Hello !

Im having trouble linking Unity to Houdini.
Im not very familiar with Houdini but im trying to write a script that uses Houdini API. Ive downloaded Houdini and ive installed the custom package in Unity, but when i try to create a “Pipe Session” it wont let me. It gives me an error and says it cant find the libraries but there are files in the “Plugins” folder, does it need more?

I´ve googled around and cant find anyone else having this problem, anyone here knows whats going on?

It is not finding the Houdini installation, which is usually located in C:/Program Files/Side Effects Software. When you install Houdini, it should add a registry entry which is then used to look up where Houdini is installed.

You can try the following to fix it:

• Re-install Houdini, and the Unity plugin.
  
• Specify where Houdini is installed in the Unity plugin by going into the settings menu and specifying the location: HoudiniEngine > Plugin Settings > GENERAL > Override Houdini Install Path. Note that this is only available in Windows.
  

Hi!

I did override the Houdini Install Path in Unity and after the Unity editor restart it works. But if Houdini has an error (like the one when you hit "undo" a couple of times) it exists from the Unity editor, and the next time I open it I have to do the path change again. And, of course, I have to restart again for the changes to take effect.

The settings that you enter in the plugin settings should be saved in heu_settings.ini in the main project directory. Make sure that this file exists. The settings should be saved for your next launch, so you shouldn't have to set it again.
