It is hard to say without seeing your code.
Generic advice: in 2D the order in that you draw determines what is covering what (like on a canvas). In 3D it’s different. Here the z value determines what is behind what. The order in that you draw doesn’t matter anymore.
So in your example it might be the case that you should use a translate(0,0,2); right before text() command
OR perhaps post your code please
