From what I remember of Onyx tree pro, aren't the tree parameters for each tree stored in a small file with an extension of *.tre and not a mesh, yes you can export to a mesh if you want, but you can also save the trees "Parameters"... I don't know if this would infringe upon copyright, but say you come up with a wizz bang tree, would it be possible to share this file (wizzbang.tre) with other users, as the file on its own is useless, it takes TreePro to translate the data from this file into the mesh. Kinda like a PZ3 file.. This would get around inyerface's wanting to share files with other Onxy users. Just my thoughts. Cheers Matty.. aka ToolMan :)
