## Batch Import PBR Textures

<div align="left"><figure><img src="/files/oJWpV7ifja5hlqvrf30c" alt=""><figcaption></figcaption></figure></div>

In the texture editing panel, click the "Import" button, you can select multiple PBR textures in the folder with one click to import them automatically.

{% hint style="info" %}
The PBR material system contains two sets of workflows : the metallic/roughness system and the specularity/glossiness system, which <mark style="background-color:purple;">D5 supports belongs to the metallic/roughness workflow</mark>.&#x20;

The texture imported by the user should **conform to the suffix naming rules of this workflow** in order to correctly identify the material effect.&#x20;

For more details, please refer to:[What is the correct naming convention when importing PBR maps with one click?](https://docs.d5render.com/user-guide/material/what-is-the-correct-naming-convention-when-importing-pbr-maps-with-one-click)
{% endhint %}

## Reset

Restores the material parameters to their initial state (the parameters that existed when the project file was just opened or when the material was assigned to the model surface).
