Creating Light Cycle Effects in 3ds Max - Part 9 - Batch Rendering
In this final tutorial, learn how to set up a batch render process to render the scene from three different camera angles.
- Recorded in: 3ds Max 2012
- This tutorial is intended for use with 3ds Max version 2012 or higher.
00:00:00 --> 00:00:08
In this Part 9 and last movie of this series, you set a batch render process
to render three different camera shots to disk.
00:00:08 --> 00:00:17
If the viewport is maximized, which if you followed along it surely is,
press Alt+W to go back to a 4-viewport configuration.
00:00:17 --> 00:00:23
Also, in the Display panel, bring back the cameras into view in the viewports.
00:00:23 --> 00:00:28
There are three cameras in the scene as stated at the very beginning of this tutorial.
00:00:28 --> 00:00:34
Cameras and their targets have been animated through simple keyframing to move
from one area to another.
00:00:37 --> 00:00:43
Leave the top view as is, and assign a camera view to each of the remaining viewports.
00:00:47 --> 00:00:53
Set all camera views to use Safe Frames and make sure they are shaded (F3).
00:00:56 --> 00:01:03
Scrub the animation to see the effect. The first camera is meant to follow the action early on.
00:01:04 --> 00:01:10
The second camera zooms in to get the action somewhere in the middle,
00:01:12 --> 00:01:20
and the third camera captures the punch line, as the light cycle disintegrates
towards the end of the animation.
00:01:24 --> 00:01:31
To render all three camera shots, you could activate a camera view and set up
a render process in the Render dialog.
00:01:31 --> 00:01:38
You'd need to render that sequence, come back when it's done, enable a new camera view,
and start over again.
00:01:39 --> 00:01:46
Instead of this back and forth approach, it's easier to use the Batch Render tool
in the Rendering menu.
00:01:48 --> 00:01:50
Here you can add a view,
00:01:52 --> 00:01:56
and rename it to make it easier what the view is about.
00:01:56 --> 00:02:02
For example, CAM01 would be an indication you are rendering the Camera001 viewport.
00:02:03 --> 00:02:07
It's important to press Enter when you change a view name to confirm that change.
00:02:08 --> 00:02:12
Next you can override the presets found in the render dialog.
00:02:12 --> 00:02:20
For example, you can set this entry to render frames 0 to 155, as seen from camera001.
00:02:20 --> 00:02:24
This will take us nicely all the way into the second turn.
00:02:28 --> 00:02:32
You can also override the output size but we'll leave this one alone for now.
00:02:33 --> 00:02:39
Ultimately, you want to define an output path, a file name and a file type.
00:02:39 --> 00:02:45
Click the Output Path button; create or choose a folder where you want to store
the output images.
00:02:46 --> 00:02:53
Give your file a name and an extension, for example CAM01-.tga
00:02:53 --> 00:02:59
CAM01 is to reflect the name of the view you have created.
All output images will have that prefix.
00:03:00 --> 00:03:07
The "-" is just a separator between the CAM001 prefix and the sequential numbers
based on the rendered frames.
00:03:08 --> 00:03:16
The .tga extension is the file type used for the render. You can use other file types
such as .jpg, .bmp, .png or others.
00:03:17 --> 00:03:20
You either type them in or select them from a list.
00:03:20 --> 00:03:24
A dialog usually pops up with addition properties for the output file type.
00:03:25 --> 00:03:33
In this case, use a 24BPP, compressed, pre-multiplied Alpha type.
This will work fine for the purposes of this tutorial.
00:03:34 --> 00:03:43
A good practice is to render to individual image files and put them together in post,
rather than directly rendering to a movie file like .avi
00:03:43 --> 00:03:51
Of course it's important to choose the view associated with this batch render entry,
in this case, Camera001.
00:03:51 --> 00:03:56
Using the same technique, add a CAM02 entry.
00:03:57 --> 00:04:05
Set it to render frames between 100 and 210. Notice the overlap between rendered frames.
00:04:05 --> 00:04:10
Normally you don't want an overlap so pronounced but this proves that it can be done if needed.
00:04:10 --> 00:04:18
The fact that the prefix (CAM02) is different prevents any conflicts when rendering
the same frame.
00:04:19 --> 00:04:28
Set an output for the rendering (named CAM02-.tga) and assign Camera002 as a viewport source.
00:04:29 --> 00:04:40
Finally, add a third view named CAM03, and assign it to render frames 195 to 600.
00:04:44 --> 00:04:47
Set the output file accordingly
00:04:49 --> 00:04:53
and Camera003 as a viewport source.
00:04:53 --> 00:04:56
You are now ready to render the scene to disk.
00:04:56 --> 00:05:04
But since this takes some time, a few hours at the very least, depending on your system's speed, you might want to do that after hours.
00:05:04 --> 00:05:13
At any rate, when you are ready to render to disk, simply click the Render button
on the Batch Render window and let it unfold.
00:05:15 --> 00:05:20
Ultimately, you are left with 3 TGA sequences,
00:05:22 --> 00:05:28
that you can view in the RAM player,
00:05:36 --> 00:05:41
or that you can compile together into a movie file using a 3rd-party application.
00:05:41 --> 00:05:48
If you already use an application such as Adobe After Effects,
you can certainly compile your sequences there.
00:05:48 --> 00:05:56
There's also a freeware application called VirtualDub that does a good job
of compiling TGA sequences into AVI files.
00:05:57 --> 00:06:01
Keep in mind that when you compile a TGA sequence into a movie file,
00:06:01 --> 00:06:07
you may lose some quality depending on the compression codec you used for the process.
00:06:07 --> 00:06:15
Some of the better compression codecs on the market include Divx, Xvid and H.264
but there are others.
00:06:16 --> 00:06:23
And so finally we come to the end of this tutorial in which you have learned
many different aspects of 3D making.
00:06:23 --> 00:06:28
You learned to create glow effects based on self-illuminated materials,
00:06:28 --> 00:06:32
you learned to animate light cycles to follow pre-determined paths,
00:06:33 --> 00:06:39
you learned to create and animate light trails, and map them with appropriate materials,
00:06:39 --> 00:06:45
you learned how to use a particle system to blow up a light cycle as it drives
through the light trail of another,
00:06:45 --> 00:06:51
and finally how to set up a batch render process to render the scene
from different camera angles.
00:06:51 --> 00:06:57
As always, we hope you have enjoyed this project and we'll see you next time.
