Hey Guys.

found this post, while searching a solution for this nasty little bug, once again.
since I am still working with C4D and AE from time to time i´m running in this issue, while working in linear workspace and multipass renderings.

i guess it depends on the antialiasing, and the gamma/grey interpretations…

these little white matte lines drive me creazy sometimes. especially, because its a c4d/AE problem and there is no nice fix for this, beside switching to Fusion or Nuke 😉

well, here is my workarround:
like the guy from helloluxx in the videotutorial here:

Steps:
-setup the AE projekt in LinearWorkspace and colorspace whatever.
-interprete the mattechannels/Objectbuffers/Depthchannel with “preserve RGB” (so no changes happen to them)
-start comping. Setup the color/beautypass and place the Objectbuffer ontop. (oldschool)
-now: drop effect “set matt” to the Object buffer->create a alpha channel for the mattelayer from his own lumachannel.
-now you created a “real” alpha channel.
-you can enhance this alpha with curves and matt-choke.
In my opinion, the curves effect is more subtle and better for choking the alpha.

well.. its really a workarround and i would like to find a better soultion.. but for today it works.

cheers.
