Coudn't find HPAI!

[questionkiller]

My plugin menu items are grey and compile with the following tips Creating makefile for HouUEEditor (no existing makefile) 1>Houdini Engine : Looking for Houdini Engine 17.5.425 in C:/Program Files/Side Effects Software/Houdini Engine 17.5.425 1>Houdini Engine : Looking for Houdini 17.5.425 in C:/Program Files/Side Effects Software/Houdini 17.5.425 1>Houdini Engine : Failed to find Houdini 17.5.425, will attempt to build using the latest installed version 1>Houdini Engine : Please install Houdini or Houdini Engine 17.5.425 1>Couldn't find the HAPI include folder! 1>Houdini Engine : Please install Houdini or Houdini Engine 17.5.425 1>Couldnt find the HAPI include folder! It seems like i should do some changes in HoudiniEngineRuntime.Build.cs but how to do it?

What version of Houdini / UE4 are you using?

The plugin normally tries to use the registry to detect your houdini install folder, as it used to require the HAPI (Houdini Engine API) libraries to build. It indeed seems to be failing in your case, so one thing you could try is: For each of the plugin's build.cs file

• set bIsRelease to false
• set the HFSPath string to your Houdini's install path.

But normally, the install path should be found in the registry... how/where did you install H ?
