Mesh file

A Trainz mesh file is a file containing 3D geometry in one of the file formats directly supported by Trainz:

• IM file format (deprecated; not recommended.)
• TrainzMesh file format.
• PM file format (obsolete; do not use).
• LM.txt file format (this is a text-based container format that references child meshes).

The mesh file contains a number of render chunks and may contain skeleton information, attachment points, or reference local texture files.
