I need to mirror a mesh (square building window) to fit the right side of the building face.

When I mirror it using Ctrl+M it changes the normal and it looks weird on texturing.

Is there any way to change the normal individually for each mesh? It's a 4 side building hence 4 normals for each side of the building and while doing this.

While writing it I figured out that the color space in the Image Texture (of normal) node is set to sRGB instead of Linear.
