The browser console reveals that you are using OBJ. What happens when you import the file into Blender or a website like https://sketchfab.com/? Do you have correct results?

But these OBJ files are ok. Example here also OBJ files: http://polidomes.com/tent/polidome-75.php
and it works very well no problem with glitches and black textures. So I think that there is problem with code.

When I upload 150.OBJ and 150.MTL at https://blackthread.io/loader/, it looks okay. This website uses THREE.OBJLoader.
