Research: Transmog slot mapping + appearance preview assets

Date: 2026-06-11. Probes: tests/AbioticEditor.Tests/TransmogAppearanceProbeTests.cs (Probe1 = fixture-save dump, Probe2/3/5 = cooked widget/enum dumps, Probe4 = customization tables).

Task 1 - TransmogInventory_106_* slot mapping (DEFINITIVE)

Source of truth: the cooked transmog UI AbioticFactor/Content/Blueprints/Widgets/Inventory/W_Inventory_Transmog.uasset. Its six W_TransmogItemSlot_C subobjects each carry an explicit SlotIndex, SlotType (E_InventorySlotType) and tooltip text:

Transmog index	Role	Widget	SlotType	Tooltip	Empty-slot icon
0	CHEST	W_TorsoArmorSlot	NewEnumerator14	"Chest Armor"	/Game/Textures/GUI/icon_armor
1	HEAD	W_HeadArmorSlot	NewEnumerator5	"Head Armor"	/Game/Textures/GUI/icon_helmet
2	LEGS	W_LegsArmorSlot	NewEnumerator6	"Leg Armor"	/Game/Textures/GUI/icon_pants
3	BACK (backpack)	W_BackpackSlot	NewEnumerator7	"Backpack"	/Game/Textures/GUI/icon_backpack
4	ARMS	W_ArmArmorSlot	NewEnumerator12	"Arm Armor"	/Game/Textures/GUI/icon_arm
5	FULL BODY SUIT	W_SuitArmorSlot	NewEnumerator13	"Full Body Suit"	/Game/Textures/GUI/icon_suit

Note: W_TorsoArmorSlot serializes no SlotIndex property - i.e. it keeps the class default 0 (UE omits default-valued properties). Confirmed by save data.

Fixture-save corroboration (Probe1, all four Cascade/PlayerData/Player_*.sav):

• Player_76561198179787042: transmog [0]=armor_chest_apron (chest item), [1]=armor_helmet_chefhat (helmet).
• Player_76561198128277890 (J0K3R): transmog [1]=armor_helmet_cowl (helmet).
• Transmog indices 0–5 are exactly the first six EquipmentInventory_11_* indices (0=chest, 1=head, 2=legs, 3=backpack, 4=arms, 5=suit) - same SlotIndex and SlotType values in both widgets.

Empty transmog slots appear as RowName Empty (the usual sentinel) or None (observed only in Player_76561197993781479, indices 0/1/2/4 - treat both as "no transmog applied").

Equipment slot index -> role (from W_Inventory_EquipSlots.uasset, authoritative)

Each EquipSlot_* (W_InventoryItemSlot_C) export carries SlotIndex + tooltip:

Index	Tooltip (in-game name)	SlotType	Editor's current label	Correct?
0	Chest Armor (EquipSlot_Torso)	14	CHEST	yes
1	Head Armor	5	HEAD/HELMET	yes
2	Leg Armor	6	LEGS	yes
3	Backpack (not in this widget; item data confirms backpack_*)	7	BACK	yes
4	Arm Armor	12	ARMS	yes
5	Full Body Suit	13	EYES?	no -> SUIT
6	Headlamp	15	HEADLAMP	yes
7	Trinket	16	TRINKET	yes
8	Wristwatch	17	WATCH	yes
9	Hacking Device (keypad)	18	TOOL	rename -> HACKING DEVICE
10	Off-Hand Armament (shield)	19	SHIELD	yes
11	Trinket (second)	20	TRINKET2	yes
12	Companion Pet	21	EXTRA	rename -> COMPANION

E_InventorySlotType (Blueprints/Data/E_InventorySlotType.uasset) declaration order: 0,1,2 (None/Inventory/Hotbar-ish), then 14(Chest),5(Head),6(Legs), 7(Backpack),12(Arms),13(Suit),15(Headlamp),16(Trinket),17(Watch),18(Hacking), 19(Shield),20(Trinket2),21(Companion) - matching equipment order 0..12.

TransmogVisibility_109 (12 bools) / TransmogDisabledArray_145 (13 bools)

• The component CDO (Blueprints/Characters/Abiotic_TransmogInventoryComp.uasset) declares TransmogVisibility[12] and DisableTransmogArray[12], both defaulting to all-True. The saved TransmogDisabledArray_145_* has grown to 13 entries (patch drift, same way EquipmentInventory grew to 13 with the Companion slot).
• Most plausible mapping: both arrays are indexed by EquipmentInventory slot index (0=chest ... 11=trinket2, [12]=companion in the 13-long array). The 12-long TransmogVisibility_109 covers equipment slots 0–11.
• Evidence: Player_76561197993781479 has TransmogDisabledArray = F,T,F,T,F,F,T,T,T,T,T,T,T - False exactly at 0 (chest), 2 (legs), 4 (arms), 5 (suit): the four armor-visual slots a player hides to show the scientist outfit (the per-slot "eye" toggle, W_TransmogToggleButton). All other fixtures are all-True (default). TransmogVisibility_109 is all-True in every fixture, so its per-index semantics are unverified - but its CDO size (12) and name pair it with the same equipment indexing.
• Editor guidance: expose per-equipment-slot "armor visible" toggles for indices 0/1/2/3/4/5 only (the visual slots); preserve the rest untouched.

Task 2 - Appearance preview assets in DT_Customization_*

All 13 customization tables share one row struct. Exact (hash-suffixed) columns, observed via Probe4 on DT_Customization_Head, _HairStyle, _UpperBody, _HairColor, _ShirtColor, _IDCard:

UI recommendations:

• Every picker can show DisplayName + the Icon texture; icons live under /Game/Textures/GUI/CustomizationIcons/<Heads|Hair|Tops|ShirtColors|IDCards|...>.
• DT_Customization_HairColor rows point Icon at the engine placeholder /Engine/EditorLandscapeResources/WhiteSquareTexture - i.e. the game tints a white square with ColorA. Render a ColorA swatch for hair colors.
• DT_Customization_ShirtColor has both real icon_shirt_* textures and a meaningful ColorA; either works (swatch is cheaper).
• Row counts: Head 18, HairStyle 18, UpperBody 51, HairColor 15, ShirtColor 17, IDCard 22.
