Join Chris Meyer for an in-depth discussion in this video Object mattes, part of Cinema 4D and After Effects: Integration.
Next, we want to create a matte that shows us just where this video wall…face is, just where our video in After Effects is supposed to appear and exclude…everything else, including any objects that pass in front of this video wall's face.…To do that, I did a little bit of work on my model.…I went ahead and selected all of the pieces that are part of the video wall face…and grouped it underneath a null object called box faces.…This is very important because any piece of geometry that I have attached to…this null is going to be factored into the track matte I am about to create.…
So, make sure you set this up properly and think about every element that…should be part of that wall face and exclude any part that should not be part of that wall face.…With that done, I'll select my box faces, not the entire group, but just the…faces and I will add a new tag.…Tags>Cinema 4D and this time, Compositing tag, not External Compositing, that was…for location, but Compositing. That's what creates the matte.…
Chris Meyer—a long-time user of both programs—explains how to move 3D worlds from Maxon's CINEMA 4D into Adobe's After Effects and add additional 3D elements that blend perfectly. Chris shows how to transfer 3D cameras, lights, and position data from CINEMA 4D to After Effects; create track mattes to composite new elements into the middle of a scene; and take advantage of multi-pass rendering to quickly remix and even recolor lights, shadows, reflections, and more. Paced comfortably for beginners, this course also reveals numerous advanced tricks and techniques, such as the use of blending modes and how to cast shadows from new 3D layers in After Effects onto rendered 3D elements from CINEMA 4D. Exercise files accompany this course.
