Parasite move in my inplace animation

I have a problem with a basic animation. I want to animate the 2 sides of a window. So I created a basic animation in Unity, with 2 rotation keyframes, at start (closed position) and at the end of the animation (opened position). When I look the preview in the Animation window, the animation works good, but when I click Play mode, the 2 sides of my window have a parasite move during the rotation animation. Has anyone ever had this problem?

Thanks a lot for all the help you can give to me :slight_smile:

Hi, What do you mean by “parasite”?
I made a simple window open clip, is it something like you said?

Yes, it’s an animation looking like that, but with the pivot point of each part, on the extern side of each part of the window… And the parasite move is a translation of the 2 parts, invisible on the Animation editor, but visible on Play mode… But we have an idea: it would be a problem of Game window refreshment… is it possible ? thanks a lot for your answer :slight_smile:
