I though so, thanks for your sensible advice.
I guess we’ll just have to do that. It still is going to be hard work as the 3d team only made one revolve and I made it turn 6 times in After Effects so that I would have the time for all the text, that’s why I was trying to work my way around in After Effects.

Again, thanks for your help.

Oh!
Ahaha…
ok, sorry about that! 🙂

Thanks again for your help!

So Dan,
Thanks again for your great help.
The first expression seems to work better than the second one to me.
I’ll still have to make some adjustments when I move the null on the Z axis and if I rotate the objects, but it works great on the X and the Y

The second expression won’t work.
I can’t seem to make the target.sampleimage function to work, it says it’s undefined.
I’m surely not doing something properly.

Dan,
thanks again for your help.
I’ll try that on monday when I’m back at work and I’ll let you know!

Hi Dan,
Thanks for your answer.
This looks almost right, but I’m having a bit of a problem making it work as I want it to so I guess I’ll spare us some time if I describe you exactly how the composition is set up.

Comp is 1550px X 620px
layer 1 is a Null object with it’s position set to the center of the comp at 775, 310

layer 2 is an alpha matte 300×300 px with it’s position set at 211, 85 and is parented with the null object

layer 3 is the magnify composition wich is 3660px x 1440px and has it’s position set at 987,5 , 395 wich corresponds to the center of the matte layer

layer 4 is a solid layer 48×48 pixels with a circle mask the same size and the position set in the middle of the comp at 775, 310 and is parented with the null object

layer 5 is a solid with different mask to connect layer 4 to layer 6 and is parented with layer 4

layer 6 is yet another solid layer 348×348 px, with a circle mask the same size wich is the frame for the magnify composition and it’s position is 251, 16 wich is yet again corresponding to the center of the magnify comp and the alpha matte layer and is parented to layer 4

layer 7 is the composition to be magnifyed, wich is the same as the magnify comp but scaled down at 43% and positioned at 775, 310

as things are now, the center of layer four is roughly the area that you see magnifyed and is the focal point of any movement I need to do.
What I need to obtain is having the magnify comp (aka layer 3) move around when I move the null object and all it’s parented layer.

If I apply your expression to the null object, it works only if I move the magnify comp.
if I try to apply it to any other layer thing don’t work quite the way I need them to.

Now, I understand I’m basically asking you to do the work for me, but please, help! 🙂

I’ll try and bring “the issue” to the expressions discussion group then, hopefully this could come in handy for other people too!

Thanks again for your answers and patience! 🙂

Thanks for the advice Steve, I guess I’ll end up doing that, but what I hope to do is to avoid moving the composition manually as I’ll have lots of movement and the magnifying lens will move in and out a lot.

BTW my final comp will be 720×576 as I’m in the Pal area of the world! 😀

Thanks again
