Dear Friend: I would like to know how I can cerate my own unique Eco-Systems using Vue 6 Esprit. One of the problems that I am having is that the Eco-system tab is either grayed out or it is not availble in the "Type" material tab of my Vue 6 Esprit. So, How can I set unique Eco-Systems with my Vue 6 Esprit? Sincerely, Fidelity2.
