Problems with material - Only applied on one side of mesh

Hello forum!

I just made this building quick in Blender (Wanted to test the size in UE4) when I came across this problem:

Now, I know I’ve seen this before here on the forums, but I just can’t find it again. Could someone quickly explain how ti fix this? Is it Blender side fault, or UE4?

You mean the “missing” wall part? ->
-make sure that your vertex normals are potining into the right direction :slight_smile:
Edit Mode - Space - Flip Normals

Exactly! Thanks. Appreciate it :slight_smile:
