LEO_Tools (Beta):

A collection of HDAs for SideFX Houdini. I'll upload them whenever I created a new one for my projects.

They are made with Houdini 18(.5) Indie and should only work with Indie, Apprentice or Educational.

Also I'll add some useful code to the useful folder whenever I encounter something cool. Newer tools are made for Python 3 but should still work with Python 2 builds of Houdini.

List of current HDAs:

All nodes are documentated via the houdini documentation. To view the documentation press F1 or the questionmark-icon in the parameters.

SHELF TOOLS:

LEO Random Ramp: Updates or adjusts ramp parameters by random values to generate more interesting results.

SOP:

LEO Color Ramp Picker: Allows the interactive creation of a color ramp in the viewport. Demo Video
LEO Group Intersecting Object: Generates a group based on the intersection with another geometry.
LEO Variant Merge: Merges geometry and simultaneously creates a variant attribute for the "Copy to Points"-SOP. Demo Video
LEO Connect Points Intersect: Creates lines between nearby points which do not intersect with another geometry.
LEO Object Render: Creates an object-level node which only renders the incoming geometry.
LEO Attribute Split: Splits an incoming geometry based on an attribute.
LEO Weighted Random: Creates an random attribute based on weighted inputs. Demo Video
LEO Lattice: Easily place a lattice deformer anywhere on a mesh. Demo Video
LEO Linked Subnets: Connects subnets together to copy nodes and parameters. Demo Video or More Information

OBJ:

LEO Object Render Child: Object-level node created by LEO Object Render.

MAT:

Installation:

Download or clone this repo and place it somewhere safe.

Method 1: houdini.env

The houdini.env on Windows 10 should be located at

c:/users/[username]/Documents/houdini[version]

Add following to the env but change the "LEO" path to the downloaded directionary

Add the path to both the HOUDINI_PATH as well as the PYTHONPATH

Example houdini.env file

LEO = "E:/Projects/LEO_Tools"

HOUDINI_PATH = $LEO;&
PYTHONPATH = "$LEO/scripts/python;&"

Method 2: Plugin / Packages

Requires Houdini 17.5+

Put the LEOTools_package.json file into the packages folder.

It should be located here on Windows:

c:/users/[username]/Documents/houdini[version]/packages

On Linux:

~Library/Preferences/Houdini

Finally update following line to match your downloaded directionary

"LEO": "D:/Resources/HDA/LEO_Tools"

NOTE: If you have Python installed on your system you can run the included create_package_json.py file. This will create a new LEOTools_package.json with the path to the current directionary.
