Isolating a Selection for compositing in After Effects
I am trying to isolate a “Selection” with material using a conpositing tag, which is basically the polygon selection of the “screen” in a plasma screen model.
I am saving the resulting file as an RPF so that I can later change the footages displayed on that screen in After Effects.
As someone ever done that over here ?
Thanks,
Vince

Yes, do just assign it an object ID, enable Object and Object buffer (and possibly Coverage) in RPF options and then render to RPF. In AE, you apply the ID Matte effect and that’s it. Two things, though: aliasing for the selection/matte usually is pretty bad. And also I believe you have to use a square pixel ratio when going from C4D to AE.
IMHO, Cinema 4D’s own exchange worflow with AE (its’ ability to export a native AE comp) is better than RPF. Among the multi-pass channels you can use this kind of matte too.Adolfo Rozenfeld

Perfect, thanks for the native export tip as well. I was just used to exporting as RPF using my previous 3D Software and never looked further.
Thanks, again,
Vince
