Final (?) updates for 2.40 :) : - Bob Holcomb sent a better version of his 3ds importer - Added doc info to bvh2arm: links to doc and mocap tute from author Jean-Baptiste Perin - Alessandro Pirovano improved the Lightwave importer. - Mikael Lagre updated the collada scripts (fixed a bug with camera lens value) - Adam Saltsman improved the wings importer (ongoing work with his pal Toastie). - Anthony D'Agostino GPL'd his scripts (used Blender's BAL license previously) Thanks to all script authors for their work, interest and kindness. Again, Tom (LetterRip) has played an important part in this, thanks and welcome :).

This script exports meshes to TrueSpace file format.
|
|
|
|
TrueSpace is a commercial modeling and rendering application. The .cob
|
|
file format is composed of 'chunks,' is well defined, and easy to read and
|
|
write. It's very similar to LightWave's lwo format.
|
|
|
|
Usage:<br>
|
|
Select meshes to be exported and run this script from "File->Export" menu.
|
|
|
|
Supported:<br>
|
|
Vertex colors will be exported, if they are present.
|
|
|
|
Known issues:<br>
|
|
Before exporting to .cob format, the mesh must have real-time UV
|
|
coordinates. Press the FKEY to assign them.
|
|
|
|
Notes:<br>
|
|
There are a few differences between how Blender & TrueSpace represent
|
|
their objects' transformation matrices. Blender simply uses a 4x4 matrix,
|
|
and trueSpace splits it into the following two fields.
|
|
|
|
For the 'Local Axes' values: The x, y, and z-axis represent a simple
|
|
rotation matrix. This is equivalent to Blender's object matrix before
|
|
it was combined with the object's scaling matrix. Dividing each value by
|
|
the appropriate scaling factor (and transposing at the same time)
|
|
produces the original rotation matrix.
|
|
|
|
For the 'Current Position' values: This is equivalent to Blender's
|
|
object matrix except that the last row is omitted and the xyz location
|
|
is used in the last column. Binary format uses a 4x3 matrix, ascii
|
|
format uses a 4x4 matrix.
|
|
|
|
For Cameras: The matrix here gets a little confusing, and I'm not sure of
|
|
how to handle it.
