This script below works well most of the time to address the issue of
meshes not showing in the 3D Viewer.
There are various functions, I've enabled the one you want. Select a
node in the Project Tree, and all the meshes of nodes nested under it
will be exported into a single .obj file along with a .mtl file.
Haven't tested some functions which I added new now (the ones for
exporting to a file). If there's any typo it should be straightforward
Let me know.
