📋 About This Mod

Features:

Compatible with most mods that edit navmeshes.

Better pathing, seeks to eliminate NPCs walking into walls and other objects.

More competitive AI, more cover for NPCs to use and better navigation for melee attackers so they don't take long paths to get to you.

Fixes vanilla game navmesh errors.

Fixes sunken nodes which can lead to NPCs being stuck in the ground.

Fixes unfinalized cells and mismatched borders that prevent NPCs from navigating.

Optimized vanilla navmeshes for performance.

Compatibility:

This mod is compatible with most mods that contain navmeshes aside from mods that contain deleted navmeshes or navmeshes in ESP (Recommended to avoid those sorts of mods as they can cause crashing and game breaking glitches). For those who care enough to get maximum

compatibility you may want to use the patching guide below but it's no longer critical. DO NOT use "Navmesh Fixes and Improvements"

or other mods that try to fix vanilla game navmeshes with this mod, they will be redundant with this mod as it supersedes them.

Making A Custom Patch:

The following guide will show you how to use this mod properly with most mods that alter the vanilla landscape and is meant to be easy to follow even for casual players: WARNING: It's important you read the mod list at the bottom of the page and set load order BEFORE the patch creation process (Load order tells the GECK how to generate the patch) you can rearrange your load order after you are done. Also disable Special K before following the guide.

Here is an easy to follow video tutorial for making navmesh patches:

If you are having trouble following the video the written steps for making a patch are here:

Step 1: Download and install the "Blank Compatibility Patch" in the "Optional" section of this mods files on Nexus, DO NOT rename the file.

Step 2: Put the blank mod you downloaded as low as you can in your load order in Mod Organizer.

Step 3: Disable "Ultimate Edition ESM Fixes" if you have it installed (You can reenable the mod later after patching, failing to do so will causes crashes in game)

Step 4: Download the NV GECK from Steam(included with GoG version by default) and GECK Extender (Download BOTH main Geck Extender files on Nexus) and xNVSE (If you already installed xNVSE for use with other mods then no need to download it again).

Step 5: Go into the Mod Organizer ini editor and open "GeckCustom.ini" In the "General" section of the ini set bAllowMultipleMasterLoads=1 and then save and close the ini. (You may need to add the lines yourself).

Step 6: Launch the GECK (Construction Kit) through Mod Organizer and ensure it says "GECK Extender" at the top of the program
