Hi,
Do you mean the base color input of the PBR material? If so, then you can do something like this:
```
var myObj = app.scene.getObjectByName('myObject');
var mat = myObj.material;
new v3d.TextureLoader().load('myTexture.jpg', function(tex) { 
    mat.map = tex;
    mat.needsUpdate = true;
});
```
The ‘app’ variable in this snippet is the application instance which is usually available in an application’s stock js file if it was created with the Verge3D App Manager.

Hi Ivan,
Thanks for your replied, after do the some testing and researching I finally figure it up how to change the texture of PBR material, thanks for have a chance to learning and enlightened me. And there’s one question haven’t resolve yet that is how should I do with puzzle or js file to achieve the following function:
Upload image from HTML and rename it to myTexture.jpg

very appreciate

Hi,
I don’t think this is doable with Puzzles at the moment, but you can write a script with the help of the File/FileReader API.

First, add an input field of type “file” into the HTML file, for example inside the <body> element:
```
<body>
    ...
    <input type="file" id="loadImage" style="position: relative;" accept="image/x-png,image/jpeg"/>
</body>
```
Then, add the following snippet in your js file:
```
var myObj = app.scene.getObjectByName('Cube');
var mat = myObj.material;

document.getElementById('loadImage').addEventListener('change', function(e) {
    if (e.target.files.length) {
        var reader = new FileReader();
        reader.onload = function(e) {
            new v3d.TextureLoader().load(e.target.result, function(tex) {
                mat.map = tex;
                mat.needsUpdate = true;
            });
        }
        reader.readAsDataURL(e.target.files[0]);
    }
});
```
– this snippet only loads an image in the browser, but if you need to store it on a server you should also send a request with the image data and properly process it on the server-side, which needs additional coding / server setup.
