I'm just getting started with Cesium to see if the KML support will work for our project. I immediately ran into a problem when loading a kml file which contains a ground overlay; there appears to be a rectangle drawn in the correct position, but it is not rendering the tif image on the rectangle.
The tif image file is on the file system in the same directory as the KML file, and I've also tried putting a more complete path to the tif file with no improvement.
Resource interpreted as Image but transferred with MIME type image/tiff
I will attach the tif if I can.
Here is the kml:
<?xml version="1.0" encoding="UTF-8"?>
