Instanced Static Meshes Not Appearing in Path Tracer

Development Rendering

These cables use instanced static meshes along the spline.
They dont show in the path tracer (UE 5.2)

So far I’ve:

  • Tried enabling nanite on/off with them.
  • Eliminated shaders as a cause.
  • Made sure “rendered in ray traced view” is enabled on assets.

It’s not a bounds thing, the actor origin is right near the beginning of the spline.

I do this on each instanced mesh in the cable blueprint, doesn’t help.

Any workarounds for this? Thanks.

You can convert the spline meshes to static meshes

Thank-you!

I wanted to try merging them but I didn’t see the option ANYWHERE so I thought it was just not doable with this actor.

I cant believe there’s stuff in the “Actors” tab at the top that isn’t visible in the inspector or through right-clicking.

Much appreciated.
