Problem with mixing 2d and 3d in AE7

Hi all,

I'm having a small problem with after effects 7.0, basically what I'm trying to do is to slide pictures over each other. Only, on one point of time picture A should be over picture B, and on the next point picture B should be over picture A (but then with about 20 pictures). Since layer order is not keyframeable, I tried to do it with 3d-layers. So I created a camera with almost infinite focal length, so that when I change the Z-position of layers they don't shift optically in the x and y direction. The problem I'm having now, is that when I use this '3d'-composition in another (2d)-comp, all the seperate layers in the 3d-comp shift, so I am assuming that it uses another camera to render the 3d-comp within the 2d comp than I am using within the 3d-comp, if that makes sense. Anyone an idea how to solve this? Also, if anyone knows another solution to changing layer order over time, that would also be great...

Thanks!

Steven

Try pressing the little asterisk toggle by the precomped layer, if no improvement, post again and we'll see what can be done.

Unfortunately, layer order can't be keyframed, and the second comp doesn't use another camera to view what you have done.

Thanks Conor!

That solved the problem! I almost reached the stage where I wanted to copy every layer ten times to have an instance of every picture over all the others, and then keyframing opacity to make them appear and disappear (nice, 200 layers in a comp). Thank you for saving me that work...
