Dynamic appearances: Understanding the process

How does the ancient magic work?

Summary

This page explains the files from ItemAdditions: Dynamic Appearances -> Generated files, what they do, and how they do it.

You will be able to change the template project just by following the steps, but if you want to make your own mods, then you're going to want to understand this.

Depending on how you learn best, you can also fuck around and try to understand the connections yourself. In that case, check Exercise 1: Create more records at the end of the section.

The yaml

For a general explanation of what the yaml file does, check The control file: yourModName.yaml. This section will only cover the differences between a dynamic and a regular yaml.

This file contains the biggest part of the dynamic magic.

This is your dynamic project's yaml file, minus any properties that aren't influenced by the dynamic appearances:

Items.manavortex_my_custom_shirt_$(base_color)_$(secondary):
  $base: Items.TShirt
  $instances:
    - {base_color: black, secondary: samurai}
    - {base_color: black, secondary: witcher}
    - {base_color: black, secondary: galaxy}
    - {base_color: white, secondary: samurai}
    - {base_color: white, secondary: witcher}
    - {base_color: white, secondary: galaxy}
    - {base_color: red, secondary: samurai}
    - {base_color: red, secondary: witcher}
    - {base_color: red, secondary: galaxy}
  appearanceName: my_custom_shirt_!$(base_color)+$(secondary)
  entityName: my_custom_shirt_factory_name
  localizedDescription: LocKey#my_custom_shirt_i18n_desc
  displayName: LocKey#my_custom_shirt_i18n_$(base_color)_$(secondary)
  quality: Quality.Legendary
  icon:
    atlasResourcePath: manavortex\my_archive_xl_item\my_custom_shirt\my_custom_shirt_icons.inkatlas
    atlasPartName: my_custom_shirt_$(base_color)_$(secondary)
  statModifiers:
    - !append Quality.IconicItem
    - !append Character.ScaleToPlayerLevel
  appearanceSuffixes: []
  statModifierGroups:
    - !append-once Items.IconicQualityRandomization
  placementSlots: OutfitSlots.TorsoInner

This section will explain how that works - except for the appearanceName, you will find that in The root_entity.

Record names

TweakXL will generate one record per entry in $instances, according to the rules that you're using in the item name. This happens via property interpolation.

The example above will generate three item entries by substituting $(property_name) with the value of the property from the entry. If that isn't clear enough, check the example and the resulting item codes at the end of the line.

Items.manavortex_my_custom_shirt_$(base_color)_$(secondary):
  $instances:
    - {base_color: black, secondary: samurai}  # Items.manavortex_my_custom_shirt_black_samurai
    - {base_color: black, secondary: witcher}  # Items.manavortex_my_custom_shirt_black_witcher
    - {base_color: black, secondary: galaxy}   # Items.manavortex_my_custom_shirt_black_galaxy
    - {base_color: white, secondary: samurai}  # Items.manavortex_my_custom_shirt_white_samurai
    - {base_color: white, secondary: witcher}  # Items.manavortex_my_custom_shirt_white_witcher
    - {base_color: white, secondary: galaxy}   # Items.manavortex_my_custom_shirt_white_galaxy
    - {base_color: red, secondary: samurai}    # Items.manavortex_my_custom_shirt_red_samurai
    - {base_color: red, secondary: witcher}    # Items.manavortex_my_custom_shirt_red_witcher
    - {base_color: red, secondary: galaxy}     # Items.manavortex_my_custom_shirt_red_galaxy

If you install and launch your project, you can immediately spawn them in Cyberpunk via Cyber Engine Tweaks:

Game.AddToInventory("Items.manavortex_my_custom_shirt_black_samurai")
Game.AddToInventory("Items.manavortex_my_custom_shirt_black_witcher")
Game.AddToInventory("Items.manavortex_my_custom_shirt_black_galaxy")
Game.AddToInventory("Items.manavortex_my_custom_shirt_white_samurai")
Game.AddToInventory("Items.manavortex_my_custom_shirt_white_witcher")
Game.AddToInventory("Items.manavortex_my_custom_shirt_white_galaxy")
Game.AddToInventory("Items.manavortex_my_custom_shirt_red_samurai")
Game.AddToInventory("Items.manavortex_my_custom_shirt_red_witcher")
Game.AddToInventory("Items.manavortex_my_custom_shirt_red_galaxy")

Display names

Like the record names, the displayName property is also generated for each entry:

displayName: my_custom_shirt_i18n_$(base_color)_$(secondary)
$instances:
  - {base_color: black, secondary: samurai}  # my_custom_shirt_i18n_black_samurai
  - {base_color: black, secondary: witcher}  # my_custom_shirt_i18n_black_witcher
  - {base_color: black, secondary: galaxy}   # my_custom_shirt_i18n_black_galaxy
  - {base_color: white, secondary: samurai}  # my_custom_shirt_i18n_white_samurai
  - {base_color: white, secondary: witcher}  # my_custom_shirt_i18n_white_witcher
  - {base_color: white, secondary: galaxy}   # my_custom_shirt_i18n_white_galaxy
  - {base_color: red, secondary: samurai}    # my_custom_shirt_i18n_red_samurai
  - {base_color: red, secondary: witcher}    # my_custom_shirt_i18n_red_witcher

These entries have been auto-generated in your localization file.

