Hello !! When I scale the shoulder backwards, it also gets resized vertically making it look weird ! Can you tell me how I can fix this ?
Make sure you are scaling in the backwards and forward axis only which is the Y axis. You can do it with the gizmo being the green handle as in the video. If that's not what's happening, maybe you can add some screenshots or better yet a video screengrab so we can see the problem in action.
