FSX implements a new method to reduce the -
<br>
* Amount of disk-space required to create aircraft containers.
* Processing & memory overheads incurred by loading & unloading identical textures from different repaints.
* Minimize the texture load impact for the multi-player environment.
'''N.B.''' 
<br>
It is important you understand the impact of missing textures, or mis-matched texture file extensions.
<br>
Please first read - '''[http://www.fsdeveloper.com/wiki/index.php?title=Texture_-_Missing_(FSX) Texture - Missing (FSX)]'''
<br>
== Overview ==
=== Pre FSX ===
Every aircraft repaint required a full complement of the model's textures to be present in every texture livery folder.<br>
There was a basic fallback option, utilising the '''FS\texture''' folder for textures common across all aircraft & scenery.

=== In FSX & Later ===
FSX and later utilise an enhanced ''Texture Fallback Scheme''.<br>
In its most basic form, an aircraft model only requires a single folder containing all that model's textures.<br>
This folder is that aircraft's '''default texture fallback folder'''.

Each livery's repaint folder then need only contain those textures ''different'' from the default.<br>
'''Plus''' a text file named '''texture.cfg''', and that livery's '''thumbnail.jpg'''

'''NB'''

==== texture.cfg ====
The texture config file contains references to the relative paths of the various fallback folders.<br>
These references are ranked in order of fallback #.<br>
'''Fallback.#=''' supplemental texture directories outside of the current livery's texture folder

The standard texture.cfg files have 3 fall back paths,<br>
but can cascade any number of fallbacks listed.<br>
e.g. The FSX Acceleration FA-18 uses additional fallback.# lines.

A copy of the '''texture.cfg''' is placed in every livery's texture folder.<br>
Fallback texture files do not override textures found in the texture folder originally being called.

==== thumbnail.jpg ====
A small image of that aircraft livery for display in the select aircraft dialog.

The required format is a 256x128 pixel jpg.

== Bugs ==
There are a couple of minor issues -
# An acknowledged 'bug' that ''sometimes'' causes FSX -
#* To lose track of where common textures are located.
#* ''thumbnail.jpg'' images to become ''out of synch'' with their parent folder.
#* Multiplayer users to sometimes see other player's, or their own, aircraft displaying incorrect liveries, (generally the fallback livery).
#* To display some legacy aircraft incorrectly, as their texturing depends on accessing default files
#*: e.g. '''GlobalEnv_*.dds'''
#*: which by default are located in -
#*: '''C:\Program Files\Microsoft Games\Microsoft Flight Simulator X\Texture'''
# An incorrect path error in the FSX default aircraft's '''fallback.3''' reference, (varies with some models [[#fallback.Z|see below]]), where paths refer to an MS 'development folder', i.e. not present on a user's system.

Inclusion of an appropriate '''texture.cfg''' will correct these.

=== Fix - Overview ===
The ''solution'' for all models is to -
* Use the '''..\texture''' folder only for ''common textures'', (a full texture set).
i.e. This '''default texture fallback folder''' must not be called directly from any [fltsim.N] texture= entry.
* And for '''every''' livery -
** Have dedicated '''..\texture.variation''' folders contining only the unique textures.
** Correct the '''texture.cfg''' file to utilise the correct fallback paths.

=== Fix - For Existing Models ===
To fix this issue for pre-existing 3rd party, or FSX default aircraft.<br>
For the sake of simplicity only, in the following example I've used the numbering system adopted for FSX default aircraft.
===== Folder Structure =====
The aircraft folder structure should be -
<pre>	..\texture
		all common textures, (including those for the 'default livery')
		texture.cfg
	
	..\texture.0
		contains no textures, (default livery is held in ..\texture)
		texture.cfg
		thumbnail.jpg
	
	..\texture.1
		livery 1 unique textures only 
		texture.cfg
		thumbnail.jpg
	
	..\texture.2
		livery 2 unique textures only 
		texture.cfg
		thumbnail.jpg</pre>
The additional folder '''..\texture.0''' acts as the unique livery reference for that livery previously referenced by '''..\texture'''

===== aircraft.cfg =====
Generally, in the '''aircraft.cfg''' this was accessed by -
<pre>	[fltsim.0]
	texture=</pre>
Which would now become -
<pre>	[fltsim.0]
	texture=0</pre>
I said generally, as some default FSX aircraft have non-rational numbering applied.

===== texture.cfg =====
Example below corrects the reference for FSX default aircraft's fallback.3 path.
<pre>	fallback.1=..\texture
	fallback.2=..\..\..\..\Scenery\Global\texture
	fallback.3=..\..\..\..\Texture</pre>
'''Warning''' - <br>
FSX Acceleration's FA-18, and other 3rd. party aircraft use additional fallback.# lines.<br>
You should edit those aircraft's texture.cfg files manually. 

[[#fallback.3|Also see fallback.Z below]].

==== fallback.Z ====
The last row is the path to FSX's root Texture folder,<br>
e.g. fallback.Z=..\..\..\..\Texture<br>
Where '''Z''' generally is '''3''' 

In this example, fallback.Z provides a valid path to the following common textures -
     Fresnel_Ramp.dds
     FresnelTest.bmp
     FresnelWater.bmp
     GENFresnel.dds
     GlobalEnv_AC_Chrome.dds
     GlobalEnv_AC_Chrome_32.dds
     GlobalEnv_AC_Chrome_64.dds
     GlobalEnv_AC_Chrome_128.dds
     GlobalEnvTest.dds
