Bulge adjustment layer doesn't work with position changes

[JonathanBegbie]

I'm working on a simple 'fake' globe effect using a bulge adjustment layer with the center parented to a globe composition layer's position. However, when I try to move the globe's position, the bulge does some weird warping and then settles back into place once the globe is done moving.

I have gone through and adjusted the bulge's radius animation path so that it stays within the globe layer throughout the animation. There doesn't seem to be a clear reason for why it's doing this.

I don't think the radius is the cause, as the weird warping occurs when I move the globe in position only. Please help! Thank you!

It might be a problem with the horizontal and vertical radius of the bulge effect.

You should use an expression to calculate it dynamically based on the scale of the Globe layer.

Try this expression on the horizontal and vertical radius properties of the bulge effect:

scaleFactor = thisComp.layer("Globe").transform.scale[0] / 100;
value * scaleFactor

Thank you for your response. I tried the expression and that didn't change the result at all, sadly.
I think it's something with the position that's being weird, rather than the radius. If I animate the globe size without any change to the position, it looks fine. It's only when I animate the position that things look wonky.

Edit: Did some tests and I think it has something to do with how the bulge works when out-of-frame. Editing the position or scale of the globe when it's in-frame looks perfect. Exactly how I want it to look. It's only when I animate the globe going out-of-frame or into-frame that it has that weird effect. I don't even know if this is fixable now.

Try to turn off Pinning.

Yup! That did it! Of course that caused some of the bottom edge to come up from the bulge heigh, so I made the buldge height increase from 0 to .5 as the globe shrinks, which is a semi-fix and works like I need it to. Thanks!
