Join Chris Meyer for an in-depth discussion in this video Assigning an object buffer, part of After Effects Apprentice 17: Video Walls in CINEMA 4D Lite.
- Our next task is to create a mat…that cuts out our video in After Effects…to match the bezel of that video wall in CINEMA 4D.…To do that, we need to create…something called an Object Buffer.…I'm going to switch back to CINEMA,…select Cap1 again, which is that surface of the video wall…that's supposed to have the video.…Go up to the Tags menu again…in my Object Manager,…and this time choose CINEMA 4D Tags,…Compositing.…Not External Compositing,…but Compositing.…I know, a little bit confusing,…but they're both very useful.…
When I select Compositing and add that tag,…I get a series of different options for this layer,…including the ability to create an Object Buffer.…That says create a high contrast black and white layer…that only is white where this layer is visible in the scene.…Whenever it's obscured by another layer,…blot it out and make it black.…That makes a perfect track mat…to use back in After Effects.…So I'm going to Enable the Object Buffer for my Cap1.…Next I need to tell CINEMA 4D to actually export this.…
These courses are designed for users who are familiar with 3D space in After Effects, but who have never used CINEMA 4D. This course includes an overview of the C4D Lite user interface, as well as setup information you need to know whenever you use live C4D layers in After Effects. A bonus chapter shows how to set up a C4D Lite and After Effects scene to maximize production efficiency—and minimize render times.
Look for the upcoming courses After Effects Apprentice 18 and 19 for more C4D Lite projects.
