There is a newer version of the mod available as a Synthesis patcher:  https://github.com/Jampi0n/Skyrim-LoadingScreenGenerator
You can find it on Synthesis by searching for "loading screen generator".




An easy to use xEdit script to create loading screens based on images in a selected directory. Can create a fully working loading screen mod from your favorite images, wallpapers and screenshots in a few seconds.

GitHub: Skyrim-LoadScreenGenerator


Installation:

1. Install the latest version of xEdit.
2. Download this mod and place the files in the 'Edit Scripts' folder of xEdit.
3. Run the script named 'JLoadScreenGenerator.pas' in xEdit. It does not matter which record you select, when running the script.
4. A dialog should open. Select the source directory and adjust settings to your liking. Make sure the aspect ratio is correct. Click on OK.
5. Wait until it's done.


Screen and Image Resolution:

In short: Works with any screen and image resolutions. Default settings should create the best results.

Loading screens must be adjusted to the aspect ratio of the screen. The script creates the loading screens for a certain target aspect ratio. Make sure, that the target aspect ratio in the settings is the same as the aspect ratio of your screen. When you first run the script, it tries to detect the aspect ratio of your screen.

By default, if the image aspect ratio differs from the target ratio, there will be black bars in order to keep the aspect ratio of the image. This means, images will always look right (no stretching), regardless of their aspect ratio and the target aspect ratio.


Loading Screen Messages:

Loading screen messages can be added by including a .txt file with the same name as the source image. For example the loading screen for the source image "SourceImage.png" will have the loading screen message contained in "SourceImage.txt". If there is no .txt file, there is also no loading screen message. Only the first line of the .txt file is used, so write the entire message in the first line.


For Mod Authors:

There is a new advanced page, which allows you to set extra options and generate multiple versions (different aspect ratios, different frequencies, etc.) at the same time. If you use MO2 or a similar mod manager, the necessary files will be generated in your override folder, together with a python script. Run the script to create a fully working Fomod installer from the generated files. You need python 3.8 in order to run the script, but it might also work with older versions, e.g 3.7.
This feature is relatively new and not all options are tested, so please report any issues you have.
