Is there a way to copy the various materials and their prosperities, not to make an instance that borrows from it, but to have a copy to play with?
For example, I saw that the Ocean and Lake materials had a lot going. I do not want to play with the settings there because I will overwrite the original. If I could simply copy the whole thing over and place it in my own folder, then I could play with it without fear of permanently changing its properties to my chagrin.
