#Description:
# This script is a texture changer in any animation. This accesses the textures in a materials
#channels and changes the texture in that channel depending on the frame number.
#
# This is perfect for animations using textures. This could be adapted for Games easily by
#incorporating the script to run from commands.. i.e, you could have it so that when a character
#'talks' in game, it would run a precompiled sequence of textures from this easily. This could
#be adapted for editing UV maps easily.
#
# Currently this is built in such a way that you need to have Textures set up prior to this script
#as this would do better for gaming and such and you dont need to reload images from files, but instead
#from memory. This does mean a little bit of setup time, but the code could be easily changed that instead
#of switching textures, you can change the filename instead the base texture and reload.
#
# I added in the feature that you can animate more than 1 object at a time, you just need to fill
#out the list correctly with more lists of channels, which is easy.
#
# This was built out of a need to easily and quickly change textures on a material on certain
#frames, in particular for a face composed of channels with a channel for eyes, a channel for
#the mouth, 1 for eyebrows, etc.
#
# Updates since version 0.7:
# Corrected a glitch in the code which selects a channel.
# Updates since version 0.8:
# Corrected a glitch in the code which selects a material in a mesh.
#
#
# Limitations of this version:
# The channels need to be preoccupied in a material first for this to work, but, you dont need
#to have all the channels filledto use the script, only the ones you need to change need to
#have something in there first.
#
# Only allows you to change the 9 channels on a single material so far, which i guess is
#already the limit in blender per material anyway, so it doesnt matter.
#
# There seems to be a flaw in Blender that the script doesnt change using a FrameChanged link
#unless the material tab is open using Alt-A and having blender game GLSL materials active.
#This still works using Anim, previewing requires the material panel open for this to work.
#Usage:
#Edit the channel information below. examples are given above the channels. There is no limit i believe
#on how many changes you can put for a channel.

######################################################
#Objects, Materials, Textures and the details needed to change the texture over time.
#Here are 2 examples, these are useable if you just take out the leading hashes.
#Example 1:
#1 object being changed called "TNenfaceTex"(a face as you can tell), 1 material being
#changed called "TToonSkinTex1" in the object (not necessarily material 1 in the object, the materials
#are all searched in the object). 4 channels are being used in this material, only 2 are animated
#with something.
#
#channels 1 and 6-10 are either non-animated textures or empty in the material.
#
#channel 2's texture uses the texture "TFaceNoseBase" for the all of the animation. This
#doesn't change.
#
#channel 3's texture uses the texture "TFaceMouthBase" for the bulk of the animation. This
#changes to "TFaceMouthSmirk" at frame 100 for 10 frames (until frame 110). At frame 110, it
#changes back to the base texture "TFaceMouthBase" and stays that way until the end of the animation.
#
#channel 4's texture uses the texture "TFaceEyesBase" for the bulk of the animation.
#This changes to "TFaceEyesHalfopen" at frame 25 for 5 frames (until frame 30).
#At frame 30, it changes to the texture "TFaceEyesClosed" for 10 frames (until frame 40).
#At frame 40, it changes back to "TFaceEyesHalfopen" for 5 frames until frame 45.
#At frame 45, it changes back to the base texture "TFaceEyesBase" until the next change (at frame 75
#as seen in this example). This channel creates several 'blink' style animations easily.
#
#channel 5's texture uses the texture "TFaceEyeBBase" for the all of the animation. This
#doesn't change.
#
#Code:
#
#MaterialChannels=[
#[["TNenfacetex","TToonSkinTex1"],
#[["",1]],
#[["TFaceNoseBase",2]],
#[["TFaceMouthBase",3],["TFaceMouthSmirk",100,10]],
#[["TFaceEyesBase",4],["TFaceEyesHalfopen",25,5,35,5,75,5,85,5,115,5,125,5],["TFaceEyesClosed",30,10,80,10,120,10]],
#[["TFaceEyeBBase",5]],
#[["",6]],
#[["",7]],
#[["",8]],
#[["",9]],
#[["",10]]]]
#Example 2:
#2 objects are being changed. first is called "TNenfaceTex"(a face as you can tell), 1 material being
#changed called "TToonSkinTex1" in the object (not necessarily material 1 in the object, the materials
#are all searched in the object). 4 channels are being used in this material, only 2 are animated
#with something. channels 1 and 6-10 are either non-animated textures or empty in the material.
#This first material animation is identical to above.
#Object 2 is called "TNenHair", of which 1 material is changed called "TNenHairMaterial". In this
#material 2 channels are being animated, channels 3-10 are not being used.
#
#channel 1's texture uses the texture "THairFringeBaseTex" for the bulk of the animation. This
#changes to "THairFringeShinyTex" at frame 200 for 50 frames (until frame 250). At frame 700, it
#changes to "THairFringeDullTex" for 600 frames (until frame 1300).
#
#channel 2's texture uses the texture "THairLongHairBaseTex" for the bulk of the animation. This
#changes to "THairLongHairShinyTex" at frame 200 for 50 frames (until frame 250). At frame 700, it
#changes to "THairLongHairDullTex" for 600 frames (until frame 1300).
