How are you.
I tried to import monkey.fbx using THREE.FBXLoader();
But it was failed.
So, I visit https://threejs.org/editor/ and import the .fbx file to editor.
Also, not clear.
Please see error page.
How to fix:
THREE.FBXLoader: The loader relies on THREE.NURBSCurve for any nurbs present in the model. Nurbs will show up as empty geometry.
Please help me.
