    Hi,

    I'm currently working with Unity 5.3.3f1.

    I'm adding some features using 3D Touch and iPad Pro Pencil.

    When using 3D Touch devices such as iPhone 6S the Touch.pressure value works fine.

    The problem arise when using the Pencil on iPad Pro. The angle data works (Touch.altitudeAngle) but both Touch.pressure and Touch. maximumPossiblePressure return 1.

    I know iPad Pro does not have a 3D Touch screen but the Pencil definitely support pressure and the feature is used often in drawing applications.

    Looking at the Touch API I couldn't see any other property that might hold that information.

    Is this a bug? or maybe a feature that is still a work in progress?

    Thanks for the help

    Hey there,

    Touch pressure was added to Unity for the 3D Touch devices so it only supported those at that point. When the Apple Pencil support was added we have overlooked the fact that our code checked for 3D Touch in order to see if pressure is available. Just late last week we actually noticed this and started working on a fix. So yes, at this point touch pressure for the Pencil is broken and we're working on getting a fix out soon. Thanks for the tip!

    Hi,

    Thanks for the update.
    Make sense, I look forward for the fix on this issue.
    Do you have a rough ETA?

    This has already been fixed, the fix should land in the following two weeks or so.

    Hi @Jaynesh

    Could you make a bug report about that? Otherwise you leave me guessing which Unity version you're using and how you're coming up with the conclusion that it doesn't work. Thanks!

    @inkredibl Different issue but related:
    Please also add support for Wacom pens with pressure and tilt, not only on Mac but also on windows.
    because right now pressure works on the Mac OS because of the touch pressure support but not on windows.
