Hi there,

I have a question for Unity Play mode on HL2. As you can see on the picture, how can I disabled sky blue background colour?

Hello, welcome to Microsoft Q&A,

Sky background is determined by the Main Camera of your Unity Project. According to Camera setup in Unity, please follow the steps below.

1. Select the Main Camera in the Hierarchy panel
2. In the Inspector panel, find the Camera component and change the Clear Flags dropdown from Skybox to Solid Color
3. Select the Background color picker and change the RGBA values to (0, 0, 0, 0)
4. If setting this from code, you can use Unity's Color.clear

I also noticed your Unity version is 2018.4. According to Choosing a Unity version and XR plugin --

Unity 2018.4 LTS has reached the end of Unity's two-year Long-Term Support window and is no longer receiving updates from Unity, although your projects will continue to run.
If you have a Unity 2018 project, you should consider planning for a migration forward to Unity 2020.3 LTS and the Mixed Reality OpenXR plugin.
