3d camera
I am working in a 3d projects. I made a cool bg with a vignette and a suddle gradient and I am very happy with it. I placed a logo in front of the bg and I have animated a camera to sort of doll out revealing the logo. Thatn is all good. But I then want the camera to quickly pivot around its anchor and point at some othe rtext I have created.
The problem is when I pivot the camera around the background goes out of frame. I have tried to make the bg a 2d layer but then I lose the vignette.
Maybe I should make the bg layer 3d then nest it in another comp? I dont know?
Maybe I should parent the bg layes to to the camera?
Is there some setting that will keep the bg layer oriented towards the camera at all times?Another question as if this were not long enough I have been playing around with parenting my camera to a null layer and then animating the null layer, this has been work but I was wondering if anyone has an opinion about this technique as far as if it can get me into trouble in some instatnce or just if it is not a good technique to get in the habit of doing?
Thanks for your awsome advice

You need to change the point of interest of the camera. Switch to top view using the menu in the composition panel to see what I mean.

I THOUGHT THAT THE POIN OF INTEREST CAHNGES WHICH DIRECTION THE CAMERA POINTS?

Well, yes, it does. But it has a Z value which controls how far back in Z space it is.
A simple way to demonstrate this is to place 3 small solids in a new comp. Make them 3d, then position them at various Z distances. Add a camera and make the Z value of its point of interest = the Z value of the middle solid. When you use the rotate camera tool, the camera will rotate around this middle solid.
In your main comp, just reduce the Z value of the POI nearer to you and you should get the effect you want.
