To support the continued development and ease my wife’s pain of me talking constantly about trees. Please Donate bellow.

To view the future development Roadmap of JZTrees, follow the trello board here: https://trello.com/b/bKcqHstM/jztrees-development-roadmap

License Types:

Apprentice or Indie. (no FX at this time).

JZTREES requires Houdini 18.5. Any version before 18.5 will not support procedural wind.

Downloading JZTREES

1. Using gitclone download this repository to chosen location on your harddrive or shared network.

2. Download the zip from the repository then unzip the contents of JZTREES onto a chosen location on your hardrive or shared network. E.g. C://

NOTE: It is not reccomended to put JZTREES in your home houdini folder.

Installing JZTrees - VIDEO INSTALL: https://www.youtube.com/watch?v=aPHrA2YlDMw

In the JZTREES root there is a .json file which is used to point houdini towards where the toolkit is located.

1. Open the .json file in a text editor and adjust the variable "JZTREES" to match the location you have placed the toolkit.

E.g._ "JZTREES": "C:\Users\joshu\Documents\houdini_plugins\JZTREES",_

2. Open you houdini home folder. E.g. /houdini18.5. Following create a 'packages' folder in this location.

If you already have a packages folder skip this step.

3. copy the .json file into the 'packages' folder.

4. To test the toolkit has installed correctly open houdini, go into a GEO node and try creating a JZTREE SOP. E.g JZT_Trunkgen

5. Success! enjoy using JZTrees

Modelling tools to generate trees and vegetation
