Duplicate texture maps are set in cesium but have no effect

CesiumJS

Hello everyone, I created a custom geometry in cesium, set up a map. After the UV coordinates of the map are changed, I set the map to tile and repeat. Cesium.TextureWrap.REPEAT But it can’t be repeated now. This is my code. Can I help you?
Cesium.Resource.createIfNeeded(imageUrl).fetchImage().then(function (image) {

                var vtxfTexture;

                var context = self.viewer.scene.context;

                

                if (Cesium.defined(image.internalFormat)) {

                    vtxfTexture = new Cesium.Texture({

                        context: context,

                        pixelFormat: image.internalFormat,

                        width: image.width,

                        height: image.height,

                        source: {

                            arrayBufferView: image.bufferView

                        }

                    });

                } else {

                    vtxfTexture = new Cesium.Texture({

                        context: context,

                        source: image

                    });

                }

                // image.onload = function () {

                    

                // };

                vtxfTexture._sampler =new Cesium.Sampler({wrapS:Cesium.TextureWrap.REPEAT,wrapT:Cesium.TextureWrap.REPEAT});

                // context.defaultTexture._sampler =new Cesium.Sampler({});

                texture = vtxfTexture;

            });

This looks correct to me at first glance. @weiyinggh would you be able to put together a complete Sandcastle code example I can run to show how you’re testing this? You can create your example and then click “Share” and paste the link here:
