Tesign would be the guy to ask cause he's got the program. If those pluggins are for those applications and not X frog. Well that's kind odd isn't it? How many programs around that do odd things like that. The industry standard right now is you make your program work with everyone elses not the other way around. If that's the way it is it's really not worth it. Think of it how many programs are out there that can import 3d max files. How much is 3d max worth. As for Tesign's bread and butter um my take in that is Onxy Tree is a better way to go cause the meshes are way way smaller, leaves are in you garden, and go look at the gallery there. You can make some cool trees there and the program is dead simple. Lots of programs out there that can make cool meshes but if the resulting size is too big there kind of pointless. Optimizing them is part of the programmers job and no not a add on it should be a standard tool.
