Hi, I'm animating text in 3D and trying to do x and y rotation reveals on specific words. When I do a y rotation of +90 degrees, and look at it in front orthographic view, the text disappears, as it should (because it has no extrusion depth). However, when I put a 3D camera in the scene, I can see a great chunk of the text hanging in space, about to be rotated back to 0 degrees. I can manoeuvre the 3D camera so that I don't see the sliver on one word, but it's difficult to do this so that all the slivers for all the rotation words in a chunk of text are hidden. Why is the camera not operating in the same way as the orthographic front view? I guess it has something to do with lens size, but I have tried various lenses and can't seem to get the camera to stop showing the slivers. Is there any way to have a camera instantly behave like the front orthographic view?

From Darby Edelen

You can't render the Front view. You can, however, create a camera with a ridiculously long focal length (zoom) that would almost eliminate perspective. You could link the camera's Z position to its zoom:

x = thisComp.width / 2;

y = thisComp.height / 2;

z = -cameraOption.zoom;


Then keep increasing the zoom value until it looks close enough... or AE crashes (;

Alternatively, you could adjust your rotation values for each letter individually so that it rotates to exactly the point it needs to be to disappear from view, rather than setting it to 90 degrees and then trying to compensate with the camera. If you combine that with trimming the start of the layer to your first rotation keyframe, any slivers that do appear on that first frame won't matter because it will just feel like part of the reveal.
