Research: customization, transmog, respawn point, teleport location

Probed with tests/AbioticEditor.Tests/CustomizationProbeTests.cs (Probe1–Probe9) against the Cascade fixture saves and the real game install/paks (CUE4Parse + usmap). All property names below are exact, hash suffixes as observed in the fixtures (match by prefix - the numeric/hash suffix can differ between game versions).

---

1. Character customization (head/face, hair, clothing, colors)

Not stored in PlayerData/Player_<steamid64>.sav and not in any WorldSave_*.sav. Evidence: a raw byte scan of all four fixture player saves finds no property named Customiz*, Hair*, Voice*, Face* etc. - the only "Customization" hit is the /Game/Blueprints/DataTables/Customization/DT_TextureVariants path used by item TextureVariantRow_ row handles.

Customization lives per Steam account on the local machine, outside the world folder:

%LOCALAPPDATA%\AbioticFactor\Saved\SaveGames\<steamid64>\ScientistCustomization_<slot>.sav

(<slot> is the character slot number, e.g. ScientistCustomization_1.sav.) The file is a plain GVAS save (save class Abiotic_CustomizationSave_C, path /Game/Blueprints/Saves/Abiotic_CustomizationSave). Its top-level properties are flat, un-hashed NameProperty values - each is a row name into a customization DataTable:

Property (exact, observed)	Type	Sample value	DataTable (rows enumerated via Probe5)
Customization_Head	NameProperty	Head_M01a	DT_Customization_Head (18 rows: Head_M01a, Head_F01a, ... Head_skeleton, Head_F02chemist)
Customization_HeadAccessory	NameProperty	Glasses_None	DT_Customization_HeadAccessory (21 rows)
Customization_Wristwatch	NameProperty	Watch_Black	DT_Customization_Watch (9 rows)
Customization_Tie	NameProperty	Tie_Launch	DT_Customization_Tie (49 rows)
Customization_UpperBody	NameProperty	UpperBody_Rolled	DT_Customization_UpperBody (51 rows)
Customization_LowerBody	NameProperty	Pants_Torii	DT_Customization_LowerBody (32 rows)
Customization_HairStyle	NameProperty	Hair_Professor	DT_Customization_HairStyle (18 rows)
Customization_HairColor	NameProperty	HairColor_White	DT_Customization_HairColor (15 rows)
Customization_ShirtColor	NameProperty	ShirtColor_Blue	DT_Customization_ShirtColor (17 rows)
Customization_Shoes	NameProperty	Shoes_Torii	DT_Customization_Shoes (17 rows)
Customization_Belt	NameProperty	Belt_Black	DT_Customization_Belt (14 rows)
customization_beard	NameProperty	Beard_Professor2_A	DT_Customization_Beards (42 rows) - note lowercase c in the property name
Customization_IDCard	NameProperty	id_science	DT_Customization_IDCard (22 rows)

All tables live under AbioticFactor/Content/Blueprints/DataTables/Customization/. Two additional tables exist that have no save property in this file version: DT_Customization_Labcoats (9 rows) and DT_Customization_FannyPacks (1 row) and DT_Customization_Makeup (4 rows).

Voice: there is no voice property in any save file (player save, world save, customization save, UserSettings.sav, PlayerStatsSave.sav, Unlocks.sav - all raw-scanned). The paks contain exactly two player voice data assets (DataAssets/PlayerCharacterVoices/PlayerCharacterVoice_MaleA / _FemaleA), so the voice is derived from the chosen head's gender, not stored.

Colors: "colors" are not free RGB values; they are row choices (Customization_HairColor, Customization_ShirtColor, shoe/belt/watch color variants are separate rows). Each head row carries fixed ColorA/ColorB/ColorC FLinearColor columns and a SkinTone enum (E_SkinTones) in the DataTable - not editable per player.

Unlocked-but-not-default cosmetics are tracked in the sibling file Unlocks.sav (save class Abiotic_CustomizationUnlocks_Save_C).

Recommended C# model

public sealed record CharacterCustomization(
    string Head,            // row in DT_Customization_Head
    string HeadAccessory,   // DT_Customization_HeadAccessory
    string Wristwatch,      // DT_Customization_Watch
    string Tie,             // DT_Customization_Tie
    string UpperBody,       // DT_Customization_UpperBody
    string LowerBody,       // DT_Customization_LowerBody
    string HairStyle,       // DT_Customization_HairStyle
    string HairColor,       // DT_Customization_HairColor
    string ShirtColor,      // DT_Customization_ShirtColor
    string Shoes,           // DT_Customization_Shoes
    string Belt,            // DT_Customization_Belt
    string Beard,           // DT_Customization_Beards (property: "customization_beard")
    string IdCard);         // DT_Customization_IDCard

Reader/writer: load the GVAS file, read each top-level NameProperty by exact name (case-insensitive recommended because of customization_beard). Populate editor dropdowns from the corresponding DataTable row keys (UnlockedByDefault, DLCRequirement, AchievementRequired columns can be used for gating/labels; DisplayName column gives the in-game label, e.g. Head_M01a = "Hubert").

