The speed of the character changes depending on if it is flying up or down.

We're using this setup on our character:




I've tried a few different combinations with the settings, but i can't seem to get it right. Can you recommend settings for us?

In particular, what do you think we should go with for 'Interpolate Option' and 'Extrapolate Option' ?

The way we're observing the Photon Transform View, is that a good way to do this sort of thing?

As we dial up the character's speed the jumpiness gets worse. I really need some way to configure the settings so its smooth regardless of speed.
