Grass Meshes are base assets, so they start with their 0x8 byte header, then are followed by:

zGrassMeshAsset

class zGrassMeshAsset : public xBaseAsset
{
public:
    signed int numVertices;
    signed int numFaces;
    xVec3 min;
    xVec3 max;
};
Offset Type Variable Description
0x08 s32 numVertices Amount of zGrassMeshVertex
0x0C s32 numFaces Amount of zGrassMeshFace
0x10 Vector3 min
0x1C Vector3 max

zGrassMeshVertex

class zGrassMeshVertex
{
public:
    xVec3 position;
    float height;
    xVec3 normal;
    unsigned char r;
    unsigned char g;
    unsigned char b;
    unsigned char a;
};
Offset Type Variable Description
0x00 Vector3 position
0x0C f32 height
0x10 Vector3 normal
0x1C Color rgba

zGrassMeshFace

class zGrassMeshFace
{
public:
    unsigned short a;
    unsigned short b;
    unsigned short c;
};
Offset Type Variable Description
0x00 u16 a
0x02 u16 b
0x04 u16 c
