Are you ready to take your 3D modeling to the next level? With Meshroom, a free and open-source photogrammetry software, you can create stunning 3D models from a series of 2D images. Once you've processed your images and generated a textured mesh in Meshroom, you may want to export your model as an OBJ file for use in other 3D modeling software or for easy sharing. Here's how you can do it:

1. **Select your Mesh** - In Meshroom, select the mesh you want to export as an OBJ by clicking on it in the 3D Viewer.

2. **Export as OBJ** - With the mesh selected, go to the 'File' menu and choose 'Export' > 'OBJ...'. This will open a dialog box where you can specify the name and location for your OBJ file.

3. **Adjust Export Settings** - In the OBJ export dialog, you can adjust the export settings such as the scale, texture options, and coordinate system. Make sure to set these options according to your specific needs and the requirements of the software you'll be using the OBJ file in.

4. **Export** - Once you've configured the export settings, click 'Export' to save your mesh as an OBJ file. Meshroom will then process the mesh and save it to the location you specified.

5. **Verify OBJ file** - After the export is complete, you can verify the OBJ file by opening it in a 3D modeling software such as Blender, Maya, or 3ds Max. Check that the texture and mesh are correctly imported and that the scale is correct.

6. **Share or Use in Other Software** - Now that you have your mesh exported as an OBJ file, you can easily share it with others or use it in other 3D modeling software for further editing and rendering.

By following these simple steps, you can export your 3D models from Meshroom as OBJ files and take full advantage of the incredible photogrammetry capabilities that Meshroom has to offer. Start creating amazing 3D models today and unleash your creativity with Meshroom!
