but how would I know which gameObject

[midnight marsh]

My solution would've been to find path named Root and delete it to be empty
Can you use ctrl + F to find something by the name of Root?

[cold knoll]

when I search on notepad, there's "attribute: RootT.y"

nothing else named Root

and all the paths are empty

path:

[midnight marsh]

Then it seems the path is not the issue

I'd try moving the animator controller above the Root just to check if that would fix that clip or not

[cold knoll]

lemme try

now it has another missing error

[midnight marsh]

Maybe the issue is as simple that your Animator has no Avatar specified

Even though it's a humanoid avatar animation

[cold knoll]

also other animations show error too, which werent showing before... Like:

[cold knoll]

yeah no avatar is specified

but for the animations that came with the model didnt need to have that ticked

its only happening for mixamo ones

okay i set the avatar now no missing error

lemme check if animations are working or no

the animation isnt working

although no missin errors

but its just T-posing now

and I checked it on preview as well

See this for reference

[midnight marsh]

Humanoid animations require a humanoid avatar definition

Generic animations override transforms, humanoid animations control "muslces" so they're quite different

[cold knoll]

I have set this to humanoid already

in the Rig window

when I move the animation controller to the parent object then the animation works

[midnight marsh]

I guess maybe Humanoid animations handle paths in a different way

I'm not familiar enough with them

[cold knoll]

oh
