Join Chris Meyer for an in-depth discussion in this video Converting a parametric object to polygons, part of After Effects Apprentice 17: Video Walls in CINEMA 4D Lite.
- To composite our video onto the screen…back in After Effects instead of using it…as a texture here in Cinema 4d,…we need to figure out…where exactly is the face of that video wall,…and what it's dimensions are,…as we want to map a video in after effects…to exactly the same location and size.…We also need to create a mat…that takes this frame of the video wall,…and whenever obscures the video…it cuts out part of the video.…So we don't have things playing on top of each other.…Unfortunately, the way that we built the video wall…using an extrude object and rectangular spline…does not give us individual access to that surface.…
We could do some tricks with texturing…to put a texture on just that front cap,…but there's no direct way to figure out…its position, its dimensions,…or when it's obscured by another layer.…No problem.…Whenever you've created a model…inside Cinema 4d using these wonderful tools,…such as lathing, sweeping, lofting, extruding, et cetera,…there is another tool off to the left…called Make Editable.…
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.