Icons

The icon name in the record is also generated for each entry. They are all using the same inkatlas, but you can generate that as well if you want - I've done it for the Netrunner suits, since I needed more than 100 icons.

icon:
  atlasResourcePath: manavortex\my_archive_xl_item\my_custom_shirt\my_custom_shirt_icons.inkatlas
  atlasPartName: my_custom_shirt_$(base_color)_$(secondary)
$instances:
  - {base_color: black, secondary: samurai}  # my_custom_shirt_i18n_black_samurai
  - {base_color: black, secondary: witcher}  # my_custom_shirt_i18n_black_witcher
  - {base_color: black, secondary: galaxy}   # my_custom_shirt_i18n_black_galaxy
  - {base_color: white, secondary: samurai}  # my_custom_shirt_i18n_white_samurai
  - {base_color: white, secondary: witcher}  # my_custom_shirt_i18n_white_witcher
  - {base_color: white, secondary: galaxy}   # my_custom_shirt_i18n_white_galaxy
  - {base_color: red, secondary: samurai}    # my_custom_shirt_i18n_red_samurai
  - {base_color: red, secondary: witcher}    # my_custom_shirt_i18n_red_witcher

You can see that the generated names are identical to the ones in the section Display names above. That is because the key to generate them (atlasPartName) has the same pattern as displayName .

If you want to make gendered icons, please check Gendered preview icons -> Does this work with dynamic variants?

Exercise 1: Create more records

This is outdated and needs to be re-worked to consider the new generated structure

With clever hook-ups in the mesh entity, you can set up your items so that they can be changed with a simple .yaml edit — that means, the user can switch out the ribbon colour without ever starting Wolvenkit!

We'll use that here to enable "hidden" appearances.

I have hooked up the example project to support two base colours:

black
white

and three ribbon colors:

red
blue
green

By editing the $instances block in the .yaml, you should be able to spawn 6 different shirt in the game without touching any of the additional files!

The root_entity

For a general explanation of the root entity, check root_entity.ent. This section will only cover the differences between a dynamic and a regular root entity.

This is where you enable the feature by adding the tag DynamicAppearance to the visualTagsSchema (the last entry in the file):

For dynamic appearances, your root_entity file will contain one entry. You can give every item its own root entity, or share a file across the mod.

The appearance name in the root entity corresponds to the appearanceName property in the .yaml without the variant:

You can leave the appearanceName blank. In that case, ArchiveXL will look for an appearance with the same name as the name attribute.

The .app

For a general explanation of the .app file, check appearance.app. This section will only cover the differences between a dynamic and a regular .app file.

For dynamic variants, components in the .app file will be ignored. You have to use a mesh entity.

.app file: Conditional switching

You can find more about this under Dynamic Appearances: fine-tuning visibility conditions.

You can define appearances for different circumstances by changing the appearance names. This will let you influence the mesh entity even further by e.g. hiding parts of the mesh via chunkMask. And the best part is: you don't even need to touch your root entity.

In the context of our example project, this means that you can define your appearances like this:

Appearance name

Explanation

app_file_dynamic_appearance

Your regular appearance. Is displayed when none of the conditional ones apply.

app_file_dynamic_appearance&camera=tpp

This is only active in third person perspective. The item will be completely invisible in first person.

app_file_dynamic_appearance&camera=fpp

This becomes active whenever you are in first person perspective. You'll usually want this to remove the mesh from your face via partsOverrides.

app_file_dynamic_appearance&gender=male

You shouldn't do this — instead, use Substitutions in the mesh file path.

The mesh_entity

Unless you are using .app file: Conditional switching, this file contains the entire magic. This section will explain how you tell the .ent file to load different meshes.

You can use either Substitutions or (not recommended) .ent file: conditional switching.

Wait, this is not what I want!

For a picture of the difference between substitutions and conditional switching, check The diagram 's bottom left corner
For a general explanation of the mesh entity, check mesh_entity.ent
To learn more about dynamic appearances, check the ArchiveXL documentation

How it works

Per default, all components in the mesh entity are active and will be added to the player when you equip your item. Which parts of them are visible is determined by their chunk masks (set everything to visible, then use the .app's partsOverride to hide parts of them).

Substitutions

Check Which substitutions exist? for a full list of your options.

Substitutions in path names will be switched out by ArchiveXL at runtime. For example, p{gender}a becomes pwa if your V has a female body gender, and pma if they don't.

To enable substitution, your depot path must begin with an asterisk *. Each substitution needs to be enclosed in braces, e.g. {gender}. All generated paths will already be dynamic.

File validation can help you spot errors in your paths.

.ent file: conditional switching

This is only documented because it's possible, not because it's good practice: ArchiveXL will create all components, hiding those that aren't matched by your current conditions.

If possible, use Substitutions together with .app file: Conditional switching and PartsOverrides: Changing other meshes.

Click to expand (DO NOT USE THIS, check the box above)

Just like in the .app file, you can apply conditional switching to component names. It works exactly like .app file: Conditional switching:

Components can also be selected by variant, this currently cannot be broken down by variant parts (eg variant.1, variant.2 etc) but it uses the full variant after the ! in the yaml.

$instances:
    - { base_color: white, ribbons: red  }
    - { base_color: black, ribbons: red  }
    - { base_color: black, ribbons: blue }
appearanceName: root_entity_dynamic_appearance_!$(base_color)+$(ribbons)

In this above example you can create filtered components by instance as follows. The one without the ! will be used by default if the variant is not in the list (eg black_pink).

entSkinnedMeshComponent: MyJacketDecals!white_red
entSkinnedMeshComponent: MyJacketDecals!black_red
entSkinnedMeshComponent: MyJacketDecals!black_blue
entSkinnedMeshComponent: MyJacketDecals

This is what your compontent can look like; in this example a different light is used based on the variant.

The diagram

Now let's look at what we just did and check the diagram. You'll see that the control files are almost identical to the vanilla variants, but that the rest of the files has gotten a lot more manageable:
