How do I stop weird Textures/lighting when I enlarge a cube?

Basically i enlarged a cube and now in my game for some reason the textures are acting weird on it looking like its dark on the bottom and light on the top.Anyone know how to fix this?

Hi The_DecafEagle75,

It could be the lightmap is too small - rather than add one large wall, try breaking it up into smaller “modular” wall parts…

nope that didn’t work :face_with_diagonal_mouth:

But it was OK before you stretched it out? Can you show a snapshot of what it looks like if you tile the original sized wall along that line?
