Animating Text in 3ds Max - Part 5 - Using Audio Files

In this tutorial, learn how to use the Motion Capture Controller to control the animation of an object in real-time with either a mouse or keyboard. Here, you use the mouse to control and record the rotation of the trumpet as the music plays.

Transcript

1
00:00:00,436 --> 00:00:07,755
In this final movie, you'll use your computer mouse to control the rotation of the trumpet in real-time, as the music plays.

2
00:00:08,251 --> 00:00:13,746
Select the Trumpet and freeze its rotation using Alt+Right-click.

3
00:00:16,863 --> 00:00:18,531
Go to the Motion Panel.

4
00:00:18,930 --> 00:00:25,650
Expand the Assign Controller rollout and select the second rotation track in the list, Keyframe XYZ.

5
00:00:26,383 --> 00:00:29,528
This will allow you to work on the object's local axes.

6
00:00:29,966 --> 00:00:35,431
In this case, you want to control the horizontal rotation around the local Z-axis,

7
00:00:35,800 --> 00:00:40,850
and the vertical rotation around the local Y-axis.

8
00:00:44,508 --> 00:00:52,413
With the track selected, choose Assign Controller and choose Rotation Motion Capture. A dialog appears.

9
00:00:53,179 --> 00:00:59,564
Click the Z-Rotation button and assign it to a Mouse Input Device, in Horizontal mode.

10
00:01:00,387 --> 00:01:05,659
Reduce the scale to 0.1 as the default value of 1 is usually too sensitive.

11
00:01:06,564 --> 00:01:13,084
Set the Y-Rotation to a vertical mouse motion and again, decrease the sensitivity.

12
00:01:13,801 --> 00:01:17,234
Keep the dialog in check and go to the Utility panel.

13
00:01:18,050 --> 00:01:25,390
Click on Motion Capture. You may get a MIDI device error. Don't worry about it, we are not using a MIDI device for this scene.

14
00:01:25,987 --> 00:01:30,947
Highlight the trumpet rotation track and then click the test button.

15
00:01:31,882 --> 00:01:35,802
Move your mouse around and see if there are any problems with the behavior.

16
00:01:36,280 --> 00:01:38,900
The vertical motion seems inverted.

17
00:01:39,540 --> 00:01:41,350
Right-click to cancel Test mode.

18
00:01:41,723 --> 00:01:47,116
To correct the problem, simply enable the Flip option on the vertical mouse motion.

19
00:01:47,848 --> 00:01:53,453
Try it again. This seems better. Remember to right-click to end testing.

20
00:01:53,948 --> 00:01:58,335
If you wish, you can playback the animation during testing.

21
00:02:08,635 --> 00:02:18,456
When you're ready to record the animation, make sure the Record Range Out value matches the length of your animation, in this case 1000.

22
00:02:19,410 --> 00:02:22,070
Click Start to start recording.

23
00:02:54,776 --> 00:02:58,314
At the end of the animation, rotation keys are generated.

24
00:02:58,921 --> 00:03:05,319
By default, there is a rotation key for every frame but you can reduce these to a more manageable number.

25
00:03:05,640 --> 00:03:09,660
In the Curve Editor, select all rotation keys,

26
00:03:11,453 --> 00:03:14,743
and choose Keys > Reduce Keys.

27
00:03:15,200 --> 00:03:21,660
Set the Threshold to about 2 and click OK. The higher the value, the more keyframes are removed.

28
00:03:22,450 --> 00:03:27,833
Be aware that if you set a value too high, you might lose some animation detail.

29
00:03:28,553 --> 00:03:33,621
Playback the animation when done or view the final animation .mp4 file.

30
00:03:37,020 --> 00:03:42,253
In this tutorial, you learned how to control animation behaviors using audio files.

31
00:03:43,011 --> 00:03:47,913
You also learned how to use the Motion Capture controller to control animation in real-time,

32
00:03:48,269 --> 00:03:52,468
using devices as simple as a mouse, keyboard or joystick.

33
00:03:53,011 --> 00:03:55,731
We hope you enjoyed these techniques and found them useful
