    Hi guys,
    i have a very odd problem here :/
    I'm using mecanim for my humanoid character and I guess the bones are set up properly in the configuration tab. Also the character is standing in t-pose.
    When the character plays a animation the whole character moves a little bit up and downwards. it doesn't seem to matter which part of the body is moving, the entire character floats a little bit up and down.
    I tried everything, including check the "Bake Into Pose" fields on the animations tab and deactivating "Apply Root Motion". Deactivating "Apply Root Motion" worked well for a similar strange moving problem in my last character setup.

    The Animation plays fine in maya (no unwanted movings of the body) and also with a legacy setup

    Any help will be appreciated.
    I can also upload a video or some pics

    I'm am having issues with MecAnim well (still working on figuring out best animation practices for Mecanim). However, I started having some success when I gave my characters and all the animation files the same Avatar Definition (rather than allowing them to keep the one that was auto generated on FBX import). I have no idea what this did for my particular case, but it help fix knee and ankle issues I was having.

    Hope this helps.

    Hi Holz,

    Yes please upload a video, this will help us to help you.

    Normally such case happen because the T-Stance is not good. If your character float it may be because the character foot are not touching the ground in T-stance.

    Take a look at this thread to help you to setup your T-stance

    Thanks guys for your help :)

    i've done a video to show my problems.
    First you see the animations in maya, they work all fine. Take a look at the foot which is not moving, it stays in the zero position. In Unity, after applying mecanim, adding a avatar, a character controller and so on my character starts to wiggle, if, for example, the wrists are moving around.



    ps. I have read the mecanim setup article, i guess i did it the right way

    Your setup seem to be fine.

    Can you send us your file so we can take a look why it doesn't work in your case?

    Create a small project in Unity and import only this character file, log a bug and attach your project and then send me your bug case number here.

    I'm currently have the same issue as well.

    I've created 2 animations through uMotion and i've tried using both a self-made model and the mixamo robot model.

    While blending between the 2 animations the model's root bone moves, despite none of the animations ever changing its position or rotation (which is exactly what happens in the video).
