I have a simple HDA that is placing unreal instances along a spline. I'm trying to expose the instance path string as a parameter so I can switch the asset placed along the spline in unreal rather than pre-defining it in the HDA. This doesn't appear to work though. Is this functionality supported? I've verified the HDA working correctly when I just point it to a string rather than exposing it as a parameter.
Thank you for any information you can provide!
