Thread: Dragon Nest MSH structure

MSH structure:

• Header
• BoneData
• MeshData
• OtherData

Header

Code:

struct Header{
    char name[256];	//Eternity Engine Mesh File 0.1
    int version;  //file version
    int meshCount;
    int unknown1;	//0x1
    int unknown2;	//0x0
    Vec3F bbMax;
    Vec3F bbMin;
    int boneCount;  //overall bone count
    int unknown2;	//0x1 or 0x0
    int otherCount; //other elements
};

BoneData
offset 0x400

Code:

struct BoneData{
	char boneName[256];		
	Vec4F transformMatrix[4];	//Bone transformation matrix
};

MeshData

Code:

struct MeshInfo{
	char sceneName[256];
	char meshName[256];
	int vertexCount;
	int indexCount;
	int unknown;
	int renderMode;
	char empty[512 - 16];
};

struct MeshDataPointer{//pointer
    char* pFaceIndex;	//0x2(unsigned short) * indexCount
    char* pVertexData;	//0x4(float) * 3 * vertexCount
    char* pNormalData;	//0x4(float) * 3 * vertexCount
    char* pUVData;	//0x4(float) * 2 * vertexCount
    char* pBoneIndex;	//0x2(unsigned short) * 4 vertexCount
    char* pBoneWeight;	//0x4(float) * 4 * vertexCount
    int*  pBoneCount;
    char* pBoneName;	//0x100(char [256]) * boneCount
};

VertexData elements - the vertex in 3d space xyz coordinate, Vec3F structure data.

Chinese description

• VertexIndex元素 - 即顶点索引,是程序画面的顺序数据,索引的是顶点数据.每个元素使用unsign short类型保存数据.
• NormalData元素 - 即法线数据,是每个顶点的法向数据,以三维空间坐标x,y,z表示.每个元素使用Vec3F结构保存数据.
• UVData元素 - 即UV贴图数据,是每个顶点在二维贴图空间映射的u,v坐标.每个元素使用Vec2F结构保存数据.
• WeightIndex元素 - 即权重索引,是每个顶点的权重索引,每个顶点最多可以索引4个骨骼.每个元素使用4个unsign short类型保存数据.
• WeightData - 即权重数据,是每个顶点的权重数据,每个顶点最多可以拥有4个骨骼权重.每个元素使用Vec4F结构保存数据.
• BoneIndex - 即骨骼索引,用以给骨骼编序,只保存骨骼名称.每个元素使用char [256]字符型数组保存数据.

OtherData

Code:

class Vec2F{
	public:
	float x;
	float y;
	Vec2F(){x = 0; y = 0;}
	Vec2F(KFbxVector2 &vector){
		x = vector.GetAt(0);
		y = vector.GetAt(1);}
	Vec2F(KFbxVector4 &vector){
		x = vector.GetAt(0);
		y = vector.GetAt(1);}
};

class Vec3F : public Vec2F{
	public:
	float z;
	Vec3F() : Vec2F(){z = 0;}
	Vec3F(KFbxVector4 &vector) : Vec2F(vector){
		z = vector.GetAt(2);}
};

class Vec4F : public Vec3F{
	public:
	float w;
	Vec4F() : Vec3F(){w = 0;}
	Vec4F(KFbxVector4 &vector) : Vec3F(vector){
		w = vector.GetAt(3);}
};

P.S. If some one can translate this into En, please add your comment

Grooguz what is use of this??? is this for customizing the character in dragon nest?

What's the target of that ?

Can you explain please ?
