I've got a scene from C4D R15.008 that I'm trying to extract some 3D data in After Effects CC

I've rendered out my passes as image sequences for compositing, but I'm trying to get a few lights and a 3D plane for some additional composite elements of smoke and whatnot in 3D space.

When I bring my C4D scene into After Effects, everything lines up. I've brought in my rendered passes to double check the alignment over the draft 3D Cineware preview.

The problem is, when I try to extract the 3D data, the camera changes slightly. I can't quite tell if it's changing position, or changing field of view or something, but my lights and other 3D elements are slightly off when viewed through my proper camera. When I enable the Extracted camera that I'm trying to use, and then select 'Comp Camera' in the Cineware settings, everything changes position slightly. My 3D objects line up properly with the underlying draft geometry, but now everything is slightly off from my rendered image sequences.

I've double checked that the focal length, angle of view, etc.... is all the same as in C4D and it is. My keyframes from the camera animation are all baked, so that should be a problem. My scene units are in cm.

I can't figure out what is causing the shift, because it's pretty subtle, but it's significant enough to make it unusable.

Is there some gotcha with Cineware that someone out there knows about? Or any particular things to double check in my scene to make sure they aren't translating funny?

Any help is appreciated. Thanks!

Hi Dustin

I have the same issue. Did you find a solution for that?

I've got exactly the same problem

To check it I've exported the cam to afx, brought it back into C4D and compared it to the original - seems to be the rotation is ever so slightly different which puts things ever so slightly out of sync

No solution as yet - let me know if you find anything, it's rather important these line up!

This could be a frame rate mismatch. Check your project settings and render settings in C4D match you frame rate in AFX.
