    I created an Ibeam that I wanted to use as a modular piece. I was going to breakup the repetition by scaling the object -1 on the Z as well as the Y, but when doing so I am getting messed up normals? Is there something that I am not doing correct or is there a way to fix this. See Attached.

    Yes I think so, When scaling z -1 you basically reverse the model and the textures on it including the no longer correctly displayed normal map.

    Is the material you're using assigned the standard shader? If so it should be handling this case for you. If you're using a custom shader it's possible it's not handling this properly.

    It's also possible your normal maps aren't quite correct, can post them here?
