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:

Spoiler: Show


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 window, if not

then repeat step 4.

Step 7: In that data window that appears check the box by double clicking the main mod and also check EVERY ESM (Main game DLCs and mods) And after that select "MyNavmeshCompatibilityPatch" and click "Set as active file".

Step 8: Be sure the top of the GECK window shows "My Navmesh Compatibility patch" as the main file, if it does not or has the name of some other file then close the GECK without saving and repeat step 7.

Step 9: After the GECK is finished loading, click on "Navmesh" at the very top of the GECK and select "Force Finalize All Spaces" and wait. The GECK window will likely say "Not Responding" but DO NOT close the window and just wait patiently. (This process for most modern systems will take about 10 to 20 minutes and even up to an hour for weaker hardware or for a large numbers of mods).

Step 10: Save the plugin and close the GECK. Be sure the plugin is active and below all other ESMs and have fun enjoying the game.



TIP: Load order can be changed after the patch is generated (Mod load order matters for the GECK), for example YUP loads after my mod but might end up loading after some mod that conflicts with YUP that is supposed to load before my mod, in such case you can change the load order around after the patch is generated as long as the patch is loaded as low as possible in your load order.


TIP 2: To find out if mods you have need to be added to the patch creation process you can load all your mods in xEDIT right click and apply a filter and check "By record signature" and "Navigation Mesh". Also you can consult the lists down below for mods you may have in your load order.


WARNING: Load order must be set before the patch creation process, failing to do so may result in improper changes being applied.


WARNING 2: Ultimate Edition ESM Fixes MUST be disabled before creating a patch (For TTW use MO2 to hide all of the TTW ESMs that replace vanilla NV ESMs in the filetree tab), will cause in game crashes if a patch is generated with it enabled. (You can reenable the ESMs later after patching)


WARNING 3: The patch must be regenerated every time you update this mod to a new version and always from a clean ESM file. A clean file should also be used any time you need to regenerate the patch.


WARNING 4: Do not generate and use more than one patch at a time (This includes my pregenerated YUP patch and the VNV navmesh patch) , all mods that add load doors and navmeshes to vanilla worldspaces should be loaded at the same time in the GECK.


WARNING 5: If you are using mods that alter navmeshes that are an ESP that is NOT flagged as an ESM in xEDIT then it is highly recommended you uninstall and stop using said mods or contact the mod author and tell them to make the ESP an ESM. Mods that do this will cause severe pathfinding issues and game breaking glitches even when not using this mod.


WARNING 6: Don't load any ESPs in the GECK while generating patches (ESM flagged ESPs can be loaded).


WARNING 7: Disable Special K, ENB and other similar mods before launching the GECK or the GECK could crash.
