ModelDef exporter/importer for Maya/XNA/C#
- ModelDef is a custom, clean model format for use in game engines. This was written because the FBX pipeline is buggy and the shader/material information from Maya was not used to the fullest extent. Supports multiple UV-sets, tangents, binormals, some custom attributes like UseAlpha (for alpha-textures) and DrawBackfaces (for some meshes, like tree leaves). Easy to extend to support more attributes at a material or any DAG path level.

Scene exporter/importer for Maya/XNA/C#
- Exports each transform and mesh in the maya scene as individual ModelDef files and generates an XML that describes how to recompose the scene. The framework to export more information like lights, cameras and such are there, but not currently used/maintained since my pipeline (XNA/ModelDef) doesn't need it. Exports each mesh and its transform after moving it to the origin to remove absolute values from the exported ModelDeffile. For use with large levels and scenes. The importer imports the scene into its own container class.

Custom-data exporter/importer for Maya/XNA/C#
- Exports custom data about a character to an XML file. Currently configured custom data includes exporting player camera and item mount points. Follows a similar structure to the scene exporter. Exports idle animation name and animation data if used with the MoveLister (link soon). For use with characters with animations. The importer imports the scene into its own container class.
