However, in the following image, I am idle, and the legs move with the torso in the animation. I want the legs to stay still, as if they continued with the idle animation.
If you tilt the HumanoidRootPart in your animation I think the hip, neck and shoulder joints tilt along with it.
If the torso is tilting back 5 degrees then tilt the legs back 5 degrees as well so they appear straight up and down.
The problem with that is that by moving the legs, they are added as a keyframe
This means that that is part of the animation and will play regardless, meaning if I’m walking it will look as though I’m standing still
