    Hello,

    I'm learning the Project Survival Shooter on Unity Page. Everything works fine on PC/MAC. However, there are some problem with Bumped / Specular Shader on iPhone. Please take a look to the below picture on my iPhone 6:

    There are some glow on the floor. I've already tried many shader such as Bumped/Specular, Mobile Bumped/Specular, Mobile Bumped Specular (1 Directional Light) and even adjust the shine value but no hope.

    Best Regards,
    An Truong.

    that looks strange. Please create small repro project that shows the issue and bug report it (and drop case number here)

    No. In Unity, go Help -> Report a Bug.

    I have the same issue. It seems that it happens on latest iOS devices (as iPhone 6 and iPad 3 Retina) but only occurs when you have more than 1 directional light in the scene. It seems like on mobiles the calculation of light for the second light saturate the value and gives the white spots.
    The same issue doesn't appear on olders iPads. All my devices are running the latest version of iOS 8.0.
    So I think it's an hardware implementation related to OpenGL ES that differs in the newest devices and cause this kind of error

    I am facing the same issue with the survival shooter demo on iPhone 6. After various experiments, I am certain that it is only the floor texture/shader that is buggy. All the other materials seem to work fine. Glad that someone else found it too. Is the issue fixed or does it have a workaround (I tried different texture quality settings but the problem persisted)?

    Thanks An and Alexey,
