Created a basic spline mesh and the mesh isnt casting a shadow. Disabled ray tracing and the shadow was being cast. Is this a bug with 4.23?
I have the same problem in 4.24.2.
Splines arenāt supported yet for Raytracing
Is this still the case? I have a translucent material that works fine on static meshes but on a spline it fails to appear entirely.
Raytracing is suppose to be production ready with the recent release of 4.25, so it would be odd if it didnāt support something as core as splines.
I still can not get Spline Mesh Components to cast shadows with Ray Tracing Activated. As the above post states, it seems odd this is omitted from a production read feature.
Same in 4.26, no raytraced reflection or shadows for spline meshes sadly.
Also, just wanna say itās odd with how much splines are used in the new Landmass and Water systems, but ray tracing isnāt supported. Maybe Iām 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 arenāt rendered the same way that splinemeshcomponents are. Still, sad to see they arenāt 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 donāt support ray tracing? Cause that would be a nice bandaid.
Yeah it would be great to get the benefits from both āworldsā and to have raytracing support all the engine features.
How can we report this? I think its a necessity. I imagine its not so hard to achieve!

grab all the splines and Merged them, as it does not lose its shape. it will convert spline actors to a static mesh and cast shadows while Raytracing is enabled.
As,āConvert to static meshā option deletes all spline points.

Just spent the whole day trying to understand why a set of fences was casting shadows in preview lighting but not after lighting was properly built. Literally been hours trying option after option. Finally stumbled on this thread. Just adding a voice I hope Epic will heardā¦ itād be awesome if this issue was fixed.

thanks for this, literally saved my day.
Big Thanks form KOREA
You saved my life!
Is this still the case now (Unreal Engine 5.0.3) does anyone know? Seems to still be an issue specifically when I turn on ray traced shadows with spline meshes but just want to check Iām not missing something.
On the latest version of UE4 - 4.27.2, shadows for splines do not work when tracing rays. Iām making a product for both UE4 and UE5, it looks like Iāll have to abandon the abundant use of splines when working with RTX.
Thank you for sharing the problem, otherwise I would have had to look for solutions for a long time, spend a lot of time on it and not achieve results.
