I would like to share my new version of Blenders tree generator.
I have made many changes to create a wider variety of trees more realistically, added features, and make it more intuitive.
Some changes include:
better branch splitting
new branching algorithms for more realistic branching structures
easy to use and correct leaf orientation
options to use an object for the leaves
interface partly re-arranged so properties often used together are in the same panels.
Back curvature now adds to curvature rather than replace it
Vertical attraction can now be set individually for each split level
note: this affects older saved trees which wont look the same with this version.
I have removed some of the presets that didn’t work any more, and added my own presets.
I hope you all find this useful and let me know of any problems you have or features you would like to see.
hi, I recently did some changes to sapling in Blender release.
I’ll certainly give your script a look.
Are you interested in developing sapling in Blender?
hi, what changes were made recently?, I started with the version in blender 2.74.
If blender devs want my version in a release that would be great, but I don’t know what that entails.
no news yet, I fixed paths in Blenders version & had a good look at all the somewhat iffy menu’s then compared with new sapling version. Pretty sure it’s much better. Stull a couple of things to be done, armature does not work with pruning, it needs a poll or if/else to prevent using the two together. a way to apply the prune also would be good & help with this issue.

Is it still relying on curves which are bevelled?
I would recommend looking into using the new skin modefier on single edges. It makes for much more realistic shapes for the trunk and the branches and especially where they meet.
ejnaren, I too would like to have mesh-skininng of the branches. the skin modifier seems to have too many kinking issues to be used for branches. Does any one know of a way to do the curve skinning?
There is s way to use the skin modefier. Either you can set the number if segments or I used the sub division modefier on top of it.
Once I also added a displace in the sub d to roughen up the tree trunk and branches…
I’ve recently added a lot of useful changes to improve the tree generator.
Try out the new version and if you have any questions or suggestions about it, let me know, I appreciate your feedback.
tried the new version with blender2.74 works well.tree form feels more natural.if you are interested in implementing base offset for branches will be useful to have,another feature is fractal jitter (limited to one or two directions) for branches.
With the rectangular mesh I have to use an alpha map, and set the transparent bounces to a high level to avoid black spot.
I have noticed that with hexagonal leaves, I can turn off the transparent shadows check-box in the light paths panel, and the render is twice as fast. That is true for external scenes, with lots of trees, of course.
At the moment the work flow is: separate the leaves -> UV unwrap one leaf -> transfer the UV to the others -> join all the leaves.
Separating the leaves takes ages on my laptop
