Animated Rig is not moving vertically

  1. What do you want to achieve?
    So, my rig is currently not moving up and down. A video of this issue will explain a lot better on what my issue is.

  2. What is the issue?


    The lower torso is animated to go up and down, but when testing the game… it doesnt move.

Below is a showcase of how the model is rigged. The HRP is anchored (but this shouldnt affect the lower torso movement when rigged and animated properly)

  1. What solutions have you tried so far?
    I have tried basically everything but a re-rig. I am wondering what the issue is with my rig and why the lower torso stays stationairy

Thank you in advance
