Colin McRae Rally 3 .TAG and track model files

[Bigchillghost]

The models are of poor qualities:

and the submeshes would require bone parenting to reach to their correct positions.
It would be a really tedious task to support them so I'll just leave here the structures of the unpacked *.d files resulting from the tag model:

TriMesh (Non-stripped)

Code: Select all

long	MeshCount;
for (int i = 0; i < MeshCount; i++)
{
	ULONG64	Null;
	long		Vcount;
	long		FaceCount;
	for (int j = 0; j < Vcount; j++)
	{
		float	position[3];
		float	normals[3];
		float	texcoord[2];
		BYTE	 vertexColorRGBA[4];
	}
	for (int j = 0; j < FaceCount; j++)
	{
		long	AlignmentMark;
		long	TriangleIdx[3];
	}
}

TriMesh (Stripped)

Code: Select all

long	MeshCount;
for (int i = 0; i < MeshCount; i++)
{
	ULONG64	Null;
	long	 	Vcount;
	long	 	StrippedGroupCount;
	long	 	ChunkSize; //IndexChunk + VertexChunk + Header
	long	 	IndexChunkAndHeaderSize;
	float		Unknown[6];
	for (int j = 0; j < StrippedGroupCount; j++)
	{
		ULONG64		StrippedIndexCount;
		long			TriangleStrippedIdx[StrippedIndexCount];
	}
	for (int j = 0; j < Vcount; j++)
	{
		float	position[3];
		float	normals[3];
		float	texcoord[2];
		BYTE	 vertexColorRGBA[4];
	}
}

MaterialUV/MaterialUVStripped

Code: Select all

long	MeshCount;
for (int i = 0; i < MeshCount; i++)
{
	long	ChunkSize;
	long	Count;
	long	Vcount;
	long	Unknown[Count];
	for (int j = 0; j < Vcount; j++)
	{
		long	 isMaterialUV; // always == 1
		float	texcoord[2];
	}
}

Node

Code: Select all

long	NodeCount;
for (int i = 0; i < NodeCount; i++)
{
	long	 parentID;
	long	 Unknown1;
	long	 Unknown2;
	char	 NodeName[64];
	long	 NodeID; // Mapping to MeshID. Some nodes share the same ID
	float	Matrix4x4[16];
}

You'll also need the code from the tagUnpacker to get a full understand of the entire file structure.

What about the character models?
