Nuke 5 Essential Training was created and produced by Steve Wright. We are honored to host his material in the lynda.com Online Training Library®.
Nuke 5 Essential Training is designed for digital artists already familiar with compositing visual effects using programs like Adobe After Effects or Shake. This course provides a solid foundation in operating Nuke, using the core functions of keying, motion tracking, and color correcting, as well as Nuke’s key strength, 3D compositing. Tour the Nuke user interface, its unique color management system, and overviews of HDR images, masking, keyframe animation, and 2D and 3D motion blur. Exercise files accompany the course.
In order to finish aligning the tile cards, we need to set their size and position. For that, we need an Axis node, and that's why all of these TransformGeos are hooked to this Axis node here. So, I can do a global Rotate, Scale and Positioning. So, I am going to enable that and I am going to start by setting the Axis to default, so I can show you how we set it up. We'll zoom out. First, we are going to need our cylinder back. There is our cylinder.
Remember, right now our cards are little teeny-tiny thing sitting up here. We want the center of those card's arc to be down here where the center of the cylinder is so that when I scale them up, it'll match the arc of the cylinder. So, we'll go back and turn on our card's Axis. Here is the axis for my cards and here is the center of the cylinder. I want the axis of the cards to be placed exactly on top of the center of the cylinder.
So, I'll do that. We'll even push in a little bit, get a little closer, so we can place it more precisely there. Now my cards are very tiny. Let me turn them on so you can see them and there they are. So, now as I increase the Scale, they are scaling up about the center of the cylinder. We'll make them even larger.
Remember, I need to keep the arc of the cards to be in the same place as the center of the cylinder. In fact, I can also rotate the cards around like this to position them the way I want. So, let's increase the scale of our cards like so. We no longer need the cylinder, so we are going to turn that off and turn on our posts. Oops! I lost my cards.
There. So, now I am going to jockey my arc of cards until they precisely line up on my three posts. So, let's rotate these guys around like this there, and let's change the scale a little bit like so there. There we have it. My five cards 1, 2, 3, 4, 5 with about 3% overlap between each card, see right there, arcing between all three posts and sticking out a little bit on each side.
This is exactly what I wanted. Now let's take a look at it in 2D through the camera to see how it looks. I'll switch the Viewer to 2D, and come down and enable the Viewer. Oops! I need to turn on all these nodes, hang on a second. Everybody is turned on. Here we go. We can now look at the composite. There's the car over the background. The only thing I haven't set yet is the vertical position in Y. Let's go back to 3D, and take a look through our camera.
Here is our camera aperture right here. Here's our lineup posts. We can see how the scene is set up from here. Here we go. So, you can see our cards are lined up with our three posts and we have our camera move. We can confirm the camera stays on the cards and doesn't go off by switching the view through the camera. Again, here's our camera aperture right here.
We scrub through the shot and go, yes! We don't fly off the cards anywhere. We don't need the lineups anymore. So, we'll come up here and simply just disable all of that. So, now we have just our camera with all of our lineup references turned off. We can now check that the camera pans across the cards and then we can look through the camera here. Here's our camera aperture right here and confirm that we are staying on the background.
The only thing left to do is we need to figure out how to position it vertically in Y.
