Cannot install Houdini Engine for H Indie on Centos

[djczaps]

Hi

I purchased Houdini Indie recently to be able to play with Houdini Engine in Unreal. However I have a problem installing HoudiniEngine plugin. I cloned contained folders into /Engine/Plugins/Runtime - created folder HoudiniEngine and copied there plugin contained files. When I'm trying generate project files for Unreal I get those messages :

Generating data for project indexing... 0%Houdini Engine : Please install Houdini or Houdini Engine 16.5.603 Couldn't find the HAPI include folder! Houdini Engine : Please install Houdini or Houdini Engine 16.5.603 Couldnt find the HAPI include folder! Houdini Engine : Please install Houdini or Houdini Engine 16.5.603 Couldn't find the HAPI include folder! Houdini Engine : Please install Houdini or Houdini Engine 16.5.603 Couldnt find the HAPI include folder! 100% Writing project files... 100%

Should I extract the files to the other folders like Source , Resources in the main Unreal folder ?

Houdini environment is set and working .

Any help will be appreciated.

thanks

finally I was able to install HoudiniEnginePlugin somehow doing also 'make" command before GeneratingsProjectFiles.sh helped. However I have all the icons greyed out of HoudiniEngile in the File section in Unreal 4.20.2 . When I try to drag the Houdini Digital asset into Unreal I can see the Houdini logo 3d and icon but not an asset. Here is what showing :

Houdini Installation was not detected.Failed to locate or load libHAPIL.so. No cooking / instantiation will take place.

In the project section of the Houdini Engine correct path is detected and pointing to the right folders etc.

I discovered that it might be a HoudiniEngine plugin started and then failed to initialize correctly. Below is the output from Terminal to debug it :

it looks like sourcing houdini_setup from the same terminal from running later Unreal will fix the issue. Also make sure sourcing houdini_setup as a regular user. Now Unreal will recognize Houdini Digital Assets and all the menus here ! ;)

[djczaps]

Also I've noticed that I need to generateProjectFiles.sh each time after I source houdini_setup and run Unreal from the same Shell/Terminal to make it work with detecting and running HEngine plugin / HARS.

After reboot You need to repeat the procedure each time which is annoying but we can live with that ;)
