Skinned mesh in animation editor keyframes are not visible

Hello! i need help about the skinned mesh keyframes doesnt show on animation editor (it works on other skinned meshes)

can someone help me about this?

That looks as if the PrimaryPart of the rig isn’t the RootPart OR the RootPart itself isn’t anchored.

wdym by that the primary part of the rig is rootpart but the other skinned meshes rootpart is unanchored too so what is the problem the other skinned meshes work without problem

tried the methods u said and still the same

So I assume you anchored the PrimaryPart of the model?

no but i solved the problem with adding motor6 to humanoid root part
