very cool addon, very helpful
could you pls port it to support OpenMVS files as well?

the cameras and sparse point cloud is stored in a very easy to parse bin file (see Interface.h), while the rest of the output are in PLY

How about joining the development efforts for one Meshroom Blender Add-in?
@tibicen (meshroom2blender) (I chose to post on your Issues by random as I had to ask this somewhere)
@SBCV (https://github.com/SBCV/Blender-Addon-Photogrammetry-Importer)
@Stwend (https://github.com/Stwend/MeshroomTools)
@stuarta0 (https://github.com/stuarta0/blender-photogrammetry)

All the Add-ins are slightly different and would benefit from a joined development.

I can not import MG files since Meshroom, probably "StructureFromMotion" is not working because after change the "Inter File Extension" since "ABC" to "PLY" that do not work, and I know that because I opened the "StructureFromMotion" folder

I have absolutely no experience with custom Blender plugins.
When I tried to install the plugin as a zip file (of the whole repository) and as the __init__.py script both approaches failed.
In the end what worked was renaming init.py to import_meshroom.py and installing that.
Is there a proper way of installing the plugin?

Hi,
I'm facing a problem when i try to import a meshroom project. It seems I'm asked for some exif metadata if I'm not wrong.

I try to add the focal length with ExifToolGUI but it seems that Meshroom doesn't read it...
Is there a way to overcome this issue since meshroom gave me a model anyway ?

BTW, thx a lot for this script !

I'm not a python guy, sorry for not sending a PR.

It looks like the fileformat of meshroom changed.
