Looks like the model is being loaded and rendered, but all in black.
With the right camera positioning I can see this.
EDIT:
I´ve added some code from @Mugen87
from this post:
var ambientLight = new THREE.AmbientLight( 0xcccccc, 0.4 );
scene.add( ambientLight );
var pointLight = new THREE.PointLight( 0xffffff, 0.8 );
camera.add( pointLight );
scene.add( camera );
Looks like some light did good, this is another model, from REVIT, but when I zoom out:
ZOOMOUT
No luck with the small city model, it’s entire black,
I can only see one red square for a moment
