Sorry if I gave the wrong impression here. Because lightning stopped selling his models, I wondered if Greenworks had changed it's policy on the sale of Xfrog trees that one makes entirely on their own. I may wish to sell or buy Xfrog models in the future, and I was confused as to what the EULA allowed for. I have considered buying Xfrog and I wanted to know what their stance on this was. Given what was posted on the CGTalk forum, I thought lightning was cleared to sell his tree models, and I just found it odd that he shut his store down.
In any case, good luck to lightning. I still wish I could buy some of his great tree models:-)
