Why did you remove the rigidbody.MovePosition() part? Without it, the model won't move.

I experience the same issue, the player does not move, it just animates on the spot but does turn. What code is missing please?

Same here, no motions are animated. The character will rotate or glide forward. The image of the Blend Tree inputs is to small.
Can't tell what the settings actually are. I do get a warning that two or more of the positions are too close to each other with the
settings I guessed at... Idle: 0,0, 0.1 Left: -1,0,1 Right: 1, 0, 1 and Run: 0, 0, 1 What are the correct Blend Tree settings? Is this
what's keeping the character from animating? Also I put the Base Controller on the character because you didn't exactly mention
where to put it.
