Inheriting properties, and holding them using an expression.
Hi,
I’m familiar with using the pick-whip to get a layer to inherit properties from another layer, okay, no big deal there.
Does anyone have an expression that will inherit a property (ie. position/scale/rotation) of a null object but then HOLDS the values at the point at which it inherits them?
Would be very useful to me. TIA for any help.

are you looking for valueAtTime?
something like
thisComp.layer(“Null 1”).transform.position.valueAtTime(1)
would give you the position value of null 1 at 1 second. combine this with an if else statement and you could make things happen.

Yeah that would do it, but is it possible to make it even more ‘automatic’. let’s say that the layer that’s inheriting the null’s position has an in point of 2 seconds, rather than type that time value in manually, is there a way that the expression can say “okay, this layers in point is at 2 seconds, what’s the nulls position at 2 seconds? i’m going to take that value and hold it…”
the reason i need the automation is that the comp will be holding a whole heap of layers and in the variations i’m going to be making i’ll be using the ‘sequence layers’ command a fair bit hence the values are going to be changing quite a bit – if they can be calculated automatically then that’ll save me a heap of time for sure.
thanks for your help man.

Like this:
thisComp.layer(“Null 1”).position.valueAtTime(inPoint)
