This script "bakes" Blender procedural materials (including textures): it saves
them as 2d uv-mapped images.
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 procedurals 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.
Usage:
a) Enter face mode and define uv coordinates for your mesh;<br>
b) Define its materials and textures ;
c) Run this script and check the console.
Global variables
a) FRAME integer, the last frame of the animation, autodocumented .
b) LIMIT integer, 0 or 1, uvcoords may exceed limits 0.0 to 1.0 , this variable
obliges the script to do a complete framing of the uvcoord .
Notes:<br>
This script was based on a suggestion by Martin (Theeth) Poirier;<br>

# (c) jm soler 07/2004 : 'Procedural Texture Baker'
# Based on a Martin 'Theeth' Poirier's really
# good idea : makes a rvk mesh with uv coords
# of the original mesh.
#
# Released under Blender Artistic Licence
#
# 0.3.1
# stupid bug correction
#
# 0.3.0
# TAILLEIMAGE variable
#
# 0.2.9
# -- little probleme with the KEEPRENDERWINDOW variable .
# removed . script seems to works correctly now .
#
# 0.2.8
# -- added the forgotten image property in face
# data. a little longer but better.
# ( a remove double in the resulting mesh may be
# useful .)
# -- the data.update() function problem is
# corrected too
# -- no more layers problem . CAM and MESH are
# localised in layer 20 . This layer is
# the active one for the image rendering .
# -- mesh creation is cleaner, loop in double was
# removed and the abskey is set in frame 1
# only . This solves an other deform problem .
# -- if user does not want an autosaved image,
# the "no replace" option leaves the render
# window on the screen
#
# 0.2.7
# -- minor correction on line 147: "!=-1" added
#
# 0.2.6
# -- Creation of LAMP object is removed and replaced
# by the use of the shadeless option in material object
#
# -- helpmsg corrected : the aim of the script
# is to bake any type of textures so we have not
# to mapinput its textures on UV .
#
# --'pers' camera was replaced by an 'ortho' one.
#
# 0.2.5
# -- if a image file with the same name exits the
# system returns an error
#
# 0.2.4
# -- a LIMIT variable is added to unlock the uvcoords
# autoframing
#
#
# 0.2.3 :
# Great thanks for Apollux who sees a lot of these
# problems
#
# --Everytime you run the script a new set
# of objects is created. File size and memory
# consumption can go pretty high if you are
# not aware of that .
# Now it ONLY creates 3 objects: a flattened
# mesh, a camera and a lamp.
# --all the 3 objects was placed on layer 1, but if
# that layer was not visible while you used the script
# all you will get a is an empty render.
# Now the layer is tst and activated befor the shoot
# --The flattened mesh was really flattend only after
# frame 100 (if you playbacked the animation, you can
# actually see the mesh becoming flat on the first 100
# frames). No more.
# -- When the script is run, it changes temporary to
# the new cammera, set the render output to a square
# (i.e. 1024 x 1024 or else), does the render, and then
# resets the render output and the active camera to the
# original one. But if no original camera was found
# this produce an error.
#
# 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.
