Ah, I see!
And there's the Distance Factor as well, that limits the edges of the 'movement box', as it were.
Definitely something to play around with...
With that in mind though, it's still hit-or-miss with knowing where exactly that neutral center point is at, from a pixel-number perspective. Is there some tool you use or can recommend that highlights a certain pixel on a screen so that you know what values to use?
As a second semi-related point, I'm not sure where to find the "Global Tracking" option, as I don't seem to have a Preferences tab, only the layer specific Tracking options:
Do you know where I can find those options?
Also, thank you for the help so far!
