	Grass Mesh
Type	Base
Base Type	0xCD
Games used	The Incredibles;

Format

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
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
0x00	u16	a
0x02	u16	b
0x04	u16	c
