# Nested smart object

> Customer's Canvas supports nested smart objects. They allow you to show only a part of a design in a cylindrical forms.

Mockups can represent volumetric products like mugs, cups, bottles, and so on. In such mockups, your customers can only see part of your design on the visible surface of a product. The other parts of your design are outside the visible area, so you need to hide them. These mockups contain a *nested smart object*. Such a smart object crops a part of your design that will be invisible.

These mockups contain a *nested smart object*. Such a smart object crops a part of your design that will be invisible.

For an example of such products, see the [Mug](https://customerscanvas.com/demos/mug-pim/) in our [Demos](https://customerscanvas.com/demos).

In this article, you will learn how to create a mockup that displays only a part of your design with cylindrical distortion.

Let's create a mockup for a mug that might look like this.

## Creating a new file

To create a mockup in Photoshop, select **File** > **New**. When a new dialog box opens, fill in the following fields:

* **Width** and **Height**. For this mug, the size is `1000px * 1000px`. The measurement units are pixels. To read more about sizes, see the [dimensions](./#dimensions) article.

* **Resolution**. Set to `72` DPI.

* **Color mode**. Select `RGB Color`.

* In the **Background Contents** drop-down box, select `White`.

## Rasterizing the layer

Now your file has only the `Background` layer. To create a regular layer, right-click this layer and select **Layer from Background**. In a new dialog box, insert a new name, for example, `Background`.

Now the layer is rasterized, you can add new layers and place some artwork.

## Adding substrates and overlayers

Let's add a substrate and overlay layers. To embed them, click **File** > **Embedding** or just drag and drop them.

In this case, there is a background, shadows, and the body of a mug.

## Smart Object

In this mockup, a smart object has a nested smart object within it. Let's create these smart objects.

1. Create a new rectangle with the **Rectangle** tool. The color is `white`.

2. Match the aspect ratio of this rectangle to the aspect ratio of your supposed design. The exact size doesn't matter.

3. Rename this layer to `Template`.

4. Right-click this layer and select **Convert to Smart Object**.

5. Rename this layer to `Design`.

6. Double-click the thumbnail of this layer, and this rectangle will be open in a new tab.

7. Right-click the layer and select **Convert to Smart Object**. Then, rename the layer to `Image`.

8. Select the area of this rectangle that will be visible on the cylindrical form. To do so, use the **Crop** tool. You can select the exact visible area. Then, save the result with Ctrl + S. In this example, the mockup displays the left side of a supposed design.

![Crop the nested smrt object.](images/nested-smart-object-crop.png)

The structure of the nested smart object is `Design` > `Image` > `Template`. 

10. Go back to the mockup file. Now you need to adjust the rectangle on the visible surface on the mug. For this, use **Edit** > **Transform** > **Warp**.

You may have different types of products, so you can use distort, perspective, etc.

11. Place this layer in the proper order.

:::note
Follow these instructions in the specified order only. Otherwise, your mockup won't represent your design image correctly in Customer's Canvas.

## Testing a design 

You may show how your design will look on a surface in perspective. To do so, double-click the `Image` smart object and place the design inside the `Image` smart object. 

This smart object contains only the `Template` layer. Embed your own design or create a temporary layer over the `Template` layer. The `Template` layer is white. You don't need to manipulate this layer.

Now you can see your design on your mockup. You can correct your smart objects to display your design properly.

![A mockup with a design.](images/nested-smart-object-with-design.png) 

After all these manipulations, don't forget to remove your design inside the `Image` smart object. In this smart object, there is only the Template layer. The structure of the smart object is `Design` > `Image` > `Template`.

## Saving the mockup

To save the product, click Ctrl + S or click **File** > **Save** and select the PSD format.

## Uploading a mockup

To upload a mockup to the Customer's Canvas cloud, read the [Add new assets](https://customerscanvas.com/docs/hub/admin-guide/manage-assets/file-manager.md#add-new-assets) topic.

## Connecting a mockup to a product
