You'll also need to fire up New Vegas through Steam or GOG the regular way once for xNVSE's loader to work. I recommend making a shortcut of this file and putting it on your desktop. NOTE: For xNVSE to take effect, you'll need to launch New Vegas with the nvse_loader.exe file that comes with this mod. The download page has installation instructions. This mod extends the scripting capabilities of the vanilla game, which is necessary for making many popular mods work. Next up, you'll want the newest version of the New Vegas Script Extender, or xNVSE. The location name Colusa/Nevarro is listed in game scripts. Navarro is based on the real world location Navarro, California, located 10 miles (16 mm) from the Pacific coast. If desired, you can override LOOT's optimization to make manual tweaks to your load order yourself (this shouldn't be necessary for the mods in this list). Navarro appears only in Fallout 2 and is mentioned in Fallout 3, Fallout: New Vegas, Lonesome Road, and the Fallout Bible.

This program automatically reorganizes your load order to make it as stable as possible. A great tool to pair with your mod manager is the Load Order Optimization Tool, or LOOT. This will allow New Vegas to read and accept any texture mods you install (we'll get to those later). Then go to Settings > Workarounds > BSA Redirection and toggle it. After installing it, log in, and select New Vegas as the game you're modding. I highly recommend Vortex since it has a great UI and is very easy to use. These tools automatically handle most mods' installation, so you don't have to dig around in-game files - simply drag-and-drop compressed mod files, and the mod manager will do the rest. The first thing you need is a Nexus Mods account, the website where most mods are posted.
