Model from Noesis export did not respond to light?

[Stalketeer]

I exported some Final Fantasy XII models from Noesis, but it seems that those models did not respond to point light or directional light.
They does respond to ambience light though.
I don't think this is a problem of the exported format, or the program that I use to load the models. Maybe it's something to do with Noesis itself.
Any light that can be shed on this matter? Any way to fix this?

The skeleton lighting is flat, same as the character's shirt
