Light doesn't apply to all parts

[mjsobrep]

I have loaded in a urdf and modified the position and intensity of the directional light to try to be able to see more of what is going on in the URDF. But the light only seems to hit one component, the first one loaded. I have dug around and that component uses a MeshPhongMaterial while the others seem to use a MeshLambertMaterial. But both should be able to react to the light. When I move the light and change the intensity, I see the result on the little back bar that is circled. Any thoughts?
