Thank you. It took me quite a long time of trial and error when I first tried to use Reflections and then Transparency. I would suggest that you study the examples of reflective and transparency work that is provided in the Formulas folder in M3D and copy those examples from there. Dark-Beam also has some reflections examples in tutorial form. I will say that Reflections and transparencies work in different ways. Reflections needing a dark Ambient light while Transparencies needs much more Ambient light. It's too much to write down all the intricacies here. You have to work at it with much patience. It is frustrating but successful results makes you feel like it all worth it.
