.P File Header

The .p files have a 128-Byte-long Header. The following is the known structure of the header.

Off	00	01	02	03	04		05	06		07	08	09	0a	0b	0c	0d	0e	0f
00	01	00	00	00	01		00	00		00	VertexColor				NumVerts
10	NumNormals				00		00	00		00	NumTexCs				NumNormInds
20	NumEdges					NumPolys					00	00	00	00	00	00	00	00
30	mirex_h					NumGroups					mirex_g				01	00	00	00

All Values, that can be Read out in this part of the header are 4-Byte-Integers

Here are the meanings:

typedef struct
{
     long off00;
     long off04;
     long VertexColor;
     long NumVerts;
     long NumNormals;
     long off14;
     long NumTexCs;
     long NumNormInds;
     long NumEdges;
     long NumPolys;
     long off28;
     long off2c;
     long mirex_h;
     long NumGroups;
     long mirex_g;
     long off3c;
     long unknown[16];
} 
t_p_header;

VertexColor	Specifies if Vertex-Colors are used (0=no,1=yes; default: 1)
NumVerts	Count of Vertices
NumNormals	Count of Normals (always 0 in Battle files)
NumTexCs	Count of Texture Coords
NumNormInds	Count of Normal Indices
NumEdges	Count of Lines for WireFrame-Model
NumPolys	Count of Polygons
VertexColor	Specifies if Vertex-Colors are used (0=no,1=yes; default: 1)
mirex_h	Count of Hundrets Chunk Entries (Textures?)
NumGroups	Count of Groups
mirex_g	? (sometimes 0 or 1)(but usually 1)
