Hi, I have a bunch of animations that I used for one character. Now, whenever each animation plays, the character controller doesn't move with the animation. Is there anyway I could fix this in Unity or do I have to use blender to fix the centering of the animation?
I suggest you change it in Blender. It's generally recommended that Animations such as Walk, stay in one place. To quote from a forum post, Animation resets Character Controller:
"You don't want to animate things moving. You want to animate what they look like while they move. For example, a character walking is animated walking in place, not forward. To have a character walk, you play the 'walking in place' animation while the character controller moves forward, that's how a character walks forward."
And you move the Character Controller by an attached FPSWalker script.
