Hello. I'm just sharing my frustration - yesterday me and my colleague spent several hours trying to understand why Houdini Engine is producing no output in Unreal. Session connected fine - no errors in console, all seems to be working but no output!
After few hours of ultimate frustration, we discovered that my colleague had a regular Houdini Engine license - not the Indie License, while I have an Houdini with Indie license to make hdas. There really should be a message somewhere - preferrably error message in console, that there is a license mismatch or error - not just a silent fail!
