I've just started using after effects and one question pops up immediately:
If I have a text layer in composition and on top of that text layer I have camera layer parented to null object layer, this works just fine. I can change position of that text layer by manipulating that null object layer which is a parent to camera layer.
But what if I add another text layer and I do not want this text layer to be affected by aforementioned camera layer? How to do it?
a) Leave it as a 2D layer
b) put it in a separate comp and combine the two comps in a third parent comp
I strongly suggest you read the help and watch some tutorials. This is basic stuff.
