# Screen goes black when camera reaches a point in 3d space.

Hello,

I simplified a more complicated comp to try and figure out what is going on, but i can't for the life of me figure it out. My camera begins zooming toward a 3d layer way in the distance. All is fine until it reaches a certain point, then the screen goes black. The camera hasn't run into the layer, i don't think lights have anything to do with it. It just goes black. Any ideas?

The first image is when the camera begins panning. The second is when the screen goes black. Notice that the camera is still quite a distance from the 3d layer.

Thanks!

It's hard to tell because we can't see the position values for the camera and the layer.

I'd guess that you've experienced a orientation flip because the camera passed 0 in Z and the Point of Interest for the camera is at 0. This can be avoided in a number of ways. Reveal the Rotation, Orientation and position properties of the camera and I'll know for sure.

It would also help you diagnose these problems if you opened up View Options and turned on Camera Wireframes. I have mine set to always.

Hi Rick. I'm guessing that's the problem. The camera has a position of -10.x in the previous frame (image still showing), and the next frame has the value 6.9, and the view goes black. Is there a way to fix this without having to readjust the positions of all the layers?

If you turn on wireframes you'll see that your camera is not pointing at the layers. I don't know why you've animated camera rotation. Do you have the camera oriented to to path, is the point of interest turned on? You could be experiencing gimball lock.

The best way to animate a camera is to make a 3D null the parent. Now you've got a camera on a dolly. Gimbal lock is not a problem, point of interest is not a problem, and everything is easier.

Cool, thanks. I'll try that out.

The rotation is animated because the camera flies through the middle of a logo (the logo layer was turned off), and the rotation added a cool effect

Parenting the camera to a null works like a charm. Many thanks.
