Question

Getting global coordinates from parented local coords.

I have a mocha tracked null. I child another null thats slightly offset in XY. Now the child's coordinates are relative to the parent. But how can I get the child's true position in the comp?

This seems too easy:

thisComp.layer("parentNULL").transform.position + thisComp.layer("childNULL").transform.position

Am I missing something?

That should work if they're both nulls, but this is probably the better way to do it:

thisComp.layer("childNULL").toWorld([0,0,0])

Or maybe this, if it's all 2D stuff:

thisComp.layer("childNULL").toComp([0,0,0])

    Aha! Fantastic! I was getting some minor misalignment errors with my method. Yours is spot on! Thank you!
