Vertex formats with bone data support multiple bone assignment. In this case, the sum of all bone weights is 0x64.

Observed sample vertex formats:
Vertex components are stored as one of the above data types, and the vertex component declaration contains a multiplier that adapts the values to the float version which the game will use.
 
For example, color RGBA values are stored as bytes, and the multiplier converts them from 0-255 to 0-1.0, and position components using short values are normalized via the multiplier to take advantage of the entire short value range.
