Description of the problem
I update the FBXLoader today and find that it show wrong normal (I guess is the normal) when lighting for some fbx model. I will show different view for the same scene in the following, note that I have set the intensity of the directional light to 1000 ( I think big enough ). However, it shows wrong effect.
It show in r87 like (the sun icon is a directional light):
and in r89:
In addition, reversely in r87, the FBXLoader also has some bugs (the icon in the scene is a rectarea light)：
which show in r89:
So I think when fix some bug in r89, it maybe leads to the oppositive bug.

1 is big enough. That is a clear sign the normals are not correct.
In r.88 the normals appear correct, and the model is loaded on its side.
In r.89, the normals are not correct, and the model is loaded right-side-up.
