-//HelloAt the moment, this isn't workingIt seems there is an issue with Skyboxes in Amnesia - as instead of showing ​the skybox ​in wholeit only shows one sideThe same results are returned when making a Skybox with a different type of base (Vertical Crossinstead of vertical strip, for example).\\ +===== DevelopersRead! =====

You __DO NOT__ need this file if your //Amnesia: The Dark Descent // version is not 1.3.1. Optionally include the file when exporting your Custom Story or Full Conversionhowever have a readme ​or note as to why DevIL.dll is included out of courtesy to the user

 +Skyboxes may show incorrectly depending on which Amnesia version a user plays on.
  
-<​note>​As of Amnesia'​s 1.3 release, the method in which the game reads Skyboxes has changed slightly, \\ 
-noticeably in orientation and raw image layout. Should the Skybox issues be fixed, this will be rewritten.\\

-The Skybox you'll be making if you are using the above website will likely be constructed using five raw images of 512×512 dimensions. This isn't much of a dilemma, since while there are five images, the '​missing'​ section is //Bottom//, which you can simply make a 512×512 square of a color (I tend to use RGB=128 ​Grey, but it is completely optional).+The Skybox you'll be making if you are using the above website will likely be constructed using five raw images of 512×512 dimensions.

-Another option is to double the dimensions of your images (so in this case, 1024x1024, making a 6144x1024 ​sized skybox).

-Done, at least, with the Photoshop tutorial. I'll look into alternative methods.+{{http://​puu.sh/​hQ3z2/​807c7e7380.jpg?​direct&​600}} 
 + 
 +Done
 + 
 +===== What else can I do with a Skybox? ===== 
 + 
 +==== Creating Skyboxes with different Basemaps ==== 
 + 
 +Some Skyboxes are great. Instead of requiring construction in Photoshopthey are already set out in a format which looks great to other Skybox building applications. What we made earlier by placing the six images side by side was called a Horizontal strip. 
 + 
 +{{http://​www.cgtextures.com/​tutorials/​cubemaps/​images/​cubemap_layouts.gif?​direct&​}} 
 + 
 +As you can seethere are many ways to create a Skybox. [[http://​developer.amd.com/​tools-and-sdks/​archive/​legacy-cpu-gpu-tools/​cubemapgen/​|AMD/​ATI'​s application CubeMapGen]] is able to load vertical cross images, which you can find on the internet and even assemble yourself ​with enough practice. CubeMapGen is also able to preview ​the Skybox, and export .dds images in a similar way the NVidia Tool does in Photoshop
 + 
 +{{http://​puu.sh/​hRHHW/​014f9dc5ec.jpg?​direct&​800}} 
 + 
 +There are likely other methods, but I won't go too in-depth with those. 
 + 
 +==== Raising my horizon ==== 
 + 
 +As we can see above in CubeMapGen, the horizon, or rather, the moment the grey bottom meets the sides of the cubemap is quite low. As such, it looks unrealistic when viewing from the edge of your walkable map boundary. In Photoshop, raising the horizon is rather simple! 
 + 
 +=== Step 1: Have your Horizontal Strip ready. === 
 + 
 +The easiest way to do this is to do so with a Horizontal Strip, or the same format as explained by the above tutorial. 
 + 
 +{{http://​puu.sh/​hRIst/​76954162a1.jpg?​direct&​800}} 
 + 
 +am using a different skybox to the previous tutorial, since you can use just about any skybox, as most horizons are in the approximate middle of the cubemap. 
 + 
 +=== Step 2: Color === 
 + 
 +Create a Layer and push it all the way to the bottom and color it something like grey. This will serve as your bottom tile of your basemap, and when you delete parts of your skybox, the grey color will appear and remain the same, allowing the blend from the sides of the map and the bottom to become even lesser noticeable. 
 + 
 +{{http://​puu.sh/​hRJ6d/​84e4df9120.jpg?​direct&​800}} 
 + 
 +=== Step 3: Select and Delete === 
 + 
 +Use the Rectangular Marquee Tool to select the entire bottom half of the image. Be default, that tool is the second from the top of Photoshop's Tools window, and is shaped like a square with a few openings between the outline. 
 + 
 +Starting slightly outside the image on the left side, click, hold and drag to the bottom right corner of the image, effectively selecting the whole bottom half. Zoom in if you have to. 
 + 
 +{{http://​puu.sh/​hRJok/​1b125282b6.jpg?​direct&​800}} 
 + 
 +Now, select your Front from the layers window and then press the Delete key. It will remove the bottom half of your front. Now repeat by selecting your Back, Left and Right layers and deleting those. 
 + 
 +{{http://​puu.sh/​hRKmP/​90935ba4c3.jpg?​direct&​800}} 
 + 
 +=== Step 4: Export === 
 + 
 +Now just save as you would by following the earlier tutorial above. 
 + 
 +Here's how my Skybox looks. 
 + 
 +{{http://​puu.sh/​hRKP5/​5ab89283cd.jpg?​direct&​800}} 
 + 
 +Now we have a flat horizon, which hopefully will not be visible to the player. You can adjust the horizon point by lowering the amount of area which you delete. Just remember not to delete any part of the '​Top'​ image, as then you will have half a top on your skybox!

-Are you using an Amnesia version greater than the beta release ​titled //131111//? If so, Skyboxes currently appear to be brokenAs of now (15 May 2015), there is no solution to this issue, but I'll update when one comes up.+Are you using an Amnesia version greater than 1.3? If so, the problem is caused by a .dll file titled ​DevIL.dll which has been included with Amnesia since its release. Between 1.3 and 1.3.1, the source code changed slightly, breaking the skyboxes. [[https://www.dropbox.com/s/c2e7bi3k8f871ka/​DevIL.zip?dl=0|Download an older DevIL.dll file here]] ​(the same one included with 1.3), and you should not have any issues. Include it with your Custom Story or Full Conversion export if necessary, but notify the user as to why it is included. A readme in the least should suffice.
