C4D and After Effects Unite: The .RPF ID Matte

Cinema4D AfterEffects RPF

In this tutorial I’ll show you how you can better integrate Cinema 4D and After Effects by using a versatile format called a .RPF.

      very cool TIP man thanks

      Great! Looking forward to more on this… Thanks.

      Have you noticed any difference in render times for .RPF compared to rendering out a tiff sequence?

    5. Joren

      I haven’t, they seem to be very similar, which is nice. I haven’t actually tested it on a very intense scene, but I ran a test on a simple scene and they clocked in identical. Another nice perk!

    6. Joren

      Just as a follow up, I just finishing rendering another test scene, and the .RPF took 4 minutes and the .tiff took 3:40. So, I guess there is a slight difference. Not much, but if you’re rendering a huge scene it could add up. Thanks for the question, nice to do some research and learn something new about it!

      Amazing! Thanks for the tips. Can’t wait for the next tutorial on this topic.

      Great – a very COOL tip Joren : )

      One question: does this fix the issue in c4d with the object buffer mattes not lining up correctly (being one or two pixels off from the actual object) in AE? Such a pain not only matting everything in AE but then having to tweak the mattes with matte chokers etc to get everything to line up correctly.

      Thank you so much for finding the time to line this all out for all of us. This particular post was in fact extremely helpful to me.

    11. Joren

      Hey Thomas: Well, I’ve never had any issues with the object buffer mattes lining up with this method, so I don’t think it should be a problem! If you have an issue, let me know though, I would be interested to hear about it. Thanks for checking out the site! Cheers, Joren

    12. Sean

      Awesome tip. When you save in this format, is it just for single images or does it work for animations as well? Would you simply select “all frames” in the render settings? Thanks!

    13. Joren

      Hey Sean, yeah, it works for animation too, just select all frames, or manual and specify which frames you want to render. Should work just as easily as a still frame! Cheers, Joren

      Thanks a heap Joren.

    15. Neekoe

      Hey Joren,

      Thanks for the TIP…

      Just a quick question though. Just tested this workflow and its straight forward and good… BUT I am getting “antialiasing” like artifact on the edge of my object once i apply the ID Matte effect…

      I know you can feather the matte, but would rather prefer a crisp edge like when using the object buffer… Any way you know of getting around that or getting it smooth as eggs…? 😉

      Edit: I exported from C4D with highest antialiasing settings and the raw render looks fine… just as soon as i apply the effect…

      Thanks in advance….

    16. Joren

      Hey Neekoe, it seems like it is a problem some people are finding with the .RPF sequence. Some solutions are to render at a higher resolution and downres in AE or use the choke matte. Nothing really works perfectly though, which is frustrating. I really hope C4D and AE can solve the problem in a future release, because without the aliasing this feature would be perfect!

    17. Neekoe

      Thx for the reply and work around tip,

      Have to agree, if this would work perfectly, this feature would really be one of the best solutions to render/export from C4D for AE…

      Will let you know if I come across anything else i find regarding this…

      Cheers for now, …

    18. Karen

      Hi there, this is a great tip and has worked well for me except for one issue – when I render the .rpf sequence locally on my machine, it works perfectly.

      BUT if I submit the exact same project to a renderfarm, the ID Matte plugin doesn’t work in After Effects??? ie it doesn’t see any Object IDs at all, but it recognises the alpha channel.

      Any clues on why this might be? THanks!

    19. Joren

      That is really strange, Karen. I wish I could help you but I honestly don’t know what the problem is. I haven’t really used render farms too much, so I can’t tell you what’s going wrong. If you figure it out though, please let me know so I can share with everyone. Sorry, and good luck!

    20. Karen

      Hi just found out that this won’t work over NET Renders, Maxon have no plans to fix this apparently!

    21. Joren

      Hmm…very interesting Karen! Thanks for checking into it and for letting us all know! That’s not cool…

    22. Chad

      I’m trying to figure this RPF thing out since it seems like a better way to go, but I keep hitting walls with it. The ID matte system it uses in AE looks extremely aliased compared to rendering out object buffer mattes, and as far as I can tell it doesn’t even support color profiles, so you can’t use Linear Workflow. Those are pretty major deal breakers for me. Is anyone else having these same issues or am I missing something?

    23. Joren

      Hey Chad, I’m afraid the RPF just isn’t perfect, and it works great for some things, but sometimes it just sucks with the antialiasing. I’ve stopped using it for the majority of what I do because it’s just fairly unpredictable…

    24. Chad

      Ok, well now I know I’m not crazy. Thanks!
