I am trying to get a WebMapServiceTerrainProvider from Wayne working with Geoserver. I am using the demo sf:sfdem terrain to test out Cesium's rendering of it. Whenever I use the terrain provider I can see calls to get the imagery as well but nothing shows on the globe (I can see through it). When I remove the terrain provider the imagery base renders fine.
Is there any other way to render terrain from geoserver other than WebMapServiceTerrainProvider?
