multi-pass tutorials AEC4D?

Antony: It doesn’t work that way. The different possibilties Cinema 4D has to integrate with AE are amazing, but none will just give you a 3D object in AE. One of the things you can get, though, is information that will allow you to isolate the area ocuppied by a 3D object, whch is no small thing. You could then color correct the object or whatever you need. The Maxon site has some tutorials on Cinema 4D > AE integration.
Basically, you have three ways and some possible combinations between them:
* Cinema 4D can export a native AE comp with C4D lights and cameras converted into AE lights and cameras. New in Cinema 4D, you can have other C4D objects converted into AE null objects. This allows you to add AE 3D layers that match the position/rotation/scale of the original 3D element.

* Also, as part of this AE comp, you can have different render channels exported as separate layers. This doesn’t, again, mean 3D objects. But rather that some visual information (transparency, shadows, illumination, etc) are isolated so you can color correct them and adjust them easily. There are other options, like Z distance (so you can fake depth of field or create depth mattes) and Object ID (so you can isolate the area ocuppied by a specific 3D element to modify it). Of course, to take advantage of Object iDs, you have to previously assign them in Cinema 4D (for instance, this element is ID 1, etc.) You do that through Compositing tags,

* Finally, Cinema 4D, like most other 3D applicatons can export RPF sequences. A still image sequence that has the rendered image plus some 3D metadata (again, Z distance, Object ID, etc.)

Hope this helps
