Harness the power of the CINEMA 4D MoGraph module to create complex animations with only a couple of keyframes. By stacking multiple MoGraph effectors, you can achieve nice-looking animations quickly and easily, saving you time spent keyframing moves manually. Discover how to change your text on the fly or create iterations of it, while keeping the animation intact. Author EJ Hassenfratz introduces a real-world postproduction workflow, by creating a network bumper promo. This project covers creating 3D text in CINEMA 4D, compositing, and adding final polish to the footage inside of Adobe After Effects.
Setting up your object buffers in CINEMA 4D is very important for when you need to isolate certain objects in the scene for any reason. In this movie, I'll show you how you can use the object buffers to isolate the cube text so you can change its color. So in our project window here, if you go look under Special Passes, you can see we have our object buffer 1 that we rendered out of CINEMA 4D. Let's double-click this and see what it looks like. You can see that this is basically just a black-and-white matte that just has our cube text on it.
So we'll be using this as a matte to cut out the text from our main scene and isolate it so we can just change the color. So let's close this window. So the main two passes that we'll have to deal with are Specular and Diffuse, because this contains most of our color information. These other passes are just overlays that just have reflection and shadow. We really don't need to worry about those. Let's unsolo those. What we're going to need to do is just select both of these and make them a Precomp, and I'll do this by holding Shift+Command+C. I'm just going to name this pixel_precomp.
And so you see we have just these two passes as its own comp now. And I am going to duplicate this because I'm going to use one that's going to have a whole cut out so we just have our text. So I'm going to bring in our object buffer 1 pass, bring into our scene, and I'm going to use a track matte on our pixel precomp so it's going to refer to, and use, this object_1 layer as a matte. I'm just going to use a Luma matte.
Now if I solo just this layer then we just have our cube text, and that's exactly what we want. So to change the color, we need to first precomp both the matte here and the comp. We'll just name this text_matte. And if I solo this again, we have our text here. So we're just going to change the color on this, and we're just going to use a Hue and Saturation effect. So we're going to go under Color Correction > Hue/Saturation. Now all I have to do to change the color is since I have the Hue and Saturation on this text_matte, what I'll have to do is scrub this Hue wheel and you see we can easily just change the color on just our text.
So, say the client says that they want a different color, like orange, to use for the text. You can simply and easily just do that all inside of After Effects. You don't need to go back into CINEMA 4D. So you can see how important it is to render out object buffers, just in case you need to make a simple color change like this on a certain object. This saves you from having to change the color in CINEMA 4D and having to re-render the entire project.
