Setup Mantella and xVaSynth

Requirements for the AI mods

For Mantella to work we need a few things set up.

1. xVaSynth - Contains voice files and lip animations
2. Mantella Program - Connects your voice with the NPCs using GPT and other ML models.
3. Mantella Spell - Lets you decide when to trigger to Mantella function in game.

All of these 3 mods must be active for the mod to work. In FUS and Auriel's Dream we will only support the use of GPT. If you want to use local models instead, then you can try this out but we will not give advice this as the performance will heavily depend on your hardware and not something we can replicate.

Step 1 - Insert your GPT key into the Mantella file

As seem in the screenshot, just pase in your GPT key. Make sure there is no trailing spaces at the end of the key. Double click on "Mantella Software" in MO2, that will open a new window. Here you can see a file named "GPT_SECRET_KEY.txt", right click on this and click "Open". This will then open in the text editor you have set up. In here, paste in your GPT key, save and close the file.

Step 2 - Activate the 3 mods

Activate the three mods we mentioned in the intro in the "AI Mods" category.

Step 3 - Reinstall xVaSynth with MEREGE option

Unfortuntly we have not yet found a solution to bypass a wabbajack issue with installing this correctly for users, so some extra steps are required.

3.1 Reinstall xVaSynth (with MERGE option)

Follow these steps very very carefully. Do not mess up step 7.

1. Tick the "Hidden Files" box so it becomes blue.
2. Search for "main app", that should now display 1 item.
3. Right click on it and choose "Install".
4. A Window will pop up. Here you must right click where it says "3.0.0" and choose "Set as directory"
5. Click OK.
6. Click ignore on the popup that says "This mod was probably NOT setup correctly". We have done it correctly.
7. Most important step, choose the "Merge" option. If you by accident choose "Replace" then you will loose all the voice files and you will need to reinstall the modlist then start setting up this from scratch.

3.2 Reinstall xVaSynth patch (with MERGE option)

Follow these steps very very carefully. Do not mess up step 5.

1. Search for "v3.0.2", that should now display 1 item.
2. Right click on it and choose "Install".
3. A window pops up, just press OK.
4. Another window pops up, press ignore.
5. Most important step, choose the "Merge" option. If you by accident choose "Replace" then you will loose all the voice files and you will need to reinstall the modlist then start setting up this from scratch.

Now all the risky things are done, and just a few more easy steps to go.

Step 4 - Configure xVaSynth

After having reinstalled xVaSynth, you now need to configure it.

1. Double click on xVaSynth

2. Right click on xVaSynth.exe and choose "Execute with VFS"

3. Press "Esc" on the keyboard to get rid if the popup.

4. Click on the æ icon in the top right

5. Now click on CMUDict in the top left.

6. Next, click on the "Enable all" option in the bottom left.

7. Click save in the bottom right.

8. Press Close on the popup, then press Esc on the keyboard to close the æ window.

9. Click on the jiggsaw icon in the top right (Plugins).

10. Now tick the checkbox to enbable ".lip and .fuz file maker"
11. Click apply in the bottom right.

12. Press Close on the new popup, then press Esc on the keyboard to close the Plugins window.

That is all the required setting complete. You can now close the program.

Now, everything is installed and ready to use.
