Enum SkinFile 

pub enum SkinFile {
    New(Skin),
    Old(OldSkin),
}

Enum to represent either format variant

Variants

New(Skin)

New format with version field (camera files)

Old(OldSkin)

Old format without version field (character models)

Implementations

impl SkinFile

pub fn parse<R: Read + Seek>(reader: &mut R) -> Result<Self>

Parse a SKIN file with automatic format detection

pub fn load<P: AsRef<Path>>(path: P) -> Result<Self>

Load a SKIN file from a path with automatic format detection

pub fn save<P: AsRef<Path>>(&self, path: P) -> Result<()>

Save the SKIN file

pub fn write<W: Write + Seek>(&self, writer: &mut W) -> Result<()>

Write the SKIN file to a writer

pub fn get_resolved_indices(&self) -> Vec<u16>

Get resolved vertex indices for rendering

CRITICAL CORRECTION: After empirical analysis, the triangles array already contains the final vertex indices for rendering. The previous assumption about two-level indirection was incorrect.

For both embedded skins (pre-WotLK) and external .skin files (WotLK+):

• The triangles array contains the direct vertex indices for mesh connectivity
• No additional indirection is needed
• Values like [76, 21, 23] are the actual vertex indices to use for triangles

pub fn indices(&self) -> &Vec<u16>

Get raw indices array (vertex mapping/lookup table)

Note: For triangle rendering, use get_resolved_indices() instead. This method returns the indices array which serves as a vertex mapping table. In practice, this array typically contains sequential values [0,1,2,3…] and is used internally by the M2 format for vertex organization.

pub fn triangles(&self) -> &Vec<u16>

Get triangles regardless of format

pub fn submeshes(&self) -> &Vec<SkinSubmesh>

Get submeshes regardless of format

pub fn batches(&self) -> &Vec<SkinBatch>

Get material lookup table regardless of format

pub fn convert(&self, target_version: M2Version) -> Result<Self>

Convert this skin file to a target version

This handles cross-format conversion automatically:

• WotLK and earlier use old format (no version field)
• Cataclysm and later use new format (with version field)

The conversion preserves all mesh data while adjusting the header structure as needed for the target version.

pub fn bone_indices(&self) -> &Vec<u8>

Get the bone indices regardless of format

pub fn is_new_format(&self) -> bool

Check if this is a new format SKIN file

pub fn is_old_format(&self) -> bool

Check if this is an old format SKIN file
