I’ve worked out how to do a bit of sculpting on the trunk of the tree. GoZ is meant to work with The Plant Factory but it doesn’t (for me). However there is another process that does seem to work, and creates the possibility of an interesting hero tree for an environment. This example was only a couple of minutes work, but I’m sure if I spend a bit of time on it I can come up with a pretty good result. Happy. Sort of.
