Tutorial: Using HDRI as a Skybox for Unity
In Unity, Skybox is a component used to create environment backgrounds. Using a High Dynamic Range Image (HDRI) for the Skybox provides a more realistic environment background. Here are the steps to use HDRI as a Unity Skybox:
Step 1: Download the HDRI Image
Download the desired HDRI image from the web. Make sure the image you choose matches the scene you are creating. The image I'm using is a file from the downloads below.

Step 3: Create the Skybox Material
In the Unity editor, click the "Create" button in the "Assets" window and select "Material". Name the material "Skybox".
Step 4: Apply the HDRI image to the Skybox material
In the Unity editor, double-click the "Skybox" material to open the material editor. In the Material Editor, change the "Shader" dropdown to "Skybox/6 Sided". Then, drag the HDRI image into each of the following 6 properties: Front, Back, Left, Right, Up, and Down.
Step 5: Apply the Skybox material to the scene
In the Unity editor, open the Lighting panel. Switch to the Environment tab and change the "Skybox Material" property to the Skybox material you just created.
After completing the steps above, you will see that the background of the scene has changed to the HDRI image of your choice. This will give your project a more realistic environmental context.
