How to Implement Sprint / Crouch speed?

[BenNadler]

Hi! I'm struggling to override Sprint and Crouch speed using Enhanced Input Actions, and trying to better understand how those are implemented.

In code I see that MaxWalkSpeed = RunSpeed;

On my Input Action for Sprint, manually overriding MaxWalkSpeed has no effect and seems locked to the RunSpeed value.

I also see that MaxWalkSpeedCrouched = RunSpeed * 0.33333333f; but I see no perceptible change in movement speed when crouched. My camera height is lowered but I'm still moving at the default speed.
