Hey folks. I'm having a bugger of a time trying to get the "Unreal Material" inside an HDA I've built to work correctly in Unreal 4.26. Here's some screenshots of my setup. Going cross eyed trying to get it to work. Any tips would be appreciated.
Basic "string" variable here at the top level of the HDA for a specific group of primitives.
Here's how it's referenced inside the Unreal Material node inside the HDA.
Inside of Unreal I copy the relative reference from the desired material instance into the HDA field for this piece.
Just another screenshot showing that the reference was copied from the material. Ignore the ugly material. I made it pretty hard to miss so that I'd know it worked if I got so lucky lol. Hideous I know.
Hey folks. This is solved. The issue is about where your HDA is placed inside of Unreal. For me, everything started to work once I placed the HDA inside of the Houdini Engine folder. I had mistakenly created an "HDA" folder inside my Unreal project and was bringing in my HDAs to that folder. The file referencing didn't work until I moved them which is odd to me because the Houdini Engine folder lives at the same level as the HDA folder I created. Anyway, it works for me know.
