Why does my static mesh blueprint have a shadowing issue?

Hello,

Here’s my problem :
I created a BP for repeating a mesh along an axis (like the one in the content examples). I use the “Add StaticMeshComponent” node with “mobility” set to “static”. But when I build the light the shadows don’t cast correctly.
As you can see on the screenshots the light isn’t baked on the repeated static meshes (wall, ladder, guard-rail…).

PS. The shadows cast correctly if the light are set to “mobility” “movable”

EDIT : the meshes weren’t UV unwrap… so the shadows work now.

Just wanted to clarify the answer here.
