub_kml_0_1.kmz</href>
          <viewRefreshMode>onRegion</viewRefreshMode>
       </Link>

Q: Is it possible to load somehow in Cesium this kind of .kml or i have to generate one big kml which includes all "sub-kml" files into and load this big kml instead?

Thank you in front!!!

Hello,

Network links are not currently supported in Cesium, but it is in our roadmap for improved KML support in the future.

Best,
