I’m trying desperately to understand 3d layers in AE but no luck.
Here’s the deal:
1- I’ve created a room in Cinema 4d (‘museum’). Then I animated a camera through it (well, let’s say pivoted it around as if on a tripod). Finally I rendered out 450 frames as an image sequence and saved an AE file from it (not multipass).
2- I’ve rotoscoped videos I shot of people walking and looking (saved with alphas – they work).
The idea is to bring the room and the rotos into AE and composite them together. I can bring them both in ( the Cinema generated AE file pulls in all the images from the sequence as well as the camera and lights ). I can even put one of the rotos on a layer above the ‘room’ layers. This renders out fine but it’s not in 3d space. The room and person move around but not in relation to each other. It’s like the floor is moving faster than the person.
When I make either the picture sequence layer or the roto layer a 3d layer, it disappears! I’m viewing through the ‘Active Camera.’ When I view through the ‘Top’ it comes back but obviously won’t render out that way.
Clearly I’m missing something here.

You say that when you view it from the top it “comes back”… I guess that means that when you are looking at it through the active camera it’s laying flat. So maybe you need to rotate the layer on the x axis 90 degrees… I may be way off (no Cinema 4D experience) but that’s the first thing that comes to mind.

I tried the rotation and still couldn’t see it when viewing through the active camera.
Actually, it was way, way off the screen. Don’t know why but on a whim I thought I’d zoom out as far as possible… and there it was! The cg room is 160′ x 80′ so perhaps that’s why the roto was ‘lost.’

When you turn your layers into 3d layers, by moving the z handles the layers can go
behind other layers and will get lost. The sequence files are basically flat like
any other files you import. You need to keep all your layers 2d and try your composite.
