If you've been using Meshroom for photogrammetry and 3D scanning, you may be wondering how to export your final 3D model as an OBJ file for use in other 3D software. Luckily, it's a straightforward process. Here's how to do it:

1. Once your reconstruction is complete in Meshroom, navigate to the 'StructureFromMotion' node in the graph.

2. Right-click on the 'StructureFromMotion' node and select 'Compute Depth Maps.'

3. After the depth maps have been computed, right-click on the 'DepthMap' node and select 'Meshing.'

4. Once the meshing is complete, right-click on the 'MeshFiltering' node and select 'Export Mesh.'

5. In the Export Mesh window, choose OBJ as the File Format.

6. Specify the output path and file name for your OBJ file, and click 'Save.'

With these steps, you'll have successfully exported your Meshroom 3D model as an OBJ file. You can now import this OBJ file into your preferred 3D software for further editing, texturing, or rendering.

It's important to note that OBJ files only store geometry and basic material information, so you may need to export additional texture maps (such as diffuse, normal, and displacement maps) separately if you want to preserve the full appearance of your model.

By following these steps, you can seamlessly integrate your Meshroom-created models into your 3D workflow, whether for game development, animation, architectural visualization, or any other 3D-related projects. Meshroom's ability to export OBJ files makes it a versatile tool that can easily be incorporated into various 3D pipelines.

In conclusion, exporting your 3D models from Meshroom as OBJ files is a simple process that allows you to leverage the power of Meshroom's photogrammetry and 3D scanning capabilities in conjunction with other 3D software. With OBJ export functionality, you can continue refining and enhancing your 3D models in the software of your choice, opening up a world of creative possibilities for your 3D projects.
