    In URP 11, there is a bug in which the top and bottom of the normal map are flipped when the object is reversed to the x-scale -1 or 180 degrees to the y-axis.

    URP 12 has the same bug.

    I also tested it with a dragon crasher. It shows the same bug.(Attached screenshots)

    Reproducible with: URP 11.0.0 (2021.1.13f1), 12.0.0 (2021.2.0b14)

    Hi, can you report this as a bug so we can track it internally.

    Thank you.

    As a workaround, are you able to use Flip property on the Sprite Renderer to achieve the correct normals?

    This function works correctly.
    However, if you need to move multiple skined sprites (such as a typical character), you need to flip the parent object, so this function is not effective.
