Hey guys,

I am learning creating HDA for game purpose and have some problem and couldn't solve it!
I created a really simple HDA to test in Houdini and try to put it in Unreal but the handles didn't work in Unreal. I tried to test it in Unity and it worked normally.
I used the Unreal Engine 4.19.2, and Houdini Indie 16.5.470 so I don't think it will be vision problem.
Here is the test video.

Thanks a lot!
