Mod Installation Advice
When following this guide, I strongly advise following it to the letter. For the sake of your sanity, please don't run LOOT until you reach the finishing line. If you run it before you are instructed to do so, you will find that it throws numerous errors. These errors will be fixed later in the guide.
Note for Special Instructions sections.
Throughout the guide, you will find many places where you are instructed to remove files with a * in the path. For example, helgen reborn.esp\*.tga. In these cases, the asterisk means to delete all files matching this pattern.
A Note On Extracting BSA Files
This guide recommends only extracting BSA files if they are distributed with a dummy plugin or as part of a merge.
To extract a BSA, you will use the BSA Extractor plugin included with Mod Organizer 2. Enable the plugin by following these steps:
Click the "spanner and screwdriver" icon in the top left corner of MO2.
Click the Plugins tab.
Find and select the BSA Extractor plugin.
On the right side, double click the Enabled option and set it to True.
At this point, you will receive a notification during installation for any mod that includes a BSA asking if you want to extract it. If the instructions tell you to do so, click Yes otherwise, click No.
A Note On Converting Old Plugins
Throughout the guide, a few plugins are using the old form 43. These plugins must be converted in the Creation Kit (CK) to work in this guide.
Mods that require converting will show this tag: CONVERT
When converting mods through the Creation Kit, some will have masters that are ESPs, but the CK requires these to be ESMs or flagged as ESMs. Convert these plugins through the following process:
Converting the plugin with the Creation Kit
Ensure the Overwrite folder is empty.
Run the CK from the executable drop-down menu.
Select the File menu and choose Data....
Find the plugin to be converted and select Set as Active File.
Note the Parent Masters listed and ensure they are checked (double-click the plugin listing to check it).
Click OK and allow the CK to load.
Once complete, save the plug (File→Save).
Close the CK.
The plugin is automatically saved over the older non-converted version.
Verifying the plugin with SSEEdit
Run SSEEdit from the executable drop-down menu.
Right-click in the plugin pane and choose Select None.
Double-click on the plugin saved from the steps above and allow SSEEdit to load until the log says, "Background Loader: finished".
Right-click on the last plugin in the left pane (it should be the new plugin), and select Check for Errors.
The check should come back clean reading, "All done!". If there are errors, you will have to correct them before continuing to the next step.
Right-click on the plugin again and choose Sort Masters.
The last step is to run SSEEdit Quick Auto Clean on the plugin.
Close SSEEdit and be sure to save the modified plugin.
A Note On Cathedral Assets Optimizer
Throughout the guide, there are a few mods that use meshes and textures designed for classic Skyrim. These mods must be processed using Cathedral Assets Optimizer to work with Skyrim Special Edition. For these mods, use the following instructions to perform the conversion:
Close Mod Organizer 2, as CAO is designed to run outside of MO2.
Launch Cathedral Assets Optimizer.
Click the Open Directory button and navigate to the folder containing the mod requiring conversion.
Select either the LOTD Plus - BSA or LOTD Plus - No BSA profile depending on what is listed under Special Instructions
Mods that require converting will show this tag: CAO
