When using the hdaprocessor in tops how do you get Unreal to recognize a global variable. Is there a certain var name you should use like in Unity with the HEU_ENVPATH. I know in Unity you can create a env file that is then rocognized in Houdini. What is the process for Unreal in order to be able to use the hdaprocessor node in Unreal so I can point it to the correct directory of the hdas?

*BUMP*
I have the same issua - the HDAs i use in my top network are not found in UE4
