Some insights

Hi, thanks for your great work!
I am here to ask for some possible insights from you. I can see NDS can reconstruct a perfect surface with lots of details on it. I wonder how the details of surface can be captured. The mask loss can capture coarse shape so I think the details are captured by the shading loss.
But why it works perfectly without any geo-prior and only with RGB images? Could you please give some insights or something related on that?

Aside from that, I also want to know if it's necessary to capture images under a fixed light? I mean if the light position is just the direction of camera view direction and move with it, will the result quite different?
