Why does my PCG disappear when activating path tracing at a certain distance?

(I am new to UE5)
I created an actor blueprint. I added a scene, a sqare spline and a PCG. In the PCG Blueprint I added a GetSplineData, connected it with a SplineSampler and connected that with a StaticMeahSpawner. When Lit is activated the wall is there, but when path tracing and zooming out it disappears from brick to brick… but the lods of the Meshes are on the highest setting?! Why does it keep disappearing? I just don’t get it…

Open the PCG volume and inspect where it fails. It’s likely a node or property that doesn’t support the change you did in the blueprint. It could be anything from the inputs of the blueprint or a value that increased from a float to a vec3, etc.
