Hi Val2,
So I think it's a matter of updating the plugin. I'm going to reload the plugin to see.

I assume BMoI doesn't work in Blender 4.0+ yet? They've radically changed some things in the Blender API, and add-ons need updating.

Hi everyone,
For my part, after comparing BmoiConnector and the classic export in .obj format, with triangle only and more polygons I get better results.
I have to say that I use Blender almost exclusively for rendering.

You're right, working with OBJ export from MoI is not a hassle, and Blender has recently updated its OBJ import / export module.
