Can't find libHAPIL.dll in UE4 Oct. 30, 2018, 5:45 p.m.

Hi Dpernuit -

I was using TCP Socket Port 9090.

I cannot remember if I restarted UE4 after changing the Session Type. I probably did since that is the general method for getting anything to kick in with UE4.

While I can get Houdini engine to engage in UE4 after turning on the Houdini Engine Debugger before, I still can not bring Digital Assets into UE4 by themselves. I am at a loss for this disconnect as well. It would be great if We could find a solution for this but at least I have a temporary work around.

Thank you for the explanation for what's going on under the hood with Houdini Engine in UE4.

Great News Dpernuit!

I changed the project TCP Socket session instead of a named pipe. That had no effect.

I tried pre-launching Houdini Engine Debugger then opened my UE4 session. Still no positive response from the UE4 Output Log. However, for giggles, I tried dropping a HDA to see If I could get any more error messages … and it worked!

I'm not sure why it is working now but it definitely worked! I did notice that the HDAs appeared in the Houdini session and disappeared when I closed the UE4 session. IS this a characteristic of the Houdini engine debugger? When I re-opened my UE4 session, my object geometries were still there but I lost all my textures. Interesting that the HDAs did not re-appear in the Houdini Session. I deleted the HDAs from the UE4 scene and re-dropped them in. The full HDAs came back with textures and the nodes re-appeared in the Houdini session.

Is this the expected behavior? Still more puzzles to figure out especially with the texture and material persistence!

This is definitely a huge step forward from where I was yesterday!

Thanks dpernuit!

I just received your message and I'll try that suggestion tomorrow when I get in to school!
