SMF (Shaded Model File)
Format Specification V1.0

TEXDEF struct:
Each TEXDEF struct contains texture and shader info, and points to the primitives that use the texture.

Bytes|Field Name|Desc.
-----+----------+-----
0004 | NUM_TEXS | Contains the number of textures in the file.
-----+----------+-----
For each texture...
-----+----------+-----
0002 | TEX0_ID | ID of first texture to use in condensed shader.
0002 | TEX1_ID | ID of second texture.
0004 | SHDR_LEN | Length of shader.
-----+----------+-----
Shader data of specified length padded with F nibbles...
-----+----------+-----
0004 | PTR_MDL | Pointer to model data.

MODEL struct:
Stores the model data (duh).

Bytes|Field Name|Desc.
-----+----------+-----
0004 | NUM_TRIS | Number of triangles.
-----+----------+-----
For each triangle...
-----+----------+-----
000C | VTX_POS | Vertex positions.
000C | VTX_NRM | Vertex normals.
0008 | VTX_UVS | Vertex UVs.
000C | VTX_TAN | Vertex tangents.
000C | VTX_BIT | Vertex bitangents.

Note that a texture ID of 0xFFFF indicates a default noise texture.
