Hello devs!

Creating a house project where every piece of wall is changable. So every piece is a blueprint…but somewhere is no problem and somwhere is. After lightbake (this is production settings and wall lightmaps are set to 64) got this problem (those shadowy lines on wall)

What i don’t understand is why the problem is not at every connection only at some (no problem at all on this side-3White walls next to each other)

Lightmaps are not correct for unreal engine or just with errors. Create correct or you can recreate in engine on import stage. Problem can be something not visible, because specific light/shadow in area.

Sry for late response but posted it at 2 AM…and yeah you were right it was caused by the lightmaps again, those fky lightmaps :D… just changed lightmap coordinations to the ones i made in blender and it seems to be working :slight_smile: thanks!
