Once you have everything in place it's time to do your final render. Now Maya has several options for rendering multiple frames. We can do what's called a batch render from within a single copy of Maya or if you have multiple machines, you can actually do network rendering. I'm not going to get into that. It's actually covered in the Maya 2010: Getting Started with MatchMover, Toxik, and Backburner title. Now Backburner is actually what you would use to do network rendering. I am just going to show you how to batch render on an individual machine.
Now before we actually render we need to kind of set things up. We need to make sure our project is set, and then we go into our Render Settings window. This is where we actually go to our Render Settings window, and this is where we're going to set up our file name. So let's just call this Dog_Scooter, or we could use the actual file name of our project file. Then in Image format, do we want a JPEG, Targa, Maya, IFF? I am just going to choose JPEG, because it's easy. Then what type of extension? Do we want just the name of it or the name of the extension? These are for single frames.
If I am only rendering one frame, all you need is the name of the file. But if you're rendering multiple frames, you need a number. So typically what I choose is I choose either this one or this one, which is the name, the number, and then extension or the name, underscore, the number and the extension. But I would like some leading zeros here. So I am going to go ahead into Frame padding and go ahead and put in two leading zero. So I have got a total of three digits for this number in the file name. Now I got to tell it what to render.
Well, this is 96 frames long. So I am going to go from 1 to 96. This'll save file name from Dog_Scooter _001 to Dog_Scooter_096. And then which camera am I going to render? Now in this case, I've got two cameras in the scene. I have my perspective camera and my final camera, which is what I'm looking through here. Well, I actually don't want my perspective camera. So I am going to go ahead and turn that off. Also, do we want an alpha channel for this? Then the resolution and additional render options are, do we want to enable the Default Light? This is only if there are no other lights in the scene and any scripts that we want to render.
So once I have all of this set, I want to make sure that my mental ray settings are also set, but I have already gone through that. I have done a couple of test renders. I know everything is set. I've turned on Motion Blur, for example. So I should be all ready to render. So then all I have to do is just start up a batch render. So I can find that under Rendering > Render, and now we have what's called Batch Render. So if I pull up the tool options for this, do you wanted to give me warning messages? How many threads do you want? That depends on how many processors or cores are in your computer.
You can have as many as you want, or you can specify the number of threads. Auto Render Threads basically just takes as many processors as it can. You can also limit the memory. So if you don't want to take more than a certain amount of memory, that's fine. Do you want to render on the local machine or on network machines? I am going to turn off network machines, and then I am just going to do Batch render. Now what this does is it actually starts rendering within Maya. So if you notice down here on the status line, it says Rendering with mental ray, and it will go ahead and start rendering each individual frame.
Now as it renders, you'll go ahead and see the file start to show up. Now remember Maya only renders image file, single image files. It does not render movie files. And this is actually really good, because if it bombs out in the middle of a render, you still have all the single image files that it's created. That's really kind of the technique you need to use for almost any 3D rendering package. So as the file gets done, it will go ahead and tell you here when the images are done and if we want to, we can actually go ahead and view those by going File > View Image, or we can do View Sequence as we get more images going, but if you do View Image, we go into our images directory and you could see already we've got our images are showing up.
So we've got image 001 and image 002. Now this may take a little while to render, but once we are done, we will have this ready to go. So now we've finally got the movie rendered and let's go ahead and take a look at what we have. So we are going to go ahead and do View Sequence and I'm going to go to my Chapter_11 project into my images directory, which is where it put all of that, and then just open the first image file, and that will go ahead and open the whole sequence.
So there you have it. Here you have some batch rendering and some final output for your Maya file.
