How to handle side mirror reflections for a car?

Hello - I’m trying to create a side mirror reflection for a car. I’ve tried using the shader and C# script found here:

In the article however, it says that the reflection happens in the “up” or “y” axis of the object - I want to modify the script so that it is reflecting in the “x” axis, e.g. behind vs. from the top. Is there anyway to do this? I’m unable to rotate the side mirror, since it belongs to the “body” of my car.

I apologize if I’m missing something, I’m relatively new to game development.

i suggest using RenderTextures instead of creating reflective mirror shaders.

you can use Reflection probe in your Mirror game object.