2. Armor transmog state

Stored per player in PlayerData/Player_<steamid64>.sav inside the CharacterSaveData root struct. Three sibling properties:

Property (exact, observed)	Type	Shape	Meaning
TransmogInventory_106_927A0B6647350D453ED2F5B7E007ADDB	ArrayProperty of Struct	6 elements	The cosmetic item applied over each armor slot. Each element is a full inventory-slot struct: ItemDataTable_18_... (RowHandle: DataTable + RowName) + ChangeableData_12_2B90E1F74F648135579D39A49F5A2313 (same layout as every other inventory slot: AssetID_25_..., CurrentItemDurability_4_..., MaxItemDurability_6_..., CurrentStack_9_..., CurrentAmmoInMagazine_12_..., LiquidLevel_46_..., CurrentLiquid_19_..., TextureVariantRow_28_..., DynamicState_39_..., PlayerMadeString_42_..., GameplayTags_45_..., DynamicProperties_50_...).
TransmogVisibility_109_1A641CB4456B8440A96AE58F027AD93C	ArrayProperty of Bool	12 elements	Visibility toggle per equipment slot (the in-game "hide armor piece" checkboxes). Fixture players: all True.
TransmogDisabledArray_145_2BA8A3F74C6661475F021A9999C06090	ArrayProperty of Bool	13 elements	Per-slot "transmog disabled" flags. Sample (player ...1479): [False, True, False, True, False, False, True, True, True, True, True, True, True].

Sample occupied transmog slot (player 76561198128277890, TransmogInventory[1]): RowName = armor_helmet_cowl (row of the item DataTable), AssetID = C3A909D846289A61DB5AFB8685B2DA37, durability 50/25, stack 1. Empty slots use the usual sentinels: RowName = None or Empty, AssetID = "-1", stack 0, LiquidLevel = -1 for the Empty form.

The 6 TransmogInventory entries line up with the 6 armor-capable equipment slots; only the ItemDataTable_...RowName matters for appearance (the rest is the standard slot payload). Transmog is therefore fully editable from the player save - it is not world/machine state.

Recommended C# model

public sealed record TransmogState(
    IReadOnlyList<InventoryItemSlot> Transmogs,   // 6 slots; reuse existing slot model, RowName = cosmetic item id
    IReadOnlyList<bool> Visibility,               // 12 flags
    IReadOnlyList<bool> Disabled);                // 13 flags

Reuse PlayerSaveReader.ReadInventoryArray for TransmogInventory_; the two bool arrays are plain ArrayProperty of BoolProperty.

3. Home bed / respawn point

Two cooperating pieces:

a) Player side - CharacterSaveData in Player_<steamid64>.sav

Property (exact, observed)	Type	Sample	Meaning
LastSafeWorldLocation_30_486FB66C419E431BD6B754B0C04C9F5B	StructProperty (Vector)	-15752.96, 11353.07, 108.15	World position used for respawn (and for "where do I load in"). All four fixture players have values within metres of their claimed beds.
LastSafeWorldGUID_98_22FA31304F1D3CE0D223A99ED23D936E	StrProperty	EB422B4245ACC9F546C26989FC936F5C	The level the location belongs to. Matches the LevelGUID top-level StrProperty of a WorldSave_*.sav; in the fixture all four players match WorldSave_Facility_Office1.sav (LevelGUID=EB422B4245ACC9F546C26989FC936F5C).
LastControlRotation_69_33E2359F425EBFDFB5CE2D84DCE6AD1B	StructProperty (Vector)	347.56, 33.02, 0	Facing on respawn/load.
TerminalRespawnID_122_768A1D184AC865DC562E39A2765F34BE	NameProperty	95CAED254C17360B69B3738E468CD49C	The respawn terminal the player registered at. Three fixture players share 95CAED25...; the fourth has 35DCF84F4AC366B8DCBB61A93D9C83C0. These GUIDs do not appear anywhere in any WorldSave_*.sav (raw scan, Probe7) - they are editor-assigned GUIDs of static respawn-terminal actors baked into the cooked levels, so treat the value as an opaque FName.

