Error displaying when setting polygonGeometry object water material.

[LaogaKAKA]

Set the "appearance" attribute on the Primitive, and when the geometry object is PolygonGeometry, it displays an issue, as follows:

Would you be able to include a Sandcastle example that replicates the issue? That would help us give us more context to determine the issue. Thanks!

@ggetz Hi, you can reproduce in here. This issue seems to occur since v1.110.

const viewer = new Cesium.Viewer("cesiumContainer");

const positions = [ Cesium.Cartesian3.fromDegrees(115.98, 22.99, 0.8), Cesium.Cartesian3.fromDegrees(115.99, 22.995, 0.8), Cesium.Cartesian3.fromDegrees(115.995, 22.98, 0.8), Cesium.Cartesian3.fromDegrees(115.98, 22.98, 0.8) ];

const material = new Cesium.Material({ fabric: { type: Cesium.Material.WaterType, uniforms: { baseWaterColor: Cesium.Color.AQUA.withAlpha(0.3), normalMap: Cesium.buildModuleUrl( "Assets/Textures/waterNormals.jpg" ), frequency: 1000, animationSpeed: 0.01, amplitude: 10, specularIntensity: 5 } } });

let hierarchy = new Cesium.PolygonHierarchy( positions,

);

let polygonGeometry = new Cesium.PolygonGeometry({ polygonHierarchy: hierarchy, textureCoordinates: { positions:[ new Cesium.Cartesian2(0, 1), new Cesium.Cartesian2(0, 0), new Cesium.Cartesian2(1, 0), new Cesium.Cartesian2(0, 0), ] }})

const water = new Cesium.Primitive({ show: true, geometryInstances: new Cesium.GeometryInstance({ geometry:polygonGeometry }), appearance: new Cesium.EllipsoidSurfaceAppearance({ material, aboveGround: true }) });

viewer.scene.primitives.add(water);

viewer.camera.flyTo({ destination: Cesium.Cartesian3.fromDegrees(115.985, 22.985, 2000), duration: 0 });

@qmhc 这个你用GroundPrimitive就没这个UV问题了，或者增加textureCoordinates

It's been so long, I didn't expect anyone to come back. Haha, I solved it with Shader, but thank you all! ; )

朋友，如果我的primitive顶点是动态添加的，那应该怎么确定textureCoordinates呢，或者使用GroundPrimitive的时候怎么解决附着在3dTiles上 的问题呢
