    I am on Unity 5.6.0f3 and Mac OSX
    Project is set to iOS (iPhone, iPod, iPad)

    There are no detail normal maps.
    detail Albedo works.

    Anybody else noticed this?
    Thank you

    Can you post a few more details about your project?
    • set up of the material and shader being used.
    • I assume this in editor or are you seeing it in both the player and editor?
    • whether you're forcing any particular graphics API
    • Did you also move editor version or come from a PC to MAC?

    Hey Pete,
    We are using Standard shader:

    Behaviour is similar on both Editor (iPhone, iPod Touch and iPad <OpenGL 4.1>) and Device (iOS, Android)
    Detail normal maps are not visible

    On my another Mac which is set up to PC, Mac & Linux Standalone <OpenGL 4.1> I can see normal detail map in the editor. so it's working there (same repository)

    I do not think we are forcing any graphics API. Just native Unity editor.
    I've tried different emulation settings (and Shader Hardware Tiers):

    but none of them showed detail normal maps

    your last question is a bit unclear to me...I believe detail normal maps disappeared when we upgraded Unity from 5.5 to 5.6
    both my Macs are running Mac OSX.

    Thank you

    Hi Almakos, I've seen this issue occurring with the project going within 5.6, from PC to Mac and also 5.5 Mac to 5.6 Mac where Unity won't default to Metal like it should and the shader doesn't compile correctly. I'm looking into narrowing down the cause of this.

    To get around this for the moment. I've been changing the default values set in the PlayerSettings, for the Auto Graphics API for Mac.

    After forcing metal to be used, you can switch the Auto Graphics API for Mac back to auto. You should see whether it has switched across the top of the editor.

    After doing this, you should see the detail normals working correctly again.

    I just noticed that I experienced a similar issue, also while updating from 5.5 to 5.6 on Mac.

    I fixed it by going into 'Edit > Project Settings > Graphics' and ticking the 'Detail Normal Map' tick-box under one of the tiers in the 'Tier settings' section. All of the tiers had it disabled after upgrading for some reason.

    The editor has been complaining about the Metal API ("Metal: Editor support disabled, skipping device initialization"), so I'm currently using OpenGL.

    I can confirm Almakos' issue. It also is broken on the Windows Version of Unity! The Secondary Normal Map does not seem to work at all using Unity 5.6.0p1! Project built for Windows as well. Everything else pretty much set to default settings. It worked fine before the 5.6 update but after the update suddenly stopped showing on the material.

    EDIT: Ticking the new checkbox, which Evil_Moo mentioned, fixes the issue.

    Also if you experience degraded graphics in the viewport (missing normal maps, missing reflection, etc.) try setting Shader Hardware Tier to 1
