Spline mesh isnt casting shadow when RHI DX12 and Ray tracing is enabled? 4.23

Also, just wanna say it’s odd with how much splines are used in the new Landmass and Water systems, but ray tracing isn’t supported. Maybe I’m missing something, considering Fortnite now supports ray tracing and it uses splines everywhere on the map.

My best guess is the difference is the splines used in these systems aren’t rendered the same way that splinemeshcomponents are. Still, sad to see they aren’t supported. Pipes, wires, and roads seem like pretty standard and common use cases for splines and surely it looks odd when those objects in the scene are missing shadows or proper reflections.

Maybe there is a hybrid ray tracing mode that defaults to old render methods for components that don’t support ray tracing? Cause that would be a nice bandaid.

Yeah it would be great to get the benefits from both “worlds” and to have raytracing support all the engine features.
