M2 File Header

The information in the M2 file is generally like this.

Global texture list

Global vertex list

• Position
• Blend Weights
• Blend indices
• Normal
• Texture coordinates

(4 levels for each model ?)

• Vertex indices (the vertices used in this level are the global vertex list indexes)
• Face indices (each triangle has three indexes in the global vertex list)
• Vertex properties (each vertex index has one, unknown)
• Submeshes (generally one for each material)
• Texture units (reference subemesh, global texture List Index, number of texture units bound)

Global volume (used for collision detection ?)

Animation (animations, global sequences)

Skeleton)

Additional rendering information: color, transparency, texture animation, model mixing, etc.

Special effects: strip, particle

Lighting

Camera

The knife looks pretty, so you can use it:
