This script exports meshes (including vertex colors) to VideoScape File Format.
|
|
||||||
|
|
||||||
The VideoScape file format is a simple format that is natively supported
|
|
||||||
in Blender. I wrote this module because Blender's internal exporter
|
|
||||||
doesn't export vertex colors correctly. Check the source for a *fast* algorithm for
|
|
||||||
averaging vertex colors.
|
|
||||||
|
|
||||||
Usage:<br>
|
|
||||||
Select meshes to be exported and run this script from "File->Export" menu.
|
|
||||||
|
|
||||||
Supported:<br>
|
|
||||||
Exports meshes only. Hint: use ALT-C to convert non-mesh objects,
|
|
||||||
and CTRL-ALT-A if you have "dupliverts" objects.
|
|
||||||
|
|
||||||
Notes:<br>
|
|
||||||
Before exporting, the mesh must have vertex colors. Here's how to assign them:
|
|
||||||
|
|
||||||
1. Use radiosity!
|
|
||||||
|
|
||||||
2. Set up lights and materials, select a mesh, switch the drawing mode
|
|
||||||
to "textured," press the VKEY.
|
|
||||||
|
|
||||||
3. Press the VKEY and paint manually.
|
|
||||||
|
|
||||||
4. Use a custom script to calculate and apply simple diffuse shading and
|
|
||||||
specular highlights to the vertex colors.
|
|
||||||
|
|
||||||
5. The Videoscape format also allows vertex colors to be specified.
