Axiom is available for the latest 20.0, 20.5, & 21.0 production builds of Houdini. Daily builds are not supported.
After downloading Axiom, unzip the files. You will find a json file and a folder. This is the Houdini package. If you look inside the folder you will see each Houdini version and platform that is supported.
<aside> 💡 Axiom packages have a version, revision, and build number associated with them. It is safe to install multiple versions and revisions together such as Axiom 2.2, 3.3 & 4.0 however you can not have multiple builds of a particular version and revision installed at the same time such as Axiom 4.0.064 & 4.0.065.

<aside> 💡 When a new production build is released by SideFX we will compile a new plug-in for that version. You will need to download and re-install Axiom if you want it to work with the new Houdini build.
</aside>
Next you will need to move the json file and folder to your Houdini preference’s packages folder.
<aside> 💡 If the packages folder does not exist please create it.

Your preferences folder can be found here on your OS.
Windows
C:\Users\USERNAME\Documents\houdini##\
macOS
/Users/USERNAME/Library/Preferences/houdini/##/
<aside> 💡 On macOS you may need to use Finder’s go to folder feature to get to this directory.
</aside>
Linux
/home/USERNAME/houdini##/
Now you can launch Houdini and search for the Axiom nodes in SOPs.
