    Anybody know why viewing a mesh from a slightly different camera angle would make a material flicker on or off?

    Example:

    upload_2017-8-5_1-6-31.png

    upload_2017-8-5_1-5-47.png

    (yes, this is Scene view in editor, but the same thing happens in the game at runtime)

    Another example (same room) it will flicker between lighting effects (shadows/highlights) and no highlighting effects (flat/albedo only):

    Another example (same room... flickers/wavers between highlight/shadow effects, vs. flat albedo-only style):
    upload_2017-8-5_1-18-8.png

    upload_2017-8-5_1-18-31.png
    (notice shadow on floor and, especially, the light highlighting the wall ... very jarring when these things are suddenly turning on and off in rapid succession)


    PS. This is currently all real-time (not baked) lighting

    Hey @guru20

    Are you using forward rendering path? If so, then you may need to increase pixel light count in Edit > Project Settings > Quality tab
