Match position but not scale
I’m sure this is an easy one for many of you out there
I have a composition that has a map layer (solid with a mask defining landmass) and text layers that indicate the location of cities. I’d like to be able to scale the map layer up or down and have the place names continue to accurately represent the position of the city without changing size.
If there’s a way to parent one layer to another so that the child’s position in relation to the parent remains constant without changing scale that would do it. However, I’m guessing this requires an expression rather than parenting?
Thanks

You should be able to use an expression like this:
l = thisComp.layer("MapLayer");
l.toWorld(value);on the position property of the text layers.

If you parent the text layers to the map, you can add a scale expression like this to the text layers:
parentNormalScale = 100;
value * parentNormalScale/parent.transform.scale[0]You would want to adjust the first parameter to be whatever your map scale starts at.

That works perfectly thanks Dan.

Thanks for this resource. I’ve been working on some HUD elements to composite into sports footage and I was able to work “.toFixed(0)” into different script lines to eliminate these ridiculous decimals.
