This is a converter of Wavefront OBJ files to Orbiter's MSH format. It was created because of dissatisfaction of existing ones and a need for batch conversion for the Nexus: The Jupiter Incident mod I have in works.
Features:
 - Vertex optimization (equal vertexes are combined)
 - Texture coordinate fix (Orbiter uses the reverse one of the OBJ format)
 - Mesh and material names are preserved
Notes:
 - If the texture names have TGA format, they extension will be changed to DDS
 - The input OBJ file is required to be "full" (i.e. have both normals and texture coordinates)
 - Program requires .NET Framework 4 Client Profile to run
Please post bugs and feature requests in the corresponding forum thread.
