**What is HDRI?**

HDRI stands for High Dynamic Range imaging. HDRI images capture a wider range of light values than traditional images, which allows you to create more realistic lighting effects. HDRI images are typically used in 3D rendering and video games to create realistic lighting and shadows.

**How to import HDRI images into Unity**

To import an HDRI image into Unity, you can use the **Assets** > **Import Package** > **Custom Package** menu option. This will open the **Import Package** dialog box. In the **Package Folder** field, navigate to the folder where your HDRI image is located. Then, select the **HDRI** file and click the **Import** button.

**How to use HDRI images to create realistic lighting effects**

Once you have imported your HDRI image into Unity, you can use it to create realistic lighting effects. To do this, you will need to create a **Skybox** object and assign your HDRI image to it.

To create a Skybox object, you can use the **GameObject** > **3D Object** > Skybox menu option. This will create a new Skybox object in your scene.

To assign your HDRI image to the Skybox object, you can use the Inspector window. In the Inspector window, locate the Skybox property and click the … button. This will open the Select Skybox dialog box. In the Select Skybox dialog box, select your HDRI image and click the OK button.

Now that you have assigned your HDRI image to the Skybox object, you can see the HDRI image in your scene. The HDRI image will be used to create the background of your scene and to provide realistic lighting effects.

How to use HDRI in Unity

Once you have added an HDRI to your Unity scene, you can use it to create more realistic lighting and reflections. Here are a few tips on how to use HDRI in Unity:

• Set the HDRI environment. The HDRI environment is the overall lighting and atmosphere of your scene. To set the HDRI environment, click the HDRI Environment button in the Scene View. This will open the HDRI Environment window. In this window, you can select the HDRI image you want to use, adjust the intensity of the HDRI, and set the rotation of the HDRI.
• Use the HDRI in your scene. You can use the HDRI in your scene to create realistic lighting and reflections. To do this, you can use the HDRI as a skybox, or you can use it to create reflection probes.

Here are some examples of how you can use HDRI in Unity:

• Use an HDRI as a skybox. To use an HDRI as a skybox, simply drag and drop the HDRI image into the Skybox property of the Scene component. This will apply the HDRI to the entire scene.
• Use an HDRI to create reflection probes. Reflection probes are objects that can be used to capture the reflections of your scene. To create a reflection probe, click the Create button in the Assets menu and select Reflection Probe. Then, place the reflection probe in your scene where you want to capture the reflections.

Troubleshooting HDRI issues

There are a few common problems that you may encounter when using HDRI in Unity. Here are some solutions to these problems:
