3D Object placement when zooming with active camera

[Tudor “ted” jelescu]

Do you have 2d layers in between 3d layers? That can give you strange results. Make sure that all 3d layers are grouped together.
Also, turn OpenGl off.
What version of AE and what OS/machine you running this on?

Are they clipping during motion or just zoomed in? If that’s the case, check if one of them has motion blur enabled and the other doesn’t.

By the look of your SS’s I presume that the white building stroke is beginning to show? is that it? If so, the layers don’t seem to be rightly placed in the same position on Z. They should have the same Z position so that what will determine what’s in front is the topmost layer in the timeline.

Follow Ted’s tips, also make sure you don’t have any photoshop styles applied.

Hi Ted,

Thanks for getting back to me. All layers are 3D with no 2D in between.

I was having some scaling issues when I pre-comp(ed) the individual bars. They always end up larger than before, so I moved the z-position back a touch to line it up. Think it may be this coupled with the short focal length of the camera I’m using increasing the space between the layers that’s causing all the trouble.

If I include the building outline in the pre-comp, do you think this will sort it out?

Hi Cassius,

There are no photoshop styles applied, all artwork was created using Illustrator. Will place both layers on the same z-position and place the building outline above as you said. Think that should work.

Forgot to mention above that this is in AE CS5 on Mac OS 10.6

Thanks!
