# (c) jm soler 07/2004 : 'Procedural Texture Baker'
# Based on a Martin Theeth' Poirier's really
# good idea :
# it makes a rvk mesh with uv coords of the
# original mesh.
# released under Blender Artistic Licence
#
# 0.2.2 : if the uv mesh objet exists it used,
# no creation of a new one. As the lamp and
# the camera
# 0.2.1 : This script automaticaly frame and shoot the
# new uv mesh . The image file is saved ine the
# /render folder.

# On user-friendly side :

#- Tadje Vobovnik adds the Select Image Size Menu

Texture Baker:
This script saves an uv texture layout of the chosen mesh, that can be used as
an uv map for it. It is a way to export procedural textures from Blender as
normal image textures that can be edited with a 2d image manipulation program
or used with the mesh in games and other 3d applications.
Basic instructions:
- Enter face mode and define uv coordinates for your mesh;
- Define its materials and textures and set "Map Input" coordinates to UV;
- Run this script and check the console.
