Do you have any lights in your scene or any cameras? I ask because there are two main causes for this type of thing.

Cause 1: Lights in scene not illuminating your layer. Add lights, move lights, or move your layer so that light falls on it.
Or set your layer's properties to not accept lights.

Cause 2: Camera not seeing object. When you turn a layer 3d, it pretty much defaults to AE's world space center. So, if you're looking through a custom camera or an alternate view you may not be looking at the layer.

I don't think it is either of these as the 3D Object is still shown and I am looking through the active camera.
Here's two screen shots, maybe they will help

I see that you have a 3D Camera layer (naturally), and that your background is also a 3D layer... but the two layers in between are still 2D.

When you mix 2D and 3D layers in a comp, you're just asking for trouble, not to mention confusion. If you can't change those 2D layers into 3D layers, it's time for Plan B.

Where is your light source? If it's behind your layer it's gonna be black. Either move your layer forward in 3d space or your light back.

If that doesn't work, do as Dave suggested and turn those other layers 3d and/or get them above or below all the 3d stuff.

I know it's been years since you asked this question, but I'm sure there are others, like me, who got this thread in a search and found no solution. I'm not sure if this is the same thing, but I had 3D text which was animated in a pre-comp. But when I brought it into my main comp, the background went black. And my Y-axis rotations were weird; there was no perspective. After almost punching my screen I realized that my Comp Camera was set to Front. After switching it back to Active Camera, all was well.

Wow. I feel dumb. My camera was set to "front" as well.
