NPV: Creating a custom NPC

Summary

Created by @manavortex Published May 13 2023

This page is a part of the NPV guide. It will show you how to use the provided example project to create a custom NPC for Cyberpunk 2077, whom you can then spawn with AppearanceMenuMod.

Skipping and skimming

This guide contains as little fluff as possible. Extra information

The .lua file

We're registering our NPC with AppearanceMenuMod via a .lua file, which needs to end up in AMM's Custom Entities folder. The full path in the Cyberpunk directory will be this:

bin\x64\plugins\cyber_engine_tweaks\mods\AppearanceMenuMod\Collabs\Custon Entities

I have prepared two example files in the Wolvenkit's project's resources. Delete the one that you aren't using, then let's take a look at the other one:

tutorial_custom_female_character.lua

tutorial_custom_male_character.lua

The file structure

This is the file content for the female example:

return {
  -- Your beautiful name :)
  modder = "tutorial",

  -- This must be UNIQUE so be creative!
  -- NO SPACES OR SYMBOLS ALLOWED
  unique_identifier = "tutorial_female_character",

  -- This is the info about your new entity
  entity_info = {
  -- name: The name that will be shown in the Spawn tab
    name = "Tutorial Woman",
  -- path: The path to your entity file. Must use double slash bars \\
    path = "tutorial\\npv\\your_female_character\\ops\\your_female_character.ent",
  -- record: This is the TweakDB record that will be used to add your character. More information below.
    record = "Character.afterlife_merc_fast_melee_w_hard",
  -- type: Character or Vehicle
    type = "Character",
  -- customName: Set this to true if you want the name you set here to appear in AMM Scan tab.
    customName = true
  },

  appearances = {
    "tutorial_woman_casual", 
    "tutorial_woman_business", 
  },  

  -- Here you can pass a list of attributes from different records to be copied to your new character.
  -- More information below.
  attributes = {
  },
}

It loads our root entity from tutorial\npv\your_female_character\ops\your_female_character.ent. That's the file which tells the game what to load.

The root entity

You find the root entity for your character here:

tutorial\npv\your_female_character\ops\your_female_character.ent
tutorial\npv\your_male_character\ops\your_male_character.ent

The root entity hooks up your .app file and the appearance names in the .lua file, and that's about everything there is to say about it. Here's how it looks:

Let's look at the .app file now.

The app file

This section will tell you how to edit your NPV's appearance – their skin colour, chrome, piercings, tattoos. We will do this in the .app file.

This is where all of your NPC's appearances are defined (appearanceDefinition, linked to the root entity via name). The appearanceDefinition's components define your NPV's properties, pulling in equipment, facial expressions, hair and skin.

It looks like this:

How do I know what to put?

To find out which variants and appearances to use, I suggest that you use NoraLee's excellent NPV Part Picker. It will look like this:

Customizing Cyberware

When selecting a different cyberware than the preconfigured one, you have to set the appearance name, or the whole thing will show up in grey. The appearance names are usually identical to the cyberware (cyberware_01, cyberware_02 etc.), but if you are uncertain, you can also open the mesh file and check the appearances list at the top.

Customizing piercings and chrome: Chunkmasks

You have the full piercing or cyberware file, but you're only using parts of it — yet the game stubbornly shows you the whole mesh.

Fortunately, you don't have to edit it in Blender, because you can hide the parts you aren't using via chunkmasks. Find the piercing or cyberware component in your .app file:

How do I know which numbers to put?

You can see that inside the .mesh file (which you can see in the component's depotPath). Open it in Wolvenkit, then switch to the Mesh Preview tab and toggle the checkboxes on the right; those directly correspond to the boxes you need to uncheck in the .app file:

To hide those bits in the .app, we simply need to uncheck the corresponding boxes - check the previous screnshot!

Hair

This section will teach you how to add another hair mesh to your NPV. We will first remove the default hair, then replace it with the one you want.

1. Delete the current hair from the .app — there should be 2-3 components, their names will start with either hair_ or hh_0

2. Find the correct hair mesh. You have three options for this:

   1. Looking it up on our nifty list

   2. Using NoraLee's NPV Part Picker

   3. Filtering the files and clicking through their previews: female: base\characters\common\hair > wa_ > .mesh > !shadow male: base\characters\common\hair > ma_ > .mesh > !shadow

3. Enter the name of the hair mesh that you want to use into the Asset Browser's search bar (see next screenshot) and hit Return.

4. Once you have found the correct mesh file, right-click it and select "Find Files Using This":

1. This will give you a list of files, which you can mostly ignore. The only thing we care about is the hair's .ent file:

   
2. Open the .ent file and expand the components array. You will find three components in there, which you can now copy over to your .app!

   

And that's the gist of it!

Go forth and create custom apperances!

You can check this guide, or look through the .app files for other NPCs for ideas. If you need further details, I highly recommend checking out NoraLee's much more detailed tutorial, which will also give you all the context you could possibly need.
