Hi there,

Can you show the 2nd lightmap channel for these meshes?

Also are there any meshes that might be there but is ‘hidden’, and UE4 is baking in the shadows which causes these artifacts?

Hidden meshes missing.

In other scenes on these meshes do not have these artifacts.

Another such moment:
