Why am I getting a blue "trail" behind my models?

I get a blue trail behind my models when I move around close to them, why is it happening?


I think UE4 might be culling the meshes too aggressively and the models are not being loaded in quick enough. Not sure about a solution.

Thanks for the reply! Maybe I have to use a Cull Distance Volume to keep the models loaded or something?

In youtube you can use , and . to go frame by frame back and forth. When doing that you see that the blue trail is the stars because your models are missing/culled.

Those pillars. How do they look with a default material? Is the material doing anything to offset the surface?
