Texture for base is not correct

#1 Did you edit the sun at all? That looks more of a lighting problem.

#2 No, nothing other than following the tutorial for familiarization with the editors. This is a bare bones nothing added other than what you see. I'll read farther up and see if there is a reference to a lighting change. The older version without the light package didn't do this so maybe that is the problem.

#3 Try this:

new Sun() {
      canSaveDynamicFields = "1";
      azimuth = "45";
      elevation = "45";
      color = "0.35 0.35 0.35 1";
      ambient = "0.15 0.15 0.27 1";
      CastsShadows = "1";
         direction = "0.57735 0.57735 -0.57735";
         rotation = "1 0 0 0";
         scale = "1 1 1";
         position = "0 0 0";
   };
