Hi Rick – I appreciate the advice.
To answer your question, I have the latest version of CC, just released a couple of days ago, and I'm running C4D r14.041 (not Lite).
Just to make sure we are on the same page. I don't want to use the AE camera to affect the Cineware layer. I want to extract the camera from the C4d file, so I have a 3D camera in AE, and can then composite other elements over (or "into") my 3D scene so those layers align visually to whatever we are seeing in the C4D scene.
In fact, I didn't even plan to use the Cineware layer once I got the C4D data, rather planning to render out of C4D an image seq and import back into AE.
Basically, I have a 3D scene of a town, some buildings... then I want to composite some explosions, etc... but don't want to do that in C4D on planes, but would rather do that as separate layers in AE, so I can control effects on those individually, and then color-grade everything together (with the rendered scene below).
When you extract the camera you should only have one camera in AE and it should have keyframes. You then use turn on Use Comp Camera in Cineware and everything should match.
I just downloaded a sample project using Docucam and I can't figure out how to bake keyframes from the sample. That's what is needed. If I just extract the Docucam camera I end up with no keyframes. Have not figured out how to bake keyframes from the expressions that Docucam used for motion. If you can get that far then you should be good to go. Just make sure that you set Cineware to use the Comp Camera and things should match up.
Ok, clearly some experimentation was in order...
The "good" news is that using a regular camera and target imports into AE, and the data all lines up (despit the world coordinates being rather wonky... but I digress).
Unfortunately that means I've lost most of the day. My fault for not testing as I went!
I totally can't believe that the baked camera data from my other cam is so completely different upon import. The DocuCam offers some fantastic "hand held" feel, that I'm gonna have to accomplish another way.
Wondering if at this point the camera tracking isn't an awful idea this time around.
That is a free docucam preset for AE. You might have some luck removing docucam from your c4d project and just importing the camera. You might also want to check the c4d forums and see if Nyone knows how to bake the expersso in docucam to keyframes.
Thanks again Rick.
Figured it out. Add a new camera and then tie that camera to the Docucam camera using an expresso, then export to AE and choose the new camera.
Found the idea in this thread:
Works like a charm.
Thanks for going above and beyond Rick...
Was totally thinking about some "parenting trick", but wasn't exactly sure how it would work.
I'll give that a shot, thanks!
