Character controller applying velocity on it's own

Hi there,

Trying to make my guy climb a ladder. When he's idle on it he slowly drifts down on his own even though I'm applying no velocity at all to him. When I output the controller's velocity it's moving about -0.3 every update.

Not sure what is causing this. I only have one move call for the controller per update and I've confirmed it is 0,0,0 when in this state so something else is moving the controller and I can't figure out what or why. Gravity settings don't effect controllers. The scripted gravity is clearly not being applied. Any guesses? Could slope or step be doing anything? I can't see how.

 

Bump. Basically, just asking for what things could make a character controller move outside of scripting. It is only moving on the y axis. It's like it's applying a small amount of gravity even though it can't possibly be the gravity.

 

Discovered the idle animation was moving the controller.
