|
|
This script exports the UV face layout of the selected mesh object to
|
|
a TGA image file. Then you can, for example, paint details in this image using
|
|
an external 2d paint program of your choice and bring it back to be used as a
|
|
texture for the mesh.
|
|
|
|
Usage:
|
|
|
|
Open this script from UV/Image Editor's "UVs" menu, make sure there is a mesh
|
|
selected, define size and wire size parameters and push "Export" button.
|
|
|
|
There are more options to configure, like setting export path, if image should
|
|
use object's name and more.
|
|
|
|
Notes:<br>
|
|
Jean-Michel Soler (jms) wrote TGA functions used by this script.
|
|
Zaz added the default path code and Selected Face option.
