Hello good people!
We're having trouble installing Houdini Engine for Unity on macOS. I've tried
  • Reinstalling Houdini and the engine
  • Importing the plugin to different locations in the project.
  • Changing the path to the .app in the Houdini engine settings.

But I always get this message.
Plugin was built with:
Houdini: 19.5.640
Houdini Engine: 5.0.7

Unable to detect Houdini Engine installation.
License Type Acquired: Unknown

Failure possibly due to: 

System PATH: 
/Applications/Houdini/Houdini19.5.640/Frameworks/Houdini.framework/Versions/Current/Resources/bin
/usr/bin
/bin
/usr/sbin
/sbin

Looks like it's related to Apple Silicon M2. I got it working on Intel-unity. Please fix this for M2, sideFX!

Hello,

I had this same problem on macOS, where Houdini Engine in Unity would not recognize my Houdini installation, and it had nothing to do with setting a different version of Houdini in the HoudiniEngine > PlugIn Settings in Unity.

The issue was that I had downloaded the HoudiniEngine plugin from the Unity Asset Store instead of using the Houdini Launcher to download the correct .unitypackage.

To fix this on M2 macOS, I used the Houdini Launcher to download the latest version of the HoudiniEngine for Unity and then manually installed it in Unity by choosing Assets > Import Package > Custom Package…. The package was here:
/Applications/Houdini/engine/Unity/20.5.332/HoudiniEngineUnity.unitypackage

Installing that fixed my licensing issues.
