    This is NOT FIXED.

    Our work around is to add a duplicate dummy frame either end of an animation. My personal opinion is its a blending issue regarding frames it shouldn't access.

    Animation Frames 1-10
    On the 10th frame it begins to blend between 10 and 11 before eventually snapping back to frame 1. Making frame 11 a duplicate of 10 and not marking it as part of the animation fixes the issue for us.

    This issue is stated as fixed, but it still present in 4.3.2.

    Please fix asap...

    The only workaround at the moment is to re-create the whole Base Layer, on the Second Layer and add the additional clips. This way the masked body parts will work in conjunction with the Base Layer and blend nice to the Overrided animations. The issue, is that we'll have to do the work twice...

    I also experienced this issue when transitioning from 4.2.2 - 4.3, a horrible work around is to fade the layer out at the end of the animation.

    This bug disables a critical feature in Mecanim (though few animations work without this issue arrising).

    This is still present in the release of 4.3.0f.

    Mecanim animation layers are all messed up. Additives don't work, and override animations suffer this glitch described above. The transitions are factoring in the default mecanim muscle pose, causing the "Twitch" at the beginning and end of animations. This absolutely must be fixed. It is a critical issue for those of us who use animation layers for combat and other non-locomotion animations for our characters as opposed to using messy and state machines.

    Note to the original poster, the wave animation uses animation layers. This is a far-reaching generic bug with the entire mecanim animation layering system. It is not as localized and specific as the description would suggest. This bug affects any and all users of animation layers.

    Editorial note: what's the deal with the emphasis on 2D features??? Why does everybody like 2D retro things so much?!!!!! It's time for mobile gaming to go 3D! Enough of these angry-birds clones!
