Wiggle for multiple layers, camera parented to 3 Nulls

[Anmol Mishra]

I have a comp with multiple layers arranged in 3d space. A camera parented to 3x Nulls for x, y z respectively.
Where should I apply the wiggle to get a realistic movement when I use the camera ?
Cheers!

You just need ONE 3D null to parent a camera position to, not three. For ease of control you can use another 3D null to control the point of interest.

Then you can add wiggle to both nulls’ positions.

And there are no issues using slider controls with 3D Nulls ?

No, but if you are using sliders to control the null position, the wiggle expression would have to go to the sliders instead.

You may want to add sliders that control the wiggle amount and speed on a separate control layer (such as a small solid) and link them up to the wiggle expressions with the pickwhip so that you can change the wiggle settings in one place for all sliders.