b) World side - bed claim in DeployedObjectMap

Beds are normal deployables in the owning WorldSave_*.sav (fixture: WorldSave_Facility.sav), classes Deployed_Furniture_CraftedBed_C, Deployed_Furniture_CraftedBed_T2_C (plus Deployed_PetBed_Small_C for pets). The owner claim is encoded in CustomTextDisplay_152_B59A50C74001B5D2234D9E9B0D7CAB7F (StrProperty) as:

<steamid64>}|!|{<playerName>

Samples from the fixture (WorldSave_Facility.sav):

Deployable key (AssetID)	Class	CustomTextDisplay
E10C814A41AE7459E478AD9AA96BE8E3	Deployed_Furniture_CraftedBed_C	}|!|{ (unclaimed)
CF4A2D7141497FFE1CE77C8C02B8C342	Deployed_Furniture_CraftedBed_T2_C	76561198128277890}|!|{J0K3R
6C32CBA24F897E3B31DFF0B788D40410	Deployed_Furniture_CraftedBed_T2_C	76561197993781479}|!|{Tribbes
F4A53C2940A04A5DE7350FBFA6085DA2	Deployed_Furniture_CraftedBed_T2_C	76561198179787042}|!|{Mantis

Bed position is Transform_50_85E8B13D40141C9B1308F4BB943BD753 -> Translation (e.g. Tribbes' bed at -15530.87, 11150.30, 11.0, matching his LastSafeWorldLocation -15752.96, 11353.07, 108.15).

So: claiming a bed writes the owner string onto the bed deployable, and sleeping/saving updates the player's LastSafeWorldLocation/LastSafeWorldGUID. An editor that wants to "move a player's spawn" should update both sides (or at minimum the player-side triple).

Recommended C# model

public sealed record RespawnPoint(
    double X, double Y, double Z,            // LastSafeWorldLocation_
    string LevelGuid,                        // LastSafeWorldGUID_ (match WorldSave LevelGUID)
    double Pitch, double Yaw, double Roll,   // LastControlRotation_ (stored as a Vector)
    string TerminalRespawnId);               // TerminalRespawnID_ (opaque FName GUID)

public sealed record BedClaim(
    string DeployableId,                     // DeployedObjectMap key / AssetID
    string ClassName,                        // ...CraftedBed... class path
    double X, double Y, double Z,            // Transform translation
    ulong? OwnerSteamId,                     // parsed from CustomTextDisplay before "}|!|{"
    string? OwnerName);                      // parsed after "}|!|{"

4. Player-set teleport location (Personal Teleporter sync)

There is no standalone "teleport location" property in any save. The keyword scan over player saves and world-save top levels (Probe2/Probe3 + raw byte scan) finds Teleport only in item row names (personalteleporter, recipe_personalteleporter, recipe_pest_teleporter, recipe_moistureteleporter).

The player-set teleport target is carried on the Personal Teleporter item itself, in its inventory slot's ChangeableData_12_2B90E1F74F648135579D39A49F5A2313:

Field	Type	Sample	Meaning
PlayerMadeString_42_CC0B72B24DBEAB2CC04454AAFFD4BBE9	StrProperty	572B5DD1440E8BBA76348C94FE7CF11A,	The sync target: the GUID of the deployable it was synced at, with a trailing comma. In the fixture every target resolves to a DeployedObjectMap key of a crafting bench in WorldSave_Facility.sav (verified by the existing TeleporterLinkTests).
AssetID_25_06DB7A12469849D19D5FC3BA6BEDEEAB	StrProperty	85BA63E5431AAA6F12219B97DCF294B7	The item's own instance GUID - not the link.
LiquidLevel_46_... / CurrentLiquid_19_...	Int / Byte	100 / E_LiquidType::NewEnumerator8	Charge: the teleporter stores its energy as "liquid" type 8, level 0–100.

Three of the fixture teleporters point at the same bench (572B5DD1440E8BBA76348C94FE7CF11A,), one at another bench (948C8BE8470F20E130F26A9BF7A5676D,). An unsynced teleporter has an empty PlayerMadeString. The same encoding applies wherever the item sits (player inventory, world container, dropped item).

Recommended C# model

public sealed record TeleporterLink(
    string ItemAssetId,        // AssetID_ of the teleporter item
    string? TargetDeployableId,// PlayerMadeString_ minus trailing ',' ; null = unsynced
    int ChargeLevel);          // LiquidLevel_ (0..100), CurrentLiquid_ enum value 8

Editing: write "<deployableGuid>," into PlayerMadeString_; the target must exist as a DeployedObjectMap key (crafting benches are the only observed/valid targets).
