Mirror texture not working on prefab

Hi - I’m trying to attach a mirror texture to the side mirrors of a vehicle but am running into issues.

The vehicle model is a prefab, and I added a child Camera to the center of the side mirror.
I followed a guide to create a mirror texture and applied it both to the side mirror and various objects in the scene. The material populates appropriately forthe plane below, but for some reason the side mirror gameobject only shows a single color for the material. Playing around further by sliding the camera orthogonal to the vehicle, it appears (though I’m not certain), that the color shown is the same that is at the bottom left of the camera ‘image’.
Nothing seems to be functionally different in the inspector between the side mirror and plane shown below.

I’m not sure what to make of this, so any help would be appreciated!

Btw I’m using Unity 2021.3.13f1 on a Windows 10 machine.

There are a few potential reasons why the mirror texture is not working on the prefab in your scene. Some possible causes include:

The camera attached to the side mirror is not positioned correctly. The mirror texture will only be accurate if the camera is positioned at the center of the mirror and is oriented to face the same direction as the mirror.

The camera’s field of view (FOV) is not set correctly. The FOV should match the angle of the mirror to ensure that the texture is displayed accurately.

The mirror texture is not being applied to the prefab correctly. In order for the mirror texture to be displayed on the prefab, the material containing the texture must be applied to the prefab in the correct way.

The prefab is not being rendered correctly. If the prefab is not being rendered correctly, the mirror texture will not be displayed on it. This could be due to a problem with the prefab itself, or with the way it is being rendered in the scene.

To fix this issue, you will need to carefully check each of these potential causes and make any necessary adjustments. For example, you can try adjusting the position and orientation of the camera attached to the side mirror, or adjusting the FOV of the camera. You can also check that the material containing the mirror texture is applied correctly to the prefab, and that the prefab is being rendered properly in the scene.

If you continue to have trouble, you may want to try using a different mirror texture, or using a different approach to creating a mirror effect on the prefab. It is also possible that the issue is being caused by a more serious problem with your scene or with Unity itself, in which case you may want to seek assistance from a qualified technical support specialist.
