= MCH Field Character Models =

Each MCH file contains a skinned-animated model representing a character on the field or world Maps. There appear to be multiple files of the same character representing differnt Level of Details.

They usually contain multiple TIM textures (standard PSX textures), mesh geometry, bones, skeleton heirarchy information and skinning information. The whereabouts of the Bone Animation data is currently unknown.
