Another case of black triangles

[IRISEngineering]

Hi, I’m a new user to UE and i’m getting a lot of these black triangles and i’m not sure how to resolve them. Any idea what setting / issue could cause this? The triangles pop in/out as I move the camera in the editor.

Thanks

I think if you restart the editor, it goes away? Then it’s a lack of VRAM, you’re probably getting error messages about it.

It was a memory issue, when I decrease resolution the triangles go away. There was no warning on my screen.
