Installation

A few steps must be undertaken for Houdini to be able to load and render with the Golaem plug-in.

Installing the Golaem For Houdini plug-in

The Golaem for Houdini plug-in can be found can be found in the extension section of the Golaem product in your Autodesk account and it has the following directory structure:

Adding Golaem For Houdini to your Environment

Then, for Houdini to be able to find the Golaem For Houdini plug-in, its path needs to be added to the predefined HOUDINI_DSO_PATH environment variable and a couple of others. There are many ways to add a path to an environment variable, however for our test, we chose to create a bat / shell file to launch Houdini with the correct environment.

Linux

#!/bin/sh
# Set Environment Variables for Golaem
export GOLAEM_INSTALL_PATH=/home/golaem/Golaem-9.2.2-Houdini20.0-Python310-linux
export LD_LIBRARY_PATH=${GOLAEM_INSTALL_PATH}/lib:\&

# Set Environment Variables for Houdini
export HOUDINI_DSO_PATH=${GOLAEM_INSTALL_PATH}/procedurals/houdini:\&
export PYTHONPATH=${GOLAEM_INSTALL_PATH}/procedurals/houdini/python:\&
export HOUDINI_TOOLBAR_PATH=${GOLAEM_INSTALL_PATH}/procedurals/houdini/shelf:\&
export HOUDINI_UI_ICON_PATH=${GOLAEM_INSTALL_PATH}/procedurals/houdini/icons:\&

# Set Environment Variables for USD
export PXR_PLUGINPATH_NAME=${GOLAEM_INSTALL_PATH}/procedurals/usd

# export HOUDINI_DSO_ERROR=3

# Launch Houdini
/opt/hfs20.0/bin/houdinifx

Troubleshoot

You can also uncomment the line setting the HOUDINI_DSO_ERROR environment variable to 3 in order to get more logs and check what is the issue when loading the plug-in within Houdini
