I've just given it a quick try again and sorely miss some controls that are more common in Tree[d] for instance... being able to change the 'roundness' of the tree (how fast the top branches shrink vs lower ones)
I also got in some trouble trying to collapse the tree after I'd closed the dialogue box for it (it shouldn't let you close it till you've baked it?)
All in I could see myself using this if it had a few more controls. Spline management that allows you to save edited paths would be nice... so you can kinda skip forward and backward through the build process. Right now it's very lossy and you have to work forward in a specific fashion, and ending with a bake is almost essential without having headaches later trying to export/collapse the mesh.
For free though this is amazing. Set your workflow, plan things before building, and it seems to work nicely indeed!
Did anyone see that university project where someone filmed trees and a computer algorithm generated trees with the correct skeleton of branches etc? It looked very powerful.
Maybe only a few more years and we can just film some footage of trees we like and feed some coefficients into a vert/pixel shader
