Convert TMO to another file type
To convert TMO animations to another format, you need 3D Custom Girl or other 3D software.
Convert a file to TMO
To convert other file formats to the "Game 3D Model File" file type, you need software like 3D Custom Girl or a similar tool.
About TMO files
The .TMO file is a proprietary 3D animation, pose, and model container created exclusively for 3D Custom Girl, a legacy Japanese character customization game. Modders primarily manipulate these files using community-developed scripts and plugins for 3D modeling platforms like Blender or Metasequoia. Users need to convert .TMO files because the format is entirely closed, undocumented, and relies on an outdated, niche software engine. You cannot natively open these files in modern game engines like Unity or view them in web browsers. The best conversion targets for a .TMO file are OBJ for static meshes, FBX for rigged animations, or PMD and PMX for integration into MikuMikuDance. Be aware that converting away from the native format frequently causes a loss of custom physics parameters, game-specific materials, and specialized rig constraints. This format is notoriously difficult to process because the data structure is proprietary to a single developer, meaning general-purpose tools lack the necessary decoding libraries. Even with closed formats, our analysis can sometimes detect supported underlying or embedded mesh structures, making viewing or conversion possible.
Convert.Guru analyzes your TMO file, detects the exact format, and lets you read the text inside.
If you want to convert TMO file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use 3D Custom Girl or similar software from the "3D Animation and Posing" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to TMO, try 3D Custom Girl or another comparable tool in the "3D Animation and Posing" category.
The TMO Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TMO converter.
