How to render polygons with an animated water texture?

[mapper99]

Ah, this is not supported for entities:

Add Shader (Fabric?) to Entity

I have no idea what I'm doing wrong here var f= viewer.entities.add({     name: ...,     id: i,     position: new Cesium.SampledPositionProperty(),     orientation: new Cesium.SampledProperty(Cesium.Quaternion),     model: {         uri: ...,         scale: 1,         minimumPixelSize: 42,         defer: false,     }, });   f.model.material= new Cesium.Material({   fabric : {     type : 'Color',     uniforms : {       color : new Cesium.Color(1.0, 0.0, 0.0, 0.5)     }   }   }…

Which is sad
