    Does anyone know if iOS build supports or is suppose to support tessilation in my shaders.
    Currently when I turn tessilation on it renders black for iOS but not macOS, I want to know if I should go ahead and log a bug with unity

    Hi!
    It depends on the amount of bugs submitted.
    It hasn't been processed yet, which means that there were many during the last week(s) :)

    Are you running on device that supports tessellation? For that you need A9 GPU and iOS10+

    Im not even able to build to a iphone as the tessellation is breaking in the editor. It either does not tessellate or it renders black but when I switch to MacOS it works in the editor.

    Sounds like you have graphics emulation turned on.

    Just double checked that, I see " no emulation" and "shader hardware tier 3" checked.

    ok i got ya - the problem is tier3 on ios is not the same as tier3 on macos - you can compare the two in graphics settings. Just to make sure i DID change ios tier3 to be as fancy as macos one and it looks more or less the same as macos

    Hey Alexey, sorry I don’t think I understand, are you saying that tessilation is only supported at tier3 and that iOS defaults to a lower tier? And if I switch to iOS and tier 3 it should all work? Sorry I’m a bit new to unity graphics

    Ok turns out turning off graphics emulator fixes the texture not rendering but I can’t see the tessellated mesh in wireframe. It also appears very jagged. I’m I running into any know issues or is this user error again

    Thanks for everyone’s patience on this
