Well, yes, I must have missed your earlier post Charles... :) But yes, what Charles and Eric are saying makes the best sense, although I doubt they'll come out with a complete tree editor and Eon could capitalize on this by making it as a plug in for other modelling programs... And guitta, I know what you mean that they're expensive, but the ones out in the market are just overpriced... :) Actually making the plant generator itself is not such a big deal... I think with the plant info that eon has for solid growth, they could make something that allows editing of all the parameters, branch length, trunk size, type of leaf, etc... And inasmuch as yes, we have the capability of doing it by hand now, it's a lot of work... Just getting the masks to work is a lot of work... :) Anyway, we'll probably just wind up with a Banyan tree or Baobab, like in Le Petit Prince... :)
