Intimidated by 3D modeling packages? Dip a toe in the water with CINEMA 4D (C4D) Lite, a slimmed down version of CINEMA 4D included with After Effects CC. Motion graphics designer Angie Taylor shows you how to build a complete sequence in C4D Lite, progressing from initial object modeling, to animation, lighting, camera rigging, texturing, and final render. Plus, learn to animate text, create random movement with wiggle expressions, track cameras in live-action footage to add new 3D elements, and light your scene. Angie also round-trips the project files to After Effects for visual effects and color correction. With over 100 videos, this course allows you to explore almost every aspect of 3D motion graphics creation, within this accessible introductory tool.
So (UNKNOWN) You can also add passes for object buffers and an object buffer is basically a matte that you can then use in After Effects to isolate objects within your 3D scene. So for example, if I wanted to change the color of one of the robots, in post-production, I could create object buffers for each of them, and isolate them. And that's what we're going to do here. I'm in Chapter12_02.c4d.
And if you want to follow along you can open that. So I'm going to select my main robot, and I'm going to go up to Tags > Cinema 4D Tags > Compositing. So anything to do with compositing is usually applied using a Compositing tag. So if you want to composite elements in After Effects, there are two tags that are important. Compositing tags and external compositing tags. We're going to, first of all, look at compositing tags. These are used to create Object buffers.
Now if I go into my Attributes and we click on the Tag, you'll notice there are several tabs here, one of them being Object buffer. Now we've already had a quick look at the tag section, where we can do things like prevent something being seen by a camera. Adjust the shadow options. Whether something casts shadows or see's shadows for example, but in here we're going to into the object buffer section. And we're basically just going to say Enable a buffer for this element.
And it give it a number, so we're using buffer number 1 for our main robot. Now, when you do that, you also have to go to your Render settings, so we'll go to edit Render settings. And you need to add that object buffer to your multipass. So we need to go into the Multi Pass menu, and go to Object buffer. Select Group id one which matches this one, and you can also rename these object buffers. So I'm going to call this robot 01.
So I've now got a pass for robot 01. Now I can go to the picture viewer And I can see that object buffer and you'll see that both of the robots are now being selected with that. And that's because one of them is an instance, remember, so a little bit tricky with that. But let's add another one to the main robot instance, so I'm going to go to Tags > Cinema 4D tags > Composting. And this time I'm going to enable buffer 2.
So with buffer 2 enabled, I'll go to Render > Edit Render Settings, go to Multipass and another Object Buffer. This time I'll change the number to 2 and I'll call this Robot 02. So what happens now? Well if I go to the picture view again, you'll see now I have object buffer 1, and object buffer 2 doesn't work. So if you're working with instances, you're not going to be able to isolate the individual objects.
So what I would recommend there is actually duplicating this robot instead of creating an instance, so I'm going to duplicate that one. And then if I just drag it onto my main robot instance and then reset its coordinates, Zero zero zero. Then it should be in the correct place. And I can drag it back down here. And then remove that instance. And now I can go into that one. Enable object buffer two.
And go to my Render settings. And make sure robot two is still there. And now if i go to the picture viewer. We should now have an object buffer for robot one and an object buffer for robot two. So just be careful with instances. Apart from that, this should all work quite well. Now I'm going to also add one for the text. I'm going to go to Tags > Cinema 4D tags > Compositing. Let's enable Buffer 3 for this one. Go to my Render settings.
Multipass > Object Buffer, rename it to Text. And very importantly, remember to change the Group ID Number. So, let's go back to our picture over here and check if all's Okay with that. So, we've got robot 1. Robot two and text all isolate so that we can do post production in After Effects.
