LOD Guide

Before getting started, there are a few things you should know. First, generating LOD is not a requirement, but it will add detail in the distance by improving terrain geometry and the amount of things that have LOD, thanks to the resource mods listed below. It becomes a requirement if you installed texture mods that affect objects in LOD or terrain, or if you are using a mod that requires LOD to be generated because of terrain edits. Terrain LOD creates a much larger file size and will increase the amount of time it takes to run xLODGen. This guide does not need new terrain LOD, so only object LOD will be generated. If you need new terrain LOD the instructions will be the exact same except enabling Terrain LOD option in addition to the Object LOD option.

Installing xLODGen

1. Download the latest xLODGen file from here.
2. Once the download has finished, extract the contents of the archive to any location of your choice.
3. In MO2, select the button at the top of MO2 to open the executables menu.
4. Click the + at the top of the window and the select Add from file...
5. From the pop-up, navigate to where xLODGen is installed and select xLODGen.exe.
6. In the Arguments box in the right pane, enter -FNV -O:"C:\Output\"

This argument will make the files generated through xLODGen appear in a folder called Output on your C:\ drive (the drive Windows is installed on). You can change this path to whatever you would like if you would prefer the files to be generated elsewhere (Not a UAC protected folder or the game folder).

9. Select Apply then OK.

Installing LOD Resources

• FNVLODGen Resources - Main File - FNVLODGen Resources
• If you are using NMCs Texture Pack, also install the Optional File - NMC LOD texture fix file.
• LOD Additions and Improvements - Main File - LODadditions
• Only if you use NMCs Texture Pack: Much Needed LOD - JUST the Optional File - Much Needed LOD - NMC Patch.
• LOD Texture Patches - Main File - NMC LOD Patch and/or Main File - Poco-Ojo LOD Texture Patch (Depending on which texture mods you are using.)

Running xLODGen

1. Select xLODGen from the executables drop-down in the top right of MO2 and click Run.
2. Once the program has loaded, right-click in the left pane and click Select All.
3. In the right pane, check Objects LOD but leave Trees LOD unchecked.

Tree LOD is not functional in New Vegas. LOD for trees is covered in Object LOD.

4. Under the Objects LOD section, change the Atlas size option to 8192 x 8192.
5. Click Generate.
6. When complete, the log will stop and at the end you will see a message saying "LOD generation complete", you can now close xLODGen.

Installation

1. In MO2, right-click on the Overwrite folder at the bottom of the left pane and select All Mods -> Create empty mod above.
2. Title the mod FNVLODGen Output.
3. Navigate to where the LOD files were generated and select both the textures and meshes folders.
4. Cut them to the FNVLODGen Output mod you just created (Right-click on the mod and select Open in Explorer).
