Example: How to Add a Hair (e.g., ID: 4)​

To add hair (like heads, eyes, or any other elements), you need to add it to the corresponding DataTables.

There are 3 main steps:

  • Add the element in its respective "MeshData" DataTable.
  • Add the element in the UI DataTable (used to determine its display in the UI).
  • Add the element’s ID to the CreatorUIDataAsset to activate it in the Creator UI.

DataTable: "MeshData"​

Reminder about IDs

Important: IDs must always be:

  • Numeric
  • Unique
  • Placed in both the RowName and the structure itself

In this example, I add the hair asset in the DataTable DT_ACC_EpicHmn_A_Hair, as shown below:

DataTable: "UI"​

Now, do the same in the corresponding UI DataTable. In this case, it’s DT_ACC_EpicHmn_UI_Hair.

Reminder: Verify which asset is used

How do you know you’re using the right DataTable?

As always, get used to checking references using the Reference Viewer. This tip applies to all assets!

CreatorUIDataAsset​

Don’t forget to activate your newly added element in the CreatorUIDataAsset of your species. This defines what is available for use in the in-game creation UI.

Why is this important?

The filter system allows you, in production, to keep certain elements out of the in-game creation menu (e.g., unlockable items).

Where is the asset from? As always, use the Reference Viewer.
