Vertex Resource

Vertex Resource (OVTX)

If the Resource Type is OVTX (0x4F565458), the header is immediately followed by the vertex array definition.

Vertex Header

Offset	Size	Type	Description
0x40	4	u32	Count
0x44	...	[Vtx]	Array of Vtx structures

Vtx Structure

Each Vtx structure (16 bytes) represents a vertex for the N64 RCP:

Offset	Size	Type	Description
0x00	2	s16	X Position
0x02	2	s16	Y Position
0x04	2	s16	Z Position
0x06	2	u16	Flag
0x08	2	s16	Texture Coordinate S (10.5 fixed point)
0x0A	2	s16	Texture Coordinate T (10.5 fixed point)
0x0C	1	u8	Color Red / Normal X
0x0D	1	u8	Color Green / Normal Y
0x0E	1	u8	Color Blue / Normal Z
0x0F	1	u8	Color Alpha

YAML Configuration

To define a vertex array asset in the configuration, use the VTX type.

Field	Type	Description
type	String	Must be VTX.
offset	Integer	The offset of the vertex array in the ROM/binary.
count	Integer	The number of Vtx structures to parse.
symbol	String	(Optional) The symbol name for the asset.

Example:

- type: VTX
  offset: 0x8000
  count: 32
  symbol: my_vertex_buffer
