<div>Sorry, I'm getting a little confused. Are you generating ground overlay layers (eg one raster output for a number of layers) or actual KML features (eg, Placemarks with a geometry and an style marker)?</div>
<div><br>
</div>
<div>If you are posting the KML to google maps, then the KML is public. Can you post the link to the KML so the list can actually see it and see what might be wrong. As for why your lidar layer might be blank, remember that KML output is always in epsg:4326.
Perhaps you don't have a projection defined for your lidar layer and do for others.</div>
