The version numbers I use are:

```auto
"dependencies": {
    "@babylonjs/core": "^5.12.1",
    "@babylonjs/gui": "^5.12.1",
    "@babylonjs/loaders": "^5.12.1",

```

An attribute error occurred when I added a material to the ground, the code is as follows:

```auto
// Ground
     var ground = BABYLON.MeshBuilder.CreateGround("ground", { height: 50, width: 50, subdivisions: 4 }, scene);
     var groundMaterial = new BABYLON.StandardMaterial("groundMaterial", scene);
     groundMaterial.diffuseTexture = new BABYLON.Texture("textures/wood.jpg", scene);
     groundMaterial.diffuseTexture.uScale = 30;
     groundMaterial.diffuseTexture.vScale = 30;
     groundMaterial.specularColor = new BABYLON.Color3(.1, .1, .1);
     ground.material = groundMaterial;

```

What is the reason for this please?

@yjkhaoyun

It is a type error from typescript. uScale is not defined in BABYLON.BaseTexture, but in BABAYLON.Texture.

The problem is BABYLON.StandardMaterial has `diffuseTexture` defined as type BaseTexture in babylon.js source code. You can work around this typescript transpile time error with either:

```auto
const texture = new BABYLON.Texture("textures/wood.jpg", scene);
texture.uScale = 30;
texture.vScale = 30;
groundMaterial.diffuseTexture = texture;

```

or

```auto
groundMaterial.diffuseTexture = new BABYLON.Texture("textures/wood.jpg", scene);
(groundMaterial.diffuseTexture as BABYLON.Texture).uScale = 30;
(groundMaterial.diffuseTexture as BABYLON.Texture).vScale = 30;

```
