Blue texture for Cesium World Terrain - Why?

CesiumJS
1

I am a bit stuck with the terrain on my cesium scene. I am loading the world terrain (assetID 1) from cesium ion, and it is communicating correctly as far as I can tell in the network tab. I see cors pre-flight requests going out, and then I see the requests for the terrain texture data. I even get a reply back with what I believe is terrain texture data.

When i use googlePhotorealistic3DTiles it seems fine, but thats not the dataset I’d like to use.

Is there perhaps a better way to do this than this?

this.cesiumScene.globe = new Globe();
let defaultTerrain = new Terrain(CesiumTerrainProvider.fromIonAssetId(1));
this.cesiumScene.setTerrain(defaultTerrain);

I want to use the scene directly where I can, and don’t make a viewer for this. The viewer does too much for my simple need.

I am developing on localhost:8443, if that matters but I don’t think it would.

Does anyone have any pointers to help me out?

I have seen there a good many posts about this, and they seem to suggest network related issues, or quota limits but those seem fine to me.

     this.cesiumScene.globe = new Globe();
     let defaultTerrain = await createWorldTerrainAsync({
       requestVertexNormals: true, // This enables terrain lighting
       requestWaterMask: true, // This enables water effects if any
     });               
     this.cesiumScene.terrainProvider = defaultTerrain;

This also has the same behavior, except I see what looks to be water reflections on the blue surface, but still looks strange.

I managed to get the terrain and the imagery and the buildings all loaded now!

     this.cesiumScene.globe = new Globe();
     this.cesiumScene.terrainProvider = await createWorldTerrainAsync();
     this.cesiumScene.imageryLayers.addImageryProvider(
       await IonImageryProvider.fromAssetId(3),
     ); 
        
     try {
       //this.tileset = await createGooglePhotorealistic3DTileset();
       this.tileset = await createOsmBuildingsAsync();

I am using a scene only, and so the normal ways to set this with the viewer do not apply to me.

Whew! Glad that sorted out.

I believe the problem with my initial request was the way I was trying to assign the terrain/imagery. I now believe terrain is more about the shape of the land, and the imagery is actually what I needed to show.

Thanks for the forum! Hope this answers someone else’s questions about the blue earth.
