Rung Offset and Rung Separation seem to do nothing

[FadelMS]

Hi,
It's not clear to me what Rung Offset and Rung Separation exactly do. It seems no matter what values you use, nothing changes and the demo works just fine. I even tried to set them both to zero as shown in the snapshot, still the demo works normally.
My understanding is that Rung Separation sets the pace between ladder steps. Am I right?
After all, what do they do?
Thanks

The run offset and separation are used for placement when mounting and dismounting. The actual animation is not IK based so it will play the same no matter what the values are.
