I have a bit of an issue trying to get a hitbox to work with my animation. Here's my setup: I have an imported root motion animation I duplicated the animation so that I could edit it in the animation tool in unity I added a child game object to the character with a 2d collider on it (this is my hitbox) I animated the collider to coincide with the punch animation Because the animation for the collider is in the same clip as the mesh animation, it's on the same animation controller (in case that's not obvious). This looks fine in the preview when I scrub the animation or play it in the animation window, but there's an offset when I test in playmode. This is the animation when I set it up in the animation window. Looks fine. Same animation when I test it in play mode: I chose this workflow because it allows the designer to easily tweak hit frames, etc, and you can preview it easily. Having to animate the hitbox on a separate clip/controller would be a nightmare to line up. So, is there a way to fix this, and/or a better workflow to animate the collider? EDIT: This behaviour was observed in 5.6.0, 5.6.1 and 2017.1 Thanks!
