One of the most powerful 3D applications on the market, Maya 2010, now includes three complimentary bundled applications: MatchMover, powerful camera matching software; Toxik, a node-based compositor; and Backburner, a network rendering manager for Maya, 3ds Max, and Toxik. In Maya 2010: Getting Started with MatchMover, Toxik, and Backburner, instructor George Maestri demonstrates how to use these applications with Maya's existing powerful feature set to create engaging 3D animations. Exercise files accompany the course.
Now let's take a look at how to animate parameters in Toxik. This is really important for masking or really, almost anything else. Toxik can animate just about any parameter. So let's go ahead and start with the Garbage Mask and then we'll also animate a few other parameters. So, we are going to highlight this Garbage Mask. What we want to do is animate this wiping on the title. So I want to start this right around, say, about half a second in, say around frame 12 or so. Now we do animation using these keys here.
If you click AutoKey, it will key any change that you make. If we want, we can also explicitly set a keyframe and these two allow us to step between keyframes. When we're scrubbing here, you can see that this is pretty much blank, but as soon as we start adding keyframes, you'll start to see little marks in this timeline, which will show us where the keyframes are. So, I am going to go ahead and highlight my mask and I am just going to go ahead and just select these two points and just stretch this over.
Now once I do that, notice how this is turned green. I have a keyframe, so now my first keyframe is here, but of course, I am not going to get animation until I have a second keyframe. So I am going to move that over, say, to maybe about 72, so that would be about couple of seconds in and I'm just going to go ahead and move that over so it completely reveals my text. Now you can see I have got this basically wiping on. So, it starts here and we do a basic wipe.
So that's the basics of how to set keyframes. Now if I want, I can step through my timeline by going from keyframe-to-keyframe, here and here. If I want to modify a keyframe, all I have to do is just go to the Animation tab and whatever I have selected, it will show me the animation for this and it really is just a curve editor. If I want, I can frame all and you could see I have my curves. I can select a curve. I can change values if I want, just by typing them in or by clicking and dragging.
Now in addition to position, we can also change any other parameters. Once we have wiped this on, we want to actually let it sit for about half a second and then fade it out. So let's scroll out to say about frame 112 or so and then let's start a fade out of this particular title. Now where would we actually do a fade out? Well, we could insert some sort of operator here, but actually, the Blend Comp is a great place to add in a fade. So, I am actually going to go to my Blend Comp node here and I am just going to go ahead and set a keyframe for that.
So just go ahead and hit keyframe and now, I've set a keyframe and I've set it to its initial state. So in order to change the Opacity, first thing I need to do is start at 1. So, the easiest way to do this is just to do a quick jaunt. So I am going to actually lower the opacity and bring it back up and notice how a little bar comes across there and that tells me that that is now animated and I have a little click right here. Now I am just going to move forward a little bit and just dial that down to 0.
So now, I've got it fading out. So, we have done two sets of keyframes. We have actually used a Garbage Mask to wipe on our text and we've used an Opacity to fade it out. Now this works for basically any sort of values, so you can do things like change color, you can add or reduce blurring. Any sort parameter can be animated in this manner.
