A UI is a graphic that is drawn to the screen, on top of everything else in the scene. It can accept user input and is used to display menus, UI elements, background images, boss health meters, logos, etc. It can draw either a simple 2D Texture or a 3D Model (but not both).

Format

UIs are entity assets. Some notes on the 0x54 byte header:

• The rotation and scale only apply to a UI with a model (ModelAssetID). A UI with a texture ignores these properties.
• The position is measured in screen space. The XY coordinates are measured in pixels, (0,0) being the top left corner of the screen. The Z coordinate represents depth and is used to determine the draw order (a UI with a higher depth will be drawn behind one with a lower depth).
• The asset ID at 0x10 is an optional Surface that is applied to the model.
• The asset ID at 0x50 is an optional AnimList.

Following the header:

Offset	Type	Variable	Description
0x54	int	uiFlags	Always 52.
0x58	struct (size: 4)	dim
0x58	short	Width	in pixels.
0x5A	short	Height	in pixels.
0x5C	AssetID (Texture)	Texture	Texture for the UI. Note that you cannot show both a model and texture at the same time. If you set this to something other than null, ModelAssetID will be ignored.
0x60	Vector2	uva	Texture Coordinate (Top Left)
0x68	Vector2	uvb	Texture Coordinate (Top Right)
0x70	Vector2	uvc	Texture Coordinate (Bottom Right)
0x78	Vector2	uvd	Texture Coordinate (Bottom Left)
