While playing the game, I found random flickering black thick lines on all the walls.

Hi ,

This looks like it’s likely due to lower lightmap resolution for your wall(s).

  • Is that wall you’re indicating a single piece of geometry or are all the walls a single piece of geometry?
  • Can you post a screenshot of your UV layout for this wall?
  • What is the lightmap resolution that you’ve set? If it’s at the default 64 try using a higher value.
  • Can you also post a screenshot of your Lightmap Density view focused on this wall. You can access this view in the Viewport > View Mode drop-down > Lightmap Density.

Thank you!

Tim

But would the lines caused by low margin UVs be flickering?
