# Default

There are situations, when configuring a product, not all parts can be customized, in other words some parts of a 3D model may have a material that cannot be changed. Let's take a sofa configurator, we might have some materials within the 3D sofa model that are permanent or by default. For example, the sofa "legs" material is only one and will load by default.

Setting default materials its easy, go at the upper right side of the screen and select 'Default' from the drop-down button and click '**Add block**.

After clicking "Add block", the edit page for "Default" will open.

You will be able to name the block in the **Title** field and add variants from the "**Add Variant**" button in the lower right screen. Once you click 'Add Variant' a popup window shows up:

In the popup window we select the 3D model, the parts (in our case the legs) and material (wood) and click 'Save'. Once you click 'Save', it will create the first 'default' material and you can repeat this process for other parts if necessary.&#x20;

Click "Save" again and it will create your "default" block, from now on every time the sofa configurator is loaded the legs will have wood material applied by default. Now click on the blue "**Preview**" button at the top right of the screen and see how it looks:

{% hint style="warning" %}
**Applying default materials to a 3D object/part and then material option sets to the same object/part will not work. Remove the default material first, then apply the material option set.**
{% endhint %}
