LightWave 3D export
 
 
 

The LightWave 3D® scene exported by MatchMover can be imported as is in LightWave 3D.

MatchMover produces a LightWave 3D scene file, a LightWave object for each 3D object in the project and a LightWave object used to create an image plane for each exported camera.

Select File > Load Scene. The scene contains the tracked camera, the 3D points as “null object” and information about the pixel aspect ratio. The output size is also automatically set.

The scene contains:

Synchronized cameras with their respective image planes in case of a MOCAP project.

Compositing in LightWave 3D

If you wish, you can delete the image plane and use the sequence in LightWave 3D as a background image.

Refer to “LightWave 3D User Guide” for more information.

To use the sequence as a background image:

  1. In the Images Panel choose Load Sequence, and choose an image in your sequence.

    NoteCorrectly set the frame offset. If your sequence numbering does not begin at 0 and you enter 1, this would mean that “foo0001.tga” corresponds to frame 0 in your animation.
  2. In the Options Panel choose OpenGL as Layout View Graphics and BG Image as Layout Background.

  3. In the Effects Panel, click the Compositing tab and select your sequence from the Background Image combo.

Now you can start animation on top on the tracked sequence.

Working with interlaced sequences

If your background sequence is interlaced, you should check the Interlaced box in the Images Panel.

  1. In the Camera Panel, check the Field Rendering box.

  2. If you chose Lower field first as the interlace type in MatchMover, check the Reverse Fields box.

Now you can render your interlaced sequence.

TipIf there is a slight apparent motion of the virtual objects with respect to the background image, make sure that you have chosen the right field rendering type and the right frame offset for your sequence.
