I have been trying to use tiff images in my cesium app, but nothing seems to be working. I started by using the example tiff image provided of the Courtyard and I upload it to Cesium Ion, but then the sample code I get doesn’t work (i get error). And even when I run it on Cesium SandCastle (from the option shown below), it doesn’t work (get errors again). All the steps I have been following are from the docs itself. There’s a similar question posted just yesterday here.
