If you're working with 3D models, you may need to export MG files as OBJ for use in programs like Maya and Blender. Here's a quick guide on how to do it.

1. Open the MG file in your 3D modeling application, such as Maya or Blender.

2. Once the file is open, navigate to the 'File' menu and select 'Export' or 'Save As'.

3. In the export options, choose 'OBJ' as the file format.

4. You may have the option to adjust settings such as scale, rotation, and texture export. Make any necessary adjustments based on your specific needs.

5. Choose a file name and location for the exported OBJ file, then click 'Export' to save the file.

Now you have successfully exported your MG file as an OBJ, which can be easily imported into other 3D modeling software for further editing or use in projects. Remember to check the specific requirements of your target application to ensure a smooth import process.

Exporting MG as OBJ opens up a world of possibilities for collaborating with others, sharing your models, or using them in different applications. It's a simple process that can greatly expand the versatility of your 3D modeling work.
